  • Intelligent driving safety monitoring system and method integrating multiple direction information
    Patent number: 7826964
    Abstract: An intelligent driving safety monitoring system capable of integrating multiple direction information is adapted to be installed in a vehicle. The system includes a first image capturing device, a second image capturing device, a data processing device, and an indicating device. The first image capturing device is used to capture a face image of a driver of the vehicle. The second image capturing device is used to capture a front lane image. The data processing device, after doing computations based on the face image of the driver and the front lane image, maps a sight direction of the driver and a mid-line of lane into a global coordinate space and integrates the same into multiple direction information. The indicating device outputs the multiple direction information to the driver for suggesting whether driving status of the driver is safe.
