| description | The utility model discloses a directional measuring device for a night precision control net, which comprises a prism body, a mounting rack and a laser pen, the mounting rack is arranged on the periphery of the prism body, the laser pen is arranged on the mounting rack, the axis of the laser pen is parallel to the axis of the prism body, and a locking assembly for locking the laser pen is arranged on the mounting rack. When the device is used, through light emitted by the laser pen, a target observation station can be searched through a laser beam, so that the target observation station can accurately find the prism body, the prism body can be illuminated to assist measurement, and compared with a traditional prism stop board, the mounting base and the laser pen are small in size and convenient to use. Therefore, the influence of wind resistance on the prism body can be effectively reduced, the prism body can be accurately aligned with the direction of an observation station, the qualified rate of measurement |
