Abstract

The invention relates to the field of optical and computer technologies, and discloses an RGBD-based car driver state detection and identification system. The system integrates units such as an RGB color image sensor module, a time-of-flight (TOF) depth and grey image sensor module, a near-infrared transmitter, a microprocessor and the like; depth information obtained through a TOF sensor and RGBcolor image information are subjected to synthesis algorithm processing; driver identity and posture are identified and detected; a driving state of a driver in a cab is detected; and the car controlgestures of the driver are controlled. RGBD information in the cab is obtained by adopting a color image sensor and a depth image sensor, so that multiple information of a color three-dimensional image (R, G, B, X, Y, Z, C) is calculated out; and auxiliary functions of information collection, safety driving, man-machine interaction and the like are provided for the driver in the cab.

Description

technical field [0001] The invention relates to electronic circuit design, image software processing, computer graphics, optics and other disciplines, and applies the complex multidisciplinary interdisciplinary research results to the field of ADAS (Advance Driving Assistance System) for a new generation of smart cars. Background technique [0002] With the popularity and number of automobiles increasing, the industry generally has higher and higher requirements for the intelligence and safety of automobiles. Autonomous driving and assisted driving are becoming a standard in the automotive industry. The status monitoring and fatigue monitoring of the driver and passengers in the cockpit can effectively improve the safety of the car. At present, the electrical control in the car is mainly controlled by buttons. The non-contact gesture control and human-computer interaction are also a manifestation of the car's intelligentization, which can provide a more convenient control me...
