Problems solved by technology
[0003] At present, due to the small size and insufficient rigidity of the metal bracket of the miniaturized 3D structured light face recognition module, it is prone to slight deformation during the process of assembling and fixing it to the device, and the expansion of the bracket due to the high temperature during use will also cause deformation. , and if the deformation of the bracket exceeds 0.01mm, it will cause the dislocation of the original calibrated graphics and result in the failure of face recognition. The greater the deformation, the higher the probability of failure. Therefore, the present invention designs an enhanced miniaturized 3D structured light face recognition model A device with group precision to solve the problems existing in the prior art

The invention discloses a device for enhancing precision of a miniaturized 3D structured light face recognition module. The device comprises a metal support, a floodlight source is arranged in the middle of the metal support, a distance sensor is arranged on one side of the floodlight source, the floodlight source and the distance sensor are both pasted on the metal support through back glue, and an infrared transmitter is arranged on the side, away from the floodlight source, of the distance sensor. According to the invention, the metal support, the stainless steel sheet and the locking screw are installed, and positioning and fixing are carried out through the hole of the stainless steel sheet and equipment, so that the metal support is prevented from being stressed and deformed, and the situation that in the assembling process, the metal support is stressed unevenly, so that the metal support is prone to slight deformation, and consequently face recognition fails is avoided; and then the face recognition degree is improved, the operation difficulty of assembly and maintenance is reduced, and the size of the real space of the recognition module is reduced to the greatest extent by performing integral installation through the integration mode.
Description
technical field [0001] The invention relates to the technical field of face recognition, in particular to a device for enhancing the accuracy of a miniaturized 3D structured light face recognition module. Background technique [0002] 3D structured light is an emerging biometric method, which includes patterns of points, lines, and surfaces, and refers to the type of light projected. Generally speaking, the network structure composed of multiple vertical bidirectional lines is the most commonly used, because this mode can realize three-dimensional contour measurement without scanning, and the speed is fast. The latest technology is used in the process of data capture, transfer and processing. Completely reform the process and efficiency of face recognition. [0003] At present, due to the small size and insufficient rigidity of the metal bracket of the miniaturized 3D structured light face recognition module, it is prone to slight deformation during the process of assemblin...
