Mine card unloading point available state identification method, system and device and storage medium

The invention relates to the technical field of mine truck unloading, and discloses a mine truck unloading point available state recognition method, system and device and a storage medium, the system comprises a mine truck with a forward laser radar and a driving background, and the method comprises the steps that a forward route, a gear shifting point and a backward route in an unloading area are planned, the gear shifting point is a turning point from the forward route to the backward route, and the last point of the backward route is a preset unloading point; driving a forward route, scanning scene point cloud in real time by a forward laser radar, and removing ground point cloud to serve as retaining wall point cloud; converting the retaining wall point cloud into a global coordinate system for superposition; driving to a gear shifting point; and carrying out analysis according to the superposed point cloud, and identifying the availability of the preset unloading point. According to the method, the avail
