METHOD FOR ANISOTROPIC RECORDING OF THE LIGHT FIELD AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2023 - IPC G01S17/06 

FIELD: optics.

SUBSTANCE: invention relates to methods and methods for optical observation, more specifically, to optical methods for obtaining and processing optical information, detecting and locating objects in three-dimensional space by an optoelectronic system in one frame and with one exposure allowing determining the geometric characteristics, coordinates thereof, and distance thereto. The substance of the invention consists in the anisotropic generation of a flat image in the plane of a matrix photodetector with a different information structure of single pixels and groups of pixels in the meridional and sagittal planes using different sizes of linear photodiode sets horizontally (rows) and vertically (columns) in the photodiode matrix. Two images of the area of the observed space with objects of observation and an image of a two-dimensional or a three-dimensional depiction of the objects are obtained in the plane of one photodetector of the apparatus. Based on the resulting digital file, a set of low-resolution images is algorithmically determined in the meridional plane, said set being supplemented with signals from the photodiodes located in the sagittal plane; then, based on the analysis of the functions of gradient of the boundaries of the objects of observation, the missing information of the image points corresponding to the brightness matrix elements in the meridional plane is recreated, providing a possibility of obtain geometric information in a flat image of the objects in layers of the space at a preset distance with the maximum degree of accuracy. The objects, the coordinates and geometric characteristics thereof are identified by algorithmic processing of the images at a preset distance.

EFFECT: higher accuracy of determining all coordinates and geometric characteristics of objects.
