AI Technical Summary

Technical Problem

In high-dust environments, the laser beams of existing vehicle-mounted LiDAR are blocked and scattered by dust particles, resulting in noise in point cloud data and ranging deviations. The accuracy of material boundary recognition is insufficient, and the loading position calculation results do not match the actual material pile shape, affecting loading efficiency. Furthermore, the high-cost LiDAR is difficult to maintain and cannot adapt to dynamically changing automated operation scenarios.

Method used

By filtering the target operation segment trajectory of the target operation structure from the full-cycle operation trajectory of the target operation equipment, extracting the target global key coordinate points to generate the boundary point cloud of the operation material, and combining the associated constraints and equipment parameters to calculate the loading position information, the grid map data scanned by the lidar is replaced as the sole data source.

Benefits of technology

It improves the accuracy of loading position information calculation, solves the problems of inaccurate material boundary identification and data update lag, realizes efficient loading in automated operation scenarios, reduces equipment maintenance costs, and adapts to dynamically changing operation scenarios.
