Abstract
The application provides a kind of complex environment under image enhancement and passage cost chart generation method and system, applied to image processing technical field, the method obtains original environment image and standardization processing, based on local gray variance self-adapting determination cutting limit threshold, combined with brightness protection weight generation enhanced image;Extract boundary mutation, surface roughness, local contrast and shadow risk and other multi-response characteristics, determine candidate high-cost area and generate boundary uncertain response;Fusion generates pixel-level passage cost chart above-mentioned response, and combined with camera calibration parameter and posture information projection to ground coordinate system, output spatial passage cost chart and passage area result.The application can reduce the influence of complex illumination, shadow and texture change on passage area extraction, improve the continuity and stability of passage risk representation.
