Patent ID: 10664997

Abstract:
The invention is a method for camera misalignment detection by means of processing images of a camera fixed to a vehicle and having a field of view containing a vehicle image area (11) imaging a portion of the vehicle and a remaining area (12), wherein in said processing step a plurality of reference locations (21) within an input image are used, said reference locations (21) being determined as edge locations along a boundary of the vehicle image area (11) in a reference image, and said processing step comprises checking at the reference locations (21) within the input image whether said reference locations (21) are edge locations by ascertaining at each reference location (21) whether a magnitude of an image gradient is above a gradient threshold limit, and alerting misalignment depending on an ascertained subset of the reference locations (21) where the gradient threshold limit is not reached. The invention also relates to a camera system, a computer program product and a computer-readable medium embodying the method.
