Laser Scanner Position Measurement Method and Accuracy Verification Based on Monocular Vision

The method of position measurement based on monocular vision has a wide range of applications in various fields. In this paper, a method based on monocular vision for laser scanner position measurement is proposed and implemented. It can be applied to the three-dimensional reconstruction of point cloud by combining visual positioning technology with laser scanner. Firstly, this paper studies and designs a 3D target (the 3D target is mounted on the laser scanner) made by using the infrared LED light-emitting diode as the control points. Then use the EPnP solution to solve the position of the laser scanner, including spatial position coordinates (x, y, z) and three Euler rotation angles (α, β, γ). The measurement method proposed in this paper is simple and easy to operate, and the experimental results show high measurement accuracy.
