2results about How to "Fix inaccurate positioning" patented technology

This invention discloses a rapid prototyping system for porcelain insulators, relating to the field of porcelain insulator technology. It includes a workbench with a lifting assembly fixedly connected above it via a mounting bracket. An upper mold is fixed to the movable part at the bottom of the lifting assembly. A lower mold is fixed directly below the upper mold on the workbench. Vertical guide rods are provided at the four corners of the lower mold, with guide cones at the top (narrower at the top, wider at the bottom) and the same size as the guide rods at the bottom. Vertical through-type limiting tubes are provided at the four corners of the upper mold, with the inner wall of the limiting tubes slidingly fitting against the outer wall of the guide rods. Both the upper and lower molds are equipped with temperature control mechanisms, including heating grids and temperature sensors. The temperature sensors detect the temperature of the heating grids, and the power of the heating grids is controlled by a first control unit according to a preset temperature. The two first control units communicate in real time via a wireless communication unit to ensure that the heating grid temperatures are the same. The upper and lower molds and their heating grids are the same size. This invention allows for rapid preliminary shaping, accurate positioning, and uniform heating.

This application provides a method, apparatus, electronic device, and storage medium for location reliability processing. The method includes: first, acquiring first point cloud data; then, filtering the first point cloud data to reduce the number of points while maintaining shape features, to obtain second point cloud data; smoothing a first grid map to eliminate noise, to obtain a second grid map; then, calculating the matching degree of each current point based on the second point cloud data and the second grid map; obtaining the actual matching degree of each current point by multiplying by a preset coefficient, and calculating the root mean square error to obtain a second laser matching degree; finally, using the second laser matching degree as the robot's location reliability. This application can obtain more accurate location reliability.
