DETAILED DESCRIPTION OF THE DRAWINGS
While the concepts of the present disclosure are susceptible to various modifications and alternative forms, specific exemplary embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit the concepts of the present disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
Referring to FIG. 1, in one embodiment, a surface camera system 10 includes a surface camera assembly 12, a control module 14 located remotely from the camera assembly 12, and a production center 16. The camera assembly 12 is configured to be embedded in the surface of a track 18. The track 18 may be embodied as any type of track or roadway including, but not limited to, a motor-sports raceway track, a horse track, a public street, an airport runway, or other track, roadway, street, or path configured to support vehicular and/or pedestrian traffic.
The camera assembly 12 includes a support housing 20 and a camera housing 22 coupled to the support housing 20. A camera 24 is secured in the camera housing 20. The camera 24 is illustratively embodied as a high-definition camera, but may be a standard definition camera in some embodiments. For example, in one particular embodiment, the camera 24 is embodied as a high definition camera model number FCB-H10, which is commercially available from Sony Corporation of America of New York, N.Y. However, in another particular embodiment, the camera 24 is embodied as a standard definition camera model number QN42, which is commercially available from Elmo Company, Limited of Plainview, N.Y.
The camera housing 22 is coupled to the support housing 20 such that the a top surface 26 of the housing 22 is generally flush with a top surface 28 of the track 18 so as to reduce disturbance to vehicles or other objects traveling over the camera housing 22. In some embodiments, as discussed in more detail below, the top surface 26 of the camera housing 22 may be generally dome-shaped and include a window positioned therein such that the camera 24 has a clear view of the track 18 in a particular direction. In such embodiments, the camera 24 may or may not be located in the camera housing 22. In other embodiments, the camera housing 22 may include a small dome protrusion that extends upwardly from the top surface 26 of the camera housing 22 such that the camera 24 has a clear view of the track 18 in a particular direction. In such embodiments, a portion of the camera 24 may be located in the camera housing 22.
The support housing 20 and the camera housing 22 may be formed from any material sturdy enough to withstand the forces exerted on the track 18. For example, in embodiments wherein the surface camera assembly 12 is embedded in a motor-sport track, the support housing 20 and camera housing 22 may be formed from steel, cast aluminum, or other hard metal. However, in other embodiments, the housings 20, 22 may be formed from other materials such as plastics, ceramics, or the like.
In some embodiments, the camera housing 22 may be coupled to the support housing 20 in one of a number of orientations such that the camera 24 is directed toward any one of a number of directions. A new camera angle may be obtained by rotating or otherwise positioning the camera housing 22 in a new orientation with respect to the support housing 20 and securing the camera housing 22 in place. Additionally or alternatively, in some embodiments, the surface camera assembly 12 may include an actuator 30 and associated linkage, which is coupled to the camera housing 22. The actuator 30 is operable to rotate or otherwise move the camera housing 22 to one of a number of different orientations such that a plurality of camera angles are available. Additionally, in some embodiments, the camera housing 22 may also include one or more ports or openings 32, 34 for dispensing a cleaning solution and/or air onto a window of the camera housing 22 and/or the lens of the camera 24. Further, in some embodiments, the surface camera assembly may include a microphone 23, which may be coupled to the camera housing 22 or the support housing 20.
As discussed above, the control module 14 is located remotely from the surface camera assembly 12. Depending on the type of camera 24, the distance at which the control module 14 is positioned relative to the camera 24 may be limited. For example, in one particular embodiment, the control module 14 is located within about fifty feet of the camera 24 to ensure good signal levels. The control module 14 is communicatively coupled to the camera 24 via a number of interconnects 36. The interconnects 36 may be embodied as any type of interconnects capable of facilitating communication between the camera 24 and the control module 14. For example, the interconnects 36 may be embodied as any number of wires, cables, printed circuit board traces, vias, and/or the like.
In embodiments wherein the surface camera assembly 12 includes the actuator 30, the control module 14 may be coupled to the actuator 30 via a number of interconnects 38. The interconnects 38 may be similar to the interconnects 36 and may be embodied as any type of interconnects capable of facilitating communication between the control module 14 and the actuator 30. In embodiments wherein the surface camera assembly 12 includes the microphone 23, the control module 14 may be coupled to the microphone 23 via a number of interconnects 25, which may be embodied as any type of interconnects capable of facilitating communication between the control module 14 and the microphone 23. In addition, in embodiments wherein the surface camera assembly 12 includes the ports 32, 34, the control module 14 may be coupled to the nozzles 32, 34 via a number of conduits 40, 42. The conduits 40, 42 may be embodied as any type of conduit or tube capable of transporting the cleaning solution, solvent, and/or air for the cleaning of the lens of the camera 24 and/or window of the camera housing 22. Additionally, in such embodiments, the control module 14 may include or otherwise be coupled to a number of reservoirs for storing the cleaning solution and/or air. For example, the control module 14 may be coupled to a fluid reservoir 44 for holding an amount of cleaning fluid or solvent via a conduit 46 and to a pressurized air reservoir 48 via a conduit 50.
The control module 14 may include any number of circuits, modules, and/or devices for controlling the camera 24 and processing video and/or images received therefrom. In addition, in embodiments wherein the camera housing 22 includes the ports 32, 34, the control module 14 may include control circuits and other devices such as pumps or the like for transporting solvent and air from the reservoirs 44, 48 to the ports 32, 34.
The production center 16 may be embodied as a number devices depending upon the particular application of the system 10. For example, the production center 16 may include any number of monitors, computers, video and image processors, receivers, transmitters, and/or other electrical and mechanical devices. The production center 16 may be embodied as a fixed production center such as a building or room or a mobile production center such as a mobile vehicle. As such, the production center 16 may be located remotely from the control module 14. The production center 16 is communicatively coupled to the control module 14 via a number of interconnects 52. The interconnects 52 may be embodied as any type of interconnects capable of facilitating communication between the production center 16 and the control module 14. For example, the interconnects 52 may be embodied as any number of wires, cables, printed circuit board traces, vias, and/or the like. In one particular embodiment, the interconnects 52, or a portion thereof, are embodied as a number of fiber optic cables, which carry the video and/or images generated by the camera 24 and the control module 14.
In use, the surface camera assembly 12 is embedded in the surface of the track 18. To do so, a hole sized for the assembly 12 may be formed in the track 18 by drilling or other means. The assembly 12 may be inserted into the hole and secured therein via mechanical restraints and/or adhesives. The hole may be “patched” around the assembly 12 using concrete, asphalt, or other material that may or may not match the remaining surface of the track 18. The interconnects 36, 38 and conduits 40, 42 may be routed from the surface camera assembly 12, under the track 18, and to the control module 14. During an event, such as a motor-sporting event, the camera 24 may be used to generate images and video of the point-of-view of the top surface 28 of the track 18.
The video and images data is transmitted from the camera 24 to the control module 14 via the interconnect 36. The control module 14 may be configured to process the video/image data before transmitting the video and images to the production center 16 via the interconnect 52. For example, in embodiments wherein the camera 24 is a standard definition camera, the control module 14 may be configured to “up convert” the standard definition image/video to a high-definition format. The video and/or images may be viewed and further processed in the production center 16 before transmission to remote viewing devices such as spectator televisions.
In embodiments wherein the surface camera assembly 12 includes the actuator 30, the control module 14 may be responsive to control signals received from the production center 16 to activate or otherwise control the actuator 30. That is, the camera housing 22 and camera 24 may be remotely positioned from the production center via use of the control module 14 and the actuator 30. Additionally, in embodiments wherein the camera housing 22 includes the ports or openings 32, 34, the control module 14 may be responsive to control signals received form the production center 16 to pump an amount of cleaning solution or solvent from the fluid reservoir 44 and/or an amount of air from the pressurized air reservoir 48 through the conduits 40, 42. In this way, a user of the production center 16 may clean the lens of the camera 24 and/or a window of the camera housing 22 remotely. In such embodiments, replaceable film and the like are not required to ensure a clean view for the camera 24.
Referring now to FIG. 2, in one embodiment, the surface camera assembly 12 includes the support housing 20, a first spacer 60, a second spacer 62, and the camera housing 22. In the illustrative embodiment, the support housing 20 has a substantially cylindrical shape, but may have other shapes in other embodiments including, but not limited to, hexagonal, rectangular, oval, and/or the like. Additionally, in some embodiments, a base plate 64 may be secured to the bottom of the support housing 20. The base plate 64 may have a rectangular shape as shown in FIG. 2, a circular shape, or other shape based on the particular application. The support housing 100 may also include a conduit port 66. In use, the interconnects 36, 38 and the conduits 40, 42 are routed to the camera housing 22 and camera 24 through the conduit port 66.
The spacers 60, 62 are used to adjust the height of the camera housing 22 relative to the support housing 20. Any number of spacers of various heights may be used in particular applications. That is, although the illustrative camera assembly 12 of FIG. 2 includes two spacers 60, 62, any number of spacers may be used in other embodiments. Additionally, the spacers may be of various heights. For example, the first spacer 60 is a “small” spacer and may have a height of about one to three inches in some embodiments. The second spacer 62 is a “large” spacer and may have a height of about three to six inches in some embodiments. The spacers 60, 62 have a shape similar to the support housing 20 and are configured to be coupled to each other and/or the housing 20.
In the illustrative embodiment of FIG. 2, the camera housing 22 is secured to the second spacer 62 (or to the housing 20 in embodiments without the spacers 60, 62) via a retainer ring 68. In the illustrative embodiment, the retainer ring 68 is secured to the second spacer 62 and secures the camera housing 22 in place via compression forces between the retainer ring 68 and the spacer 62. However, in other embodiments, the retainer ring 68 may be secured to or otherwise be coupled directly to the camera housing 22. As discussed above, the camera housing 22 may be secured in any orientation relative to the support housing 20 via the retainer ring 68. Additionally, the position or orientation of the camera housing 22 may be altered by removing the retainer ring, re-orientating the camera housing 22, and re-securing the retainer ring 68 to secure the camera housing 22 in the new orientation/position.
In the illustrative embodiment of FIG. 2, the upper or top surface 26 of the camera housing 22 is generally domed-shaped and includes a pie-shaped recess 70 defined therein. A camera window 72 is positioned in the recess 70 to provide a viewing port for the camera 24. As discussed in more detail below, a portion of the camera 24 may be positioned within or otherwise coupled to the camera housing 22. In some embodiments, the camera housing 22 may include one or more ports or openings 80 similar to the ports 32, 34. The ports 80 are positioned in the camera housing 22 such that liquid and/or air ejected therefrom is received on the window 72 of the housing 22 and/or a lens of the camera 24.
Referring now to FIGS. 3-7, in one particular embodiment, the camera housing 22 is embodied as a camera housing 100 having a cylindrical shape defined by a curved sidewall 102. The housing 100 includes a lip 104 extending about the mid-section of the sidewall 102, which is used to position and secure the housing 100 to the support housing 20 or a housing spacer depending upon the particular application. The camera housing 100 includes a top surface 106 and a bottom surface 108. The top surface 106 of the camera housing 100 is substantially dome-shaped and includes a generally pie-shaped recess 1110. The recess 110 is defined by a substantially planar bottom wall 112, sidewalls 114, 116, and a rear wall 118. In the illustrative embodiments, the rear wall 118 is substantially orthogonal to the bottom wall 112. A window 120 is positioned in the rear wall 118 of the camera housing 100 to provide a viewing port for the camera 24. The camera housing 100 may also include a pair of ports or openings 122 similar to the ports 32, 34. The ports 122 are illustratively positioned in the bottom wall 112 of the housing 100 and directed toward the window 120 such that the window 120 may be cleaned by the liquid and/or air ejected therefrom (see FIG. 7). In such embodiments, the camera housing 100 may include a corresponding pair of tubes or conduits 124 to provide the liquid or air.
The top surface 106 of the housing 100 extends upwardly from the side surface 102 at a selected angle and height so to not interfere with vehicles, animals, or persons that travel over the camera housing 100, even at high rates of speed. For example, in one embodiment, the housing 100 is shaped such that the top surface 106 extends no more than about 0.5 inches above the top surface 28 of the track 18 when the housing 100 is coupled to the support housing 20. For example, in one particular embodiment, the domed, top surface 106 extends vertically above the bottom wall 112 no more than about 0.5 inches. In another particular embodiment, the domed, top surface 106 extends vertically above the bottom wall 112 about 5/16th of an inch. Additionally, in one particular embodiment, the slope of the top surface 106 is less than 90 degrees relative to a plane defined by the bottom wall 110. In another particular embodiment, the slope of the upper surface 106 is about 60 degrees or less relative to bottom wall 110. In a further particular embodiment, the slope of the upper surface 106 is about 30 degrees or less relative to the bottom wall 110. In yet a further particular embodiment, the slope of the upper surface 106 is about 10 degrees or less relative to the bottom wall 110. Additionally, in one embodiment, the top surface 106 extends a distance of about 0.5 inches or less above the
As shown in FIGS. 5-7, the camera housing 100 includes an internal cavity or chamber 130 having an opening 132 defined in the bottom surface 108. The cavity 130 is sized to receive the camera 24, a portion of the camera 24, and/or an adaptor coupled to the camera 24 as discussed in more detail below. The camera housing 100 also includes an aperture 132 in communication with the cavity 130. The window 120 is positioned in the aperture 132. The illustrative camera housing 100 is configured for use with a high definition camera, and as such, the aperture 132 and window 120 have a generally rectangular shape.
In some embodiments, the camera 24, or a portion thereof, may be positioned in the internal cavity 130. However, in embodiments wherein the high definition camera 24 is too large for such positioning, the camera 24 may be secured to the bottom surface 108 of the camera housing 100 such that the view of the lens of the camera 24 is vertical relative to the camera housing 100. As such, the bottom surface 108 may include a plurality of threaded apertures 134 to facilitate attachment of the camera 24 (or an adaptor coupled thereto) to the camera housing 100. Additionally, in such embodiments, a portion of the camera 24 may or may not be positioned in the cavity 130. Further, as discussed in more detail below, a camera adaptor may be used to redirect the view of the camera 24 outwardly through the window 120. To do so, the adaptor may include a mirror or the like as discussed in more detail below.
Referring now to FIGS. 8-13, in one particular embodiment, the camera 24 is embodied as a high definition camera 200. The high definition camera 200 may be embodied as a complete high definition camera or only a portion thereof. For example, in some embodiments, the camera 200 may be embodied as the imager electronics and devices of a high definition camera. In such embodiments, other portions of the high definition camera may be located remotely from the housing 100 such as in the support housing 20 or in the control module 14.
The camera 200 is coupled to the bottom surface 108 of the camera housing 100 via an adaptor 300. A portion of the adaptor 300 is received in the cavity 130 of the camera housing 100. Due to the relatively large size of the high definition camera 200, the adaptor 300 is used to couple the camera 200 to the housing 100 and redirect the view of the camera 200. The adaptor 300 includes a lens assembly 302, an adaptor plate 304, and a mirror housing 306. When assembled, a portion of the adaptor such as the mirror housing 306 is received in the cavity 130 of the housing 100.

The mounting plate 310 also includes a plurality of threaded apertures 322 for securing the adaptor plate 304 to the lens assembly 302. The lens 312 is secured to the mounting plate 310. The lens 312 is sized to be positionable in the cavity 130 of the housing 100 and is substantially smaller than a typical high definition camera lens. For example, in one particular embodiment, the lens 312 has a diameter 328 of about 0.5 inches. The lens 312 has an adjustable focus. As such, to ensure the focus of the lens 312 is not inadvertently adjusted during use, the lens focus locking ring 314 is coupled to the lens 312 to lock the focus of the lens 312 to the desired setting. The locking ring 314 is secured to the mounting plate 310 via a pair of screws 324 and includes a threaded aperture 326 defined on a sidewall 328. A set-screw (not shown) or other securing device is threaded into the aperture 326 and contacts a side of the lends 312 to lock the focus of the lends 312.
As illustrated in FIGS. 10 and 12, the adaptor plate 304 includes a substantially planar base plate 330 and a post 332 extending upwardly from the base plate 330. The post 332 illustratively has a cylindrical shape but may have other shapes in other embodiments. The post 332 includes a passageway 334 defined therethrough. The passageway 334 is sized to receive the lens 312 when the lens assembly 302 is coupled to the adaptor plate 304. In the illustrative embodiment, the post 332 also includes a slot 336 defined in a top surface 338 of the post 332. The slot 336 is sized and shaped to receive filter and iris control devices of the camera 200. In such embodiments, the height of the post 332 defines the distance between the lends 312 and the filter and iris control devices of the camera 200 (which are secured to the top of the post 332). The post 332 also includes a pair of threaded apertures 334 for securing the mirror housing 306 to the adaptor plate 304
The adaptor plate 304 is configured to be coupled to the bottom surface 108 of the camera housing 100. As such, the adaptor plate 304 includes a plurality of apertures 343 for receiving corresponding bolts or screws 344 to secure the plate 304 to the housing 110. The adaptor plate 304 also includes a pair of elongated apertures 346. The apertures 346 are useable to secure the lens assembly 302 to the adaptor plate 304 via the threaded apparatus 322 of the base plate 310 of the assembly 302.
As shown in FIGS. 10 and 13, the mirror housing 306 includes a housing 360 and a mirror support 362. The housing 360 includes a generally planar top surface 364 and bottom surface 366. The housing 360 also includes a pair of curved side walls 368, 370 and a substantially planar front wall 372. A window 374 is defined in the front wall 372. A cylindrical passageway 278 is defined through the housing 360 an includes an opening 280 defined in the side wall 368 and an opening 282 defined in the side wall 370. The mirror support 362 is illustratively embodied as a cylinder and includes a curved outer wall 384 (see FIG. 10). However, the mirror support 362 may have other shapes in other embodiments. The mirror support 362 includes a flat recessed area 386 defined in outer wall 364. A mirror 390 is positioned in the recessed area 386.
The mirror support 362 is insertable into the lateral passageway 278 of the housing 360.
