The application can realize the automatic denoising segmentation and extraction of a point cloud file scanned by a laser after the point cloud file is imported into an algorithm, and can segment the workpiece element according to the characteristics of the composite material, mark the belonging element into the belonging information of each point, and facilitate the extraction and calling.

This utility model relates to the technical field of depletion device modules, and discloses a key module of a depletion device, including a shell, bolts on the inner side of the shell, and two discharge plates on the top of the bolts. The two discharge plates are respectively designated as a first discharge plate and a second discharge plate. The first and second discharge plates are basically concave in shape, and the lower end of the concave body is provided with a flat surface with a flat area of ​​not less than 40 square millimeters. In this utility model, by adopting a concave structure for the first and second discharge plates and providing a flat surface at the lower end, with the flat surface being relatively parallel and having a flat area of ​​not less than 40 square millimeters, the unique shape is used to change the electric field distribution path. During normal energization, the current is conducted through the discharge plates. The flat surface expands the current-carrying area, while the concave structure allows the electric field lines to spread more evenly throughout the entire area. The uniform electric field distribution significantly reduces the problem of local overheating caused by electric field concentration.
