Pig rib cutting path planning method based on 3D point cloud
The invention discloses a pig rib cutting path planning method based on 3D point cloud, and belongs to the technical field of intelligent cutting and robot automation. High-precision original point cloud of a rib area of a pig carcass is obtained in real time through a 3D visual sensor, and then a segmentation threshold value is dynamically adjusted by introducing a self-adaptive growth factor based on local point cloud density, so that the preprocessed point cloud is robustly and accurately segmented into rib and rib meat areas, and a centerline of a spine and a rib gap are synchronously positioned. And based on the segmentation result, a plurality of independent costal meat communication components are automatically identified and separated through voxelization clustering and graph theory connectivity analysis. For each component, the main extension direction of the component is determined by constructing an axis alignment bounding box, and a series of discrete path points closely attached to the actual surface of the point cloud are generated in the direction. Spatial fitting is carried out by utilizing a cubic polynomial curve to generate a smooth and continuous cutting path which is highly fit with an anatomical structure, and the cutting path is directly converted into an executable track of the robot.
