背景技术： Background technique:
In geodetic surveys and engineering surveys, it is necessary to place the measuring instruments such as the theodolite, the level gauge, and the total station on the tripod. On the one hand, the measuring range of the instrument can be expanded, and on the other hand, the measuring personnel can operate the instrument. The existing tripod is also called a tripod.
The base has a flat shape, and a fixing member such as a vertical screw is arranged at the center of the base, and three legs are connected to the base, and the length of the leg and the angle between the leg and the base can be adjusted. When measuring, the measuring instrument is fixed to the base by screws or the like, and the length and angle of the legs are adjusted.
The reference plane of the measuring instrument coincides with the horizontal plane at the measuring point and the vertical axis of the measuring instrument coincides with the perpendicular line at the measuring point. The existing tripod has the following problems:
）由于测量仪器置于基座上而与地面测量标志点分离，测量时均需要费时费力的调整，才能保证测量仪器的竖轴与通过测量标志点的垂线重合，并且需要测量仪器观测基准面与地面标志点的垂直距离，这些环节增加了测量难度而降低了工作效率，且因误差源多而降低了测量的精确度。 ( 1
Since the measuring instrument is placed on the pedestal and separated from the ground measuring mark point, it takes time and laborious adjustment to ensure that the vertical axis of the measuring instrument coincides with the vertical line passing through the measuring mark point, and the measuring instrument is required to observe the reference surface. The vertical distance from the ground marker points increases the measurement difficulty and reduces the work efficiency, and reduces the accuracy of the measurement due to the large number of error sources.

(Global Positioning System for Global Positioning System) A columnar measuring facility that needs to stand upright on the measuring point, such as a pole, can only be operated by the surveyor. It is not only time-consuming and labor-intensive, but also difficult to ensure accurate leveling, thus reducing the accuracy of the measurement. .
