Equipment detection visible range analysis method

The invention provides an equipment detection visual field analysis method, and relates to the technical field of equipment visual field analysis, and the method comprises the steps: determining the number of detection sight lines and the direction of each detection sight line through a preset algorithm with equipment as an original point based on a preset DEM resolution and an equipment detection radius; within a theoretical maximum detection distance corresponding to a preset detection height, obtaining the maximum detection distance of each detection sight line through searching, and calculating position coordinates of a critical point corresponding to the maximum detection distance; connecting the critical points of the detection sight lines to form a plane, and obtaining an equipment detection area range corresponding to a preset detection height; within a preset detection distance, the maximum detection critical sight slope of each detection sight is obtained through searching, and therefore the equipme
