FIELD: transport.
SUBSTANCE: proposed detector (1) serves to detect solid objects at periphery of vehicle (V). Note here that said detector (1) comprises frame grabber chamber (10). Said frame comprises detection areas (A1, A2) set in adjacent lanes behind the vehicle (V). Solid object evaluation module (33) is intended for evaluation if solid object stays or no in the frames of detection areas (A1, A2) grabbed by camera (10). Crosswise position detection module (34) serves to detect spacing (∆y) between vehicle position in the lane the vehicle (V) moves in and separation line separating said lanes. Module (33b) of setting the areas for request for increase in the size of detection area (A1 or A2) on the side of separation line location by larger magnitude in compliance with increase in distance (∆y) to separation line detected by crosswise position detection module (34). Lane change detection means (35) reveals the change in the vehicle motion lane. In case said lane change is revealed, smaller increase is used at size increase in predefined area outward in direction of vehicle width.
EFFECT: higher accuracy of detection.
