This invention relates to the field of hydraulic press technology and discloses a hydraulic press device for producing metal trash cans, including a main body with four positioning rods fixedly connected to the top of the main body. When the arc-shaped plate continues to press the top of the can and rotates, it provides guiding friction to the can body. At this time, the metal area at the top of the can body is bent and shaped as the arc-shaped plate rotates. When the can body pushes the arc-shaped plate upwards, the arc-shaped plate pre-presses the metal at the top of the can body. Then, when the arc-shaped plate drives the metal of the can body to rotate and curl the edge, it enhances the curling force while reducing the likelihood of cracks appearing in the metal body during the curling process. By assisting in increasing the curling strength of the metal body, the arc-shaped plate further improves the integrity of the curling angle and increases the curling efficiency.

The present invention discloses a method and device for evaluating the accuracy of a point cloud map, and relates to the field of computer technology. A specific implementation of the method includes: S101, selecting a feature object on a point cloud map; S102, obtaining the coordinates of the feature points of the feature object in the real world to generate a feature point coordinate map; S103, selecting at least two real feature points on the feature point coordinate map, and determining the point cloud feature points corresponding to the at least two real feature points on the point cloud map; S104, calculating the real distance between the real feature points selected on the feature point coordinate map, and calculating the point cloud distance between the point cloud feature points selected on the point cloud map; S105, evaluating the accuracy of the point cloud map based on the distance difference between the real distance and the point cloud distance. This implementation reduces the manpower and time required to measure feature edges, and improves the reliability of the accuracy of the point cloud map.
