An ATR camera with adjustable focus position

technical field

The utility model relates to a surveying and mapping instrument, in particular to an ATR camera head whose focusing position can be fine-tuned.

Background technique

ATR (Auto Targets Recognition) is automatic target recognition, which refers to the technology that the servo total station (Motorizedtotal station) automatically aims at the target prism and measures through image recognition and servo system. The servo total station emits an infrared laser that illuminates the prism. After the laser reflected by the prism is split and converged by the lens of the telescope box of the total station, the photosensitive components generate digital signals. The digital signal is processed and amplified to form a prismatic picture. In order to present a clear image, it is necessary to place the photosensitive element near the focal plane of the optical path.

Due to the processing errors and installation errors of optical structural parts in different instruments, there are subtle differences in the focal plane of different instruments. Therefore, the positions of the photosensitive components of different instruments have different changes. The existing products realize the change of position by processing structural parts of different heights or using spring washers, which makes the structure complex, the cost is high, and the work efficiency is low.
