Description

Technical Field

Theodolite has some disadvantages when measuring displacement, mainly including the following aspects: cumbersome operation. Using theodolite to measure displacement requires a series of steps, including setting up the instrument, aligning the target, adjusting the angle, etc. These steps require a lot of time and manpower, and require operators to have certain professional skills, resulting in low efficiency; high cost: Theodolite is a relatively expensive measuring equipment, which requires a large investment of capital costs. The displacement measurement benchmark is not standard, and the installation position of the theodolite drifts. In addition, using theodolite to measure displacement also requires manpower and time costs. Utility Model Content
