Research on Three-dimensional Measurement Method Based on Monocular Vision

3D measurement and reconstruction techniques are widely used in many fields, such as automated production, computer vision, and medical diagnostics. Fast and accurate three-dimensional reconstruction of the surface of the object for three-dimensional reconstruction is an important technical problem [1]. Based on the monocular vision measurement technology, this paper proposes a single-camera single-light source system for 3D reconstruction. The experiment uses a hemisphere of known radius to make the center of the hemisphere coincide with the target center. The circular target center is derived by the algorithm proposed in this paper and three-dimensional information of the location and error analysis.
