Title: Method for panoramic scanning of space with an optoelectronic system
Inventor: Gajdenkov Andrej Viktorovich
IPC: G01S17/06
Filed: 2019-01-28
Granted: 2019-08-06
Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to the field of optoelectronic systems (OES) and can be used for panoramic viewing of space during observation with high angular resolution of objects characterized by considerable linear length, such as runways, automobile routes, sections of boundaries, etc. Disclosed method of panoramic view of space by optoelectronic system consists in formation of composite field of vision with the help of symmetrically located relative to centre of visual field of OES of three left and three right identical macrooptic video cameras with multi-element radiation receivers and various magnifications, wherein maximum magnification is provided by video cameras oriented at remote areas of the area of view of space, and minimum video cameras oriented to the centre of the area of view of space. At that, monotonous and non-breakable change of image scale is used throughout the field of vision of the OES which, for both right and left cameras, is approximated by a third-order curve. Elimination of differences in image scales at joints of adjacent video cameras is carried out by coordinate-dependent digital scaling, which aligns the magnification of the image along the stitching line for three video cameras located on the left and three video cameras located on the right side relative to the centre of the field of view of the OES. 
     EFFECT: formation of a panorama with monotonous and non-breakable change of image scale on the entire field of view of the OES, which is characterized by high angular resolution at the edges of the field of view of the space and low resolution in the centre of the field of view of the space.
