AI Technical Summary
In existing technologies, laser rangefinders are sensitive to channel deformation and cargo thickness, resulting in inaccurate cargo storage depth detection. This is especially true for thinner cargo, where the laser path may misalign with the cargo surface, making it difficult to accurately reach the target.
A lidar is used for scanning. The lidar's scanning surface intersects with the bottom surface of the cargo channel to acquire point cloud data. By filtering point cloud data that meet the preset angle range and length threshold, the distance between the cargo and the lidar is determined, thereby calculating the cargo storage depth.
It improves the accuracy of cargo storage depth detection, reduces the impact of cargo channel deformation and cargo thickness on detection, lowers the possibility of missed detection and false detection, and uses detailed information from point cloud data to filter out interference from other structures.
