Patent EP-0318188-A2 (EP)
Inventor: SUBBARAO MURALIDHARA
IPC: G01C3/08
Filed: 1988-11-11
Abstract: The present invention concerns a method of determining the distance between a surface patch of a 3-D spatial scene and a camera system (1). The distance of the surface patch is determined on the basis of at least a pair of images, each image formed using a camera system (1) with either a finite or infinitesimal change in the value of at least one camera parameter. A first and second image of the 3-D scene are formed using the camera system which is characterized by a first and second set of camera parameters, and a point spread function, respectively, where the first and second set of camera parameters have at least one dissimilar camera parameter value. A first and second subimage is selected from the first and second images so formed, where the subimages correspond to the surface patch of the 3-D scene, the distance from which to the camera system, is to be determined. On the basis of the first and second subimages, a first constraint is derived between the spread parameters of the point spread function which corresponds to the first and second subimages. On the basis of the values of the camera parameters, a second constraint is derived between the spread parameters of the point spread function which corresponds to the first and second subimages. Using the first and second constraints, the spread parameters are then determined. On the basis of at least one of the spread parameters and the first and second sets of camera parameters, the distance between the camera system and the   surface patch in the 3-D scene is determined. Using the distance finding method of the present invention, depth-­maps of the scene are provided in real-time and in a computationally efficient manner. In addition, the present method is used to automatically focus the camera system and to generate improved-focus images.

Abstract: A dual-polarization geometry for printed-circuit antennas, in which two layers of radiating elements and corresponsing power dividers are provided, one set (400) of power dividers being disposed orthogonally with respect to the other (200), so as to enable reception of two signals with orthogonal senses of polarization. Either dual linear or dual circular polarization may be achieved through suitable selection of radiating elements. Alternatively, a quadrature hybrid may be coupled, either externally or as an integral part of the antenna, to enable dual circular polariza­tion. Various shapes and types of radiating elements (16b), having patches or slots, may be employed in the various layers. Fur­ther, a gridded radiating element, formed of a grid (300) wherein a metallization region is etched selectively to yield a plurality of metal strips (16a) disposed parallel to each other with a predeter­mined separation, may be used. This element, in contrast to known elements which employ solid metallization regions, finds particular application in dual polarization geometries, wherein two signals are received simultaneously, and enables improved performance over a wide bandwidth. The gridded element also is applicable to single-polarization geometries.
