Problems solved by technology

[0003] In view of the human error of high centering and high volume that will be introduced by the existing tripod frame, as well as the equipment such as the indoor rail mounting method and the bridge crane mounting method are too large and heavy, and cannot be moved, disassembled, assembled, and station cleaned The method is relatively simple, and the problem of multi-row and multi-column scanning cannot be performed. The first purpose of the present invention is to provide a three-dimensional laser scanner bearing lifting system

Abstract

The invention discloses a three-dimensional laser scanner bearing lifting system and an adjustment method for an optimal tilt angle thereof. The system includes a mobile vehicle structure and a three-dimensional laser scanner bearing lifting structure. The mobile vehicle structure includes a base, and the base is provided with moving wheels and a stable wheel assembly. The lifting structure of the 3D laser scanner includes a pneumatic lifting rod. The lower end of the pneumatic lifting rod is fixed in the center of the base. A platform is set on the top of the pneumatic lifting rod. There are three-dimensional laser scanners, and the automatic leveling base can adjust the tilt angle of the three-dimensional laser scanners. The system can lift the 3D laser scanner to a predetermined height by compressing the air with a manual air cylinder. It is simple to assemble, easy to move stations, and convenient for multi-station measurement. The lens tilt measurement of the 3D laser scanner collects point cloud data, which solves the problem of low data collection efficiency and low accuracy caused by the occlusion of scanning lines.

Description

technical field [0001] The invention relates to the technical field of carrying a three-dimensional laser scanner, in particular to a lifting system carrying a three-dimensional laser scanner and an adjustment method for an optimal inclination angle thereof. Background technique [0002] Traditional 3D laser scanner loading methods include tripod mounting method, indoor rail mounting method, bridge crane mounting method, etc. When using the traditional 3D laser scanner for measurement, the backsight orientation method is used similar to the measurement mode of erecting a total station. It is necessary to level the instrument and the target, and then measure the height of the instrument and the center of the target. Will introduce high human error on the neutralization amount. During the operation of the trolley equipped with the bridge crane system, it is inevitable that there will be dynamic attitude changes due to track defects. If this happens, the data of the changes ca...
