The existing auxiliary methods include AR virtual display technology, which scans the construction environment through equipment and models the scene after construction, so that people can adjust the construction site by wearing AR glasses. However, the existing construction auxiliary devices still have the problem of mobility.

[0003] For example, a scanning and photogrammetry device using AR with publication number CN210664463U can ensure that the two cameras move forward and backward at the same time when adjusting the camera distance through the set sleeve, guide rod 1, guide rod 2, support plate 1, support plate 2 and gears, thereby ensuring that the adjusted distances of the two cameras remain equal, and there is no need to calibrate them one by one, which reduces the adjustment time and is conducive to quick operation and use. In addition, through the set base plate, bracket, clamping ring, support rod, screw, counterweight, sleeve and ball, it can quickly perform horizontal correction during installation to ensure that the scanning and measurement results of the equipment are consistent with the entity, avoid angle errors, and ensure the accuracy of the scanning and measurement results.
