The invention discloses a dynamic graph
convolution-based target
point cloud completion method for a battery replacement
robot, and the method comprises the steps: 1, reconstructing a complete target
fastener model from a multi-view image through SFM and MVS technologies, and obtaining complete
point cloud data; 2, constructing an incomplete-complete
point cloud pair as training data by using a geometric constraint-based adaptive
cutting strategy; 3, multi-resolution
point cloud processing is adopted, and
feature extraction and fusion are carried out according to three-level resolution; 4, on the basis of DGCNN dynamic graph
convolution, in combination with multi-stage Edge Conv dynamic edge
convolution and a
Transform coding module, local geometric feature capture and global relation
perception are realized; 5, point cloud generation adopts a
pyramid step-by-step refining method, geometric details are added to each layer based on a previous layer result, and the number of points is gradually expanded; and 6, the training process is guided through a multi-target joint
loss function, and the point cloud quality is improved while the precision is ensured. The geometric structure integrity of the point cloud of the target
fastener is improved, and the operation error of follow-up operation of the battery replacement
robot is reduced.
