Description

A self-aligning laser tripod

technical field

The invention relates to a GPS measuring tripod, in particular to a laser self-centering GPS measuring tripod.

Background technique

In the process of GPS dynamic or static measurement, it is necessary to set up a tripod above the ground station, align the center of the base with the ground station, and fix the GPS receiver above the tripod to measure the coordinates of the station. Centering and leveling are two main links in the tripod erection process, which are divided into preliminary centering and leveling and precise centering and leveling. When the operator uses the naked eye to judge the initial centering and leveling of the tripod, often due to inaccurate visual inspection, the initial centering and initial leveling errors of the tripod are relatively large, resulting in repeated adjustments for accurate centering and leveling, and even It is time-consuming, labor-intensive and inefficient to repeatedly relocate the tripod. At the same time, when measuring the height from the base point of the tripod to the measuring point, it is usually measured manually with a tape measure, which has large human influence factors and increases the measurement error. In particular, in complex mountainous terrain, there is no traditional tripod installation condition near the measuring point or the centering and leveling cannot be achieved. When there are many measuring points, the rapid and accurate positioning of the measuring point is particularly important.
