Building construction safety information management method and system

The invention relates to the technical field of image processing, in particular to a building construction safety information management method and system. The method comprises the following steps: performing local gray difference analysis on the edge of a filtered image after filtering a gray image of a construction site to obtain a contrast index; determining a shadow area through the local gray level change of non-edge points in the filtered image, and obtaining a shadow diffusion degree index according to the gray level area and position distribution comprehensive analysis of the shadow area; filtering indexes are obtained through a contrast index and a shadow diffusion degree index, all filtering indexes are obtained and an optimal filtering image is determined under high-pass filters of all sizes corresponding to the construction site gray level image, and finally the optimal filtering image is optimized to be compressed, transmitted and stored. According to the method, image data with higher redundancy
