Abstract

During the operation of loading and unloading the containers by gantry crane, once the container is hoisted along with the truck, the container lock pin and the truck will be damaged, and more seriously, the container truck driver will be injured or die. In order to avoid this situation, this paper proposed an algorithm that combines two-dimensional point cloud analysis and image processing. First, the position of wheel in horizontal direction is determined by laser radar. Then the template matching algorithm of image processing is used to accurately detect and track the set container truck wheels. Finally, according to the displacement of wheels in the vertical direction to determine whether the truck is hoisted. Comparing with manual monitoring, photoelectric detection, regional sensor and laser radar detection, this method hashigher detection rate and shorter detection time. In the actual test, the experimental data confirmed this point.
