Figure 6. The 3D point cloud reconstruction process for pig morphology. Raw point cloud data from multiple views are first preprocessed using pass-through filtering and downsampling to remove noise and reduce data volume. Next, point clouds from the left, top, and right views are generated and color-coded. These multi-view point clouds are then aligned through registration to produce a reconstructed 3D model. The point cloud data shown in Figure 6 were collected by the authors at Guojia Pig Farm, Longyao County, Xingtai City, Hebei Province, China. 3D: Three-dimensional.
