Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to a three-dimensional reconstruction method based on object surface normal detection, a three-dimensional reconstruction device based on object surface normal detection, an object surface normal detection device and an object surface normal detection system. Background technique [0002] Usually, the world that people come into contact with is three-dimensional. Compared with the one-dimensional and two-dimensional data such as distance and angle, the three-dimensional data is closer to reality and can describe the object to be measured more completely. At present, 3D data has been widely used in various fields such as measurement and virtual reality, and is an important tool for understanding the environment and perceiving the world. Three-dimensional data needs to be obtained through three-dimensional reconstruction technology. The generalized 3D reconstruction refer...
