Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical measurement, in particular to a multifunctional prism. BACKGROUND

[0002] With the continuous improvement of total station technology, ATR automatic measurement and intelligent measurement have become more and more common. Total station ATR measurement needs to be completed in cooperation with a prism. The reflective sticker can only meet the needs of distance measurement and cannot be applied to ATR measurement. When the measured point is on the ground, the conventional prism can be used to achieve the measurement. However, when the measured point is on the side of a building, the prism can only be placed at the measured point by manual assistance. If the measurement period is long, multiple people are needed to complete the measurement, which not only consumes a lot of manpower, but also cannot completely keep still, resulting in poor measurement accuracy. In addition, because the conventional prism cannot completely match the measured point, a correction number needs to be added to calculate the relevant data to the measured point, making the subsequent calculation of the results more complicated and seriously affecting the work efficiency. SUMMARY

[0003] The present application provides a multifunctional prism. The prism part is connected to the matching device in a plug-in manner, and the prism is accurately centered on the target point by adjusting the centering of the cross differentiation line and the prism. The work efficiency is improved, and a single person can perform ATR indoor and outdoor measurement. In addition, because the target point data is directly measured, the step of calculating the correction in the later stage is saved, and the factors of human error are reduced.

One end of the mounting part is connected to a measurement target object. A cross differentiation line is provided at the center position of the other end of the mounting part, and the center position of the cross differentiation line corresponds to a target point of the measurement target object. The prism part is arranged in the gap provided between the mounting part and the limiting part.
