Problems solved by technology
[0003] However, in the prior art, there are problems in the combined use of scanning targets and prism components: there are many types of scanning targets, and the shapes and specifications of the connecting parts at the bottom of the targets are different, so they cannot be used in combination with prism components, resulting in the inability to carry out geographical coordinate systems with the same name.

The invention discloses a switching device for a target and a prism assembly. The switching device comprises a switching part and a base; the switching part comprises a locking part, a rotating ring and a limiting part; the target extends into the rotating ring from the opening, far away from the base, of the rotating ring; the locking block of the locking part locks the connecting rod of the target, the stability of the target is guaranteed, and the locking block can rotate along with the rotating ring, so that the size of the locking space is adjusted, and the locking space can conveniently match connecting parts of different specifications and shapes; after the connecting rod is locked by the locking block, the rotating ring is limited through cooperation of the limiting part connected with the base and a jacking piece arranged on the limiting part, it is guaranteed that the rotating ring cannot rotate, and therefore stable locking of the connecting rod is guaranteed; the lower end of the base is provided with a connecting part which is connected with the prism assembly, so that the target can utilize the centering and leveling functions of the prism assembly to realize layout of homonymous control points of a geographic coordinate system.
Description
technical field [0001] The invention relates to the technical field of targets, in particular to an adapter device for a target and a prism assembly. Background technique [0002] The rapid development of 3D laser scanning technology, the scanning point cloud data and its derivatives obtained through this technology provide new solutions for multi-field engineering projects. When 3D laser scanning technology is applied to landscape modeling, deformation monitoring and other fields, it is necessary to The scanned point cloud in the scanning coordinate system is transformed into the geographic coordinate system through the control points with the same name, and most of the existing scanning targets on the market do not have the functions of centering and leveling (that is, the center of the target and the control point of the same name located on the same vertical line), therefore, in practical applications, the target needs to be used in conjunction with a prism assembly (suc...
