[0002] Engineering surveying and mapping instruments are indispensable equipment in modern engineering surveying. In modern engineering, surveying and mapping instruments are widely used in various fields, such as construction, roads, bridges, mining, forestry, engineering planning and environmental research. They can be used to measure physical quantities such as distance, height, depth, angle and direction, as well as for mapping work such as topographic maps, cadastral maps, and architectural maps. The high precision and stability of these instruments make them an indispensable part of various engineering projects. Engineering surveying and mapping instruments are constantly developing and innovating, providing strong technical support for various engineering fields.

[0003] However, the existing surveying instruments need to use laser to find reference points on the ground before measurement, and the set-up surveying instrument needs to be moved to find points, which is very troublesome to operate and greatly reduces the surveying efficiency. For this reason, we propose a surveying instrument for engineering surveying. Utility Model Content
