In order to improve the automation degree and container loading and unloading efficiency of quayside container cranes, an automatic container lock pin unloading method based on 3D point cloud data processing -was proposed. The target object is scanned by the line laser sensor to obtain the point cloud structure, and the optimized filtering algorithm is used to denoise the point cloud data. The actual test data shows that the algorithm can analyze the key point coordinates of the locking point cloud in about 2s, and the key point coordinates of the locking point cloud can be analyzed in about 1.5s. The center coordinates of the keyhole at the bottom of the container are analyzed left and right, and the accuracy of the analysis is 98%. It is proved that the scheme has certain advancedness and practicability, and provides ideas for the specific implementation of the fully automated quayside container crane.
