Method, system and equipment for measuring width of slow road

The invention discloses a method, a system and equipment for measuring the width of a slow road. The method comprises the following steps: acquiring a to-be-measured picture; a small sample instance segmentation model based on FGN is adopted, the to-be-measured picture is detected and divided, a plurality of mask matrixes are generated, and each mask matrix identifies a slow road area and an area type; counting the pixel width of the slow road area in each mask matrix line by line, and averaging the plurality of pixel widths to obtain the average pixel width of each slow road area; calculating the actual width of the slow road area according to a pixel width and actual width scale and the average pixel width; wherein the proportional scale of the pixel width and the actual width is the ratio of the average pixel width of the reference object to the standard width. The method can accurately measure the width of a road with a certain attribute, and is not limited to the distance between lane lines. 本发明公开一种慢行道路宽
