1 to 6, the anti-glare vehicle road sign and road lane identification device 10 according to an embodiment of the present invention includes a light irradiation unit 100, an image photographing unit 200, and a shape projection unit ( 300).
In the anti-glare vehicle road sign and road lane identification device 10 according to an embodiment of the present invention, when the driver in the vehicle traveling on the road, such as at night, when the field of view is not secured, only the headlamps In some cases, it is difficult to grasp the improvement of road and road lanes, but in order to solve this problem, it is a shape projection system that helps safe driving by shining high brightness light that reinforces the shape so that the road sign and the road lane can be seen more clearly.
The light irradiation part 100 is provided in the vehicle 2 to irradiate invisible light forward while driving. Light irradiation unit 100 is preferably installed on the upper side of the windshield in the vehicle (2).
The light irradiation unit 100 may irradiate a wide range of light to a road sign, a center separator, and a road lane by irradiating invisible light that is not visible to the driver of the opposite vehicle. Invisible light is a light having a permanent wavelength of wavelengths visible to anyone except visible light, and includes ultraviolet rays, infrared rays, and X-rays.
The light irradiator 100 may include a light emitting member 110 that irradiates at least one of infrared rays, ultraviolet rays, and X-rays so that the other vehicle driver is not visible.
The light irradiation unit 100 is most preferably to apply infrared light from the invisible light.
The light emitting member 110 is installed inside the case part 20 and is formed to irradiate infrared rays forward.
Although one light emitting member 110 is illustrated as being provided in the case part 20, it may be changed to be provided with two or more light emitting members 110.
When the headlamp of the vehicle 2 does not shed light on the road display panel 4 only by the downlight, when the upper light is operated, the light of the upper light obstructs the driver's view of the driving lane of the opposite lane, which limits its use. When used, there is a problem that causes a large accident. On the other hand, since the light irradiation unit 100 according to the present invention irradiates infrared rays, such as invisible light, it does not interfere with the driver's field of view even when reflected on the vehicle of the opposite lane, it can be freely produced without being limited to the light irradiation range Has the advantage.
The image photographing unit 200 is configured to photograph an image (reflected light) retroreflected from the road display panel 4 and the road lane 6 by the light irradiated from the light irradiation unit 100 while driving.
Retro-reflection (reflection) refers to the reflection that returns the irradiated light beam to the light source as it is, the light irradiated to the road sign 4 and the road lane 6 in the vehicle does not disturb the light irradiation unit 100 ) Is reflected to the side as it is.
The retroreflective material may be made of at least one reflective material of glass beads, micro prisms, and fluorescent materials. Of course, retroreflective materials can be applied to a variety of other reflective materials.
In particular, in the case of the road sign 4, the background color, symbols, or characters may be configured to attach a reflective sheet containing a reflective material or to apply a paint containing the reflective material to perform retroreflection. In the case of the road lane 6, the retroreflective principle may be applied so that the road lane 6 is clearly seen by separately attaching circular glass beads to the upper portion after applying the paint.
In this way, the retroreflective material contained in the road sign 4 and the road lane 6 imparts light of tens to thousands or more times of light, so that the infrared rays irradiated from the light irradiation unit 100 are further amplified and reflected. The infrared reflected light is captured by the image capturing unit 200.
Therefore, the image photographed by the image capturing unit 200 is captured more clearly than the road sign 4 and the road lane 6 other portions. As a result, since the image photographed by the image photographing unit 200 mainly photographs only the road sign 4 and the road lane 6, the shape projection part 300 to be described later is applied to the road sign 4 and the road lane 6. Only the road signs 4 and the road lanes 6 are clearly visible in the driver's field of view.
The image capturing unit 200 may include an IR camera 210 reflecting and photographing infrared rays emitted from the light irradiating unit 100.
The image capturing unit 200 is disposed in the case part 20 so that the photographing part faces forward.
Infrared camera 210 is by the retro-reflective material contained in the background color, letters, symbols and road lanes 6 of the road sign 4, while the infrared rays irradiated from the light irradiation unit 100 are hardly visible to the driver of the opposite lane. The reflected light is taken more clearly.
The infrared camera 210 may be disposed in parallel with the light emitting member 110.
The shape projection unit 300 transmits the image signal photographed by the image taking unit 20 while driving to project high-brightness light in the state overlapped with the shape of the road display panel 4 and the road lane 6, and thereby the road display panel 4. And the road lane 6 is clearly visible.
The shape projection part 300 receives the image signal of the infrared camera 210 in which the shape of the road sign 4 and the road lane 6 is clearly photographed, and overlaps the shape of the road sign 4 and the road lane 6 as it is. By irradiating as much as possible, the road sign 4 and the road lane 6 in the driver's field of vision at night may provide an effect of emitting bright light, thereby helping to drive safely. In particular, in the case of the road sign 4, it is desirable to have an effect that the letters, figures, symbols, etc. emit more light than the background color.
Since the shape projecting unit 300 has almost no time delay even when the vehicle 2 is traveling at a high speed, the image projecting unit 200 may be mounted on the road display panel 4 and the road lane 6 at the position where the light irradiation unit 100 irradiates. Since the light emitted from the shape projecting unit 300 through the shooting is irradiated to be superimposed as it is, the phenomenon in which the road display panel 4 and the road lane 6 are seen by the driver's eyes due to time delay does not occur.
The shape projector 300 may include a light emitting projector 310 which transmits and shines an image signal photographed by the image capturing unit 200.
The light emitting projector 310 is installed inside the case part 20 so as to irradiate infrared rays forward.
The shape projection unit 300 synchronizes with the screen angle of the image photographing unit 200 with respect to the movement of the road sign 4 and the road lane 6 when the vehicle 2 moves forward, left and right, and up and down. (4) and the movement of the road lane 6 are tracked so that the projections overlap the high brightness light in the shape of the road sign 4 and the road lane 6.
That is, since the light projected from the shape projection part 300 is only reflected on the road sign 4 and the road lane 6 while driving the vehicle, the glare of the vehicle driver driving in the opposite lane is prevented, and the driver makes the road sign and the road. Clear lane recognition can help you drive safely. In addition, since the light irradiated from the light irradiation unit 100 is invisible light such as infrared rays, the light is not visible to the driver of the opposite lane. Accordingly, the opposite lane driver can safely drive from the orphanage part 100 and the shape projection part 300.
Meanwhile, when the shape of the road sign 4 and the road lane 6 is blurred in the image photographed by the image capturing unit 200, the shape of the road sign 4 and the road lane 6 may be more clearly recognized. It may further include a shape recognition correction unit 400 to correct the image to be transmitted to the shape projection unit 300.
The shape recognition correction unit 400 uses a shape processing technology (image processing chain) when the ground color, letters or symbols (special characters) of the road sign 4, and the wear or part of the road lane 6 are damaged or partially damaged. To correct.
Accordingly, the shape recognition correction unit 400 restores the shape by using a shape processing program (image processing program) despite the background color, letters or symbols of the road sign 4 and the road lane 6 being blurred or damaged. By improving or improving, the driver can reinforce (correct) the letters or symbols of the clear road sign 4 and the road lane 6.
The light irradiator 100, the image capturing unit 200, and the shape projecting unit 300 may be integrally provided in the case unit 20.
As shown in FIGS. 1 and 2, the case part 20 is preferably installed at an upper end portion of the windshield of the vehicle 2. Of course, the case unit 20 may be fixed to a support on a roof of a vehicle or the like so that the light irradiation unit 100, the image capturing unit 200, the shape projecting unit 300, and the like may face the front.
The light irradiation unit 100, the image taking unit 200 and the shape projection unit 300 is preferably installed as close as possible. The light irradiation unit 100, the image taking unit 200 and the shape projection unit 300 is most preferably having a distance of about 1cm from each other. In particular, the light irradiation unit 100 and the image capturing unit 200 may be integrally formed so as to be close to each other.
The anti-glare vehicle road sign and road lane identification device 10 according to an embodiment of the present invention may further include a data storage unit 300.
The data storage unit 500 is configured to process and control the stored information to selectively irradiate the light in accordance with the weather conditions and road conditions in the high-brightness light irradiated from the shape projection unit 300.
For example, in the case where the data storage unit 500 is navigation, the information stored according to the road situation is fetched in the navigation and selectively controlled by the shape projection unit 400 to irradiate light, thereby allowing the driver to remotely control the vehicle. It is possible to additionally provide an identification capability of the road sign 4 at a short distance.
The shape projection unit 400 includes at least one of general driving information, left and right rotation information, side display information, dangerous area information, bad weather information including fog and rain, and road display upward display information stored in the data storage unit 500. In whole or in part, it may be controlled to irradiate light selectively.
Meanwhile, information such as general driving information, left and right rotation information, side display information, dangerous area information, bad weather information including fog and rain, and road display upward display information stored in the data storage unit 500 may be illustrated as an example. Depending on the various other information can be stored and used.
The data storage unit 500 may be embedded in the case unit 20 rather than the navigation, or may be separately installed and used inside and outside the vehicle.
The data storage unit 500, the light irradiation unit 100, the image photographing unit 200, the shape projection unit 300, and the shape recognition correction unit 400 are supplied with power through the power supply unit 600. The power supply unit 600 may be any one of a cigar jack, a vehicle battery, or a self power source.
