Three-dimensional driver identification system and method based on structured light

Abstract

The invention discloses a three-dimensional driver identification system based on structured light. The system comprises a facial feature information acquisition module and a driver identification hardware device, wherein the information acquisition module comprises a structured light infrared emitter, an infrared receiving lens and an RGB camera, and the driver identification hardware device comprises a three-dimensional image processor, an RGB image processor, a first data memory, a central processing unit, a CAN communication device, an Ethernet communication device and a second data memory. According to the method, the actively-emitted infrared structured light is utilized, the high-precision recognition performance is still kept in the dark environment, the restriction of the dark light use environment is avoided, the restriction of the strong light use environment is avoided by adopting the mode of combining the three-dimensional infrared image and the two-dimensional RGB image,and the recognition precision of a driver is improved to 99.8%; the two identification modes not only meet the use requirements of personal and family users, but also meet the use requirements of enterprises and other large customers, enhance the flexibility of products, and increase potential customers.

AI Technical Summary

Problems solved by technology

This method can effectively avoid the defects of limited communication space and excessive power consumption, but this scheme belongs to a passive image acquisition system, and its recognition degree is low in dark light environments (currently the highest recognition rate is about 90%), so it is only suitable for Fleet management or driver fatigue monitoring in the automotive aftermarket
