Description

Flash-saving 3D camera equipment and manufacturing method

Technical Field

The invention relates to the technical field of face recognition, in particular to flash-saving 3D camera equipment and a manufacturing method thereof.

Background

The 3D camera is used for obtaining the depth information of the target object, and the functions of 3D scanning, scene modeling, gesture interaction, face recognition and the like can be further realized according to the depth information. The 3D camera based on the structured light technology or the TOF technology is a 3D imaging device widely used at present, and has been widely applied to a plurality of fields such as televisions, robots, mobile phones, AR/VR, etc., and an object in a space is restored by using an image captured by the 3D camera, assuming that there is a simple linear relationship between the image captured by the camera and the object in a three-dimensional space: the matrix M can be regarded as a geometric model of camera imaging, parameters in M are camera parameters, a process of solving the parameters is called camera calibration, generally, the parameters are obtained through experiments and calculations, and calibration parameters of each 3D camera are different, so that the data are acquired and stored along with the 3D camera before the 3D camera is normally used, a small flash is usually added in a 3D camera module to store the parameters and other module information, which is collectively called calibration data herein.

In the traditional assembly mode, flash accessories are required to be added, the production cost is increased, and data are processed and controlled through the solid memory, so that subsequent maintenance and updating are not convenient, and therefore, the 3D camera equipment capable of saving flash and the manufacturing method are designed to solve the problems in the prior art.
