Abstract

According to the street obstacle recognition method in the typhoon scene based on the unmanned patrol car system, the ground segmentation algorithm and the DBSCAN algorithm are combined, meanwhile, data fusion is carried out on the edge features of the obstacles and the movement areas of the obstacles, and by judging the residence time of the target features in the movement areas, the obstacle judgment precision is greatly improved; the method has good robustness, can greatly improve the efficiency while guaranteeing the precision, and reduces the judgment time. With the adoption of the method, the unmanned patrol car can intelligently identify the obstacles in a typhoon environment, so that the road traffic capacity of rescue and relief personnel after the typhoon is greatly improved, and the personnel injury risk is reduced. Moreover, the patrol efficiency of the unmanned patrol car is further improved, the time cost is saved, the labor cost is reduced, and the difficulty of rescue work is reduced.

Description

technical field [0001] The invention belongs to the technical field of unmanned patrol car control, and in particular relates to a street obstacle identification method in a typhoon scene based on an unmanned patrol car system. Background technique [0002] Typhoons bring sufficient rainwater to vast areas and become a rainfall system closely related to human life and production. However, typhoons always bring various damages. Its destructive power is mainly composed of strong winds, rainstorms and storm surges. It is one of the most serious natural disasters in the world due to factors, and has the characteristics of strong suddenness and great destructive power. At present, the assessment and treatment of typhoon disasters in large coastal cities are mainly through manual inspection of the typhoon in the jurisdiction after the typhoon comes. Streets, downed trees, billboard obstacles were found and registered, and then cleaned up. Generally speaking, the efficiency of man...
