System and method for identifying a camera pose of a forward facing camera in a vehicle

机译:用于识别车辆中的前置摄像头的摄像头姿态的系统和方法

摘要

A method includes capturing images of a vehicle driver's face from a driver facing camera and images of a forward road scene from a forward facing camera. The images are analyzed to derive gaze direction data in a vehicle frame of reference. The gaze direction data are statistically collated to determine a frequency distribution of gaze angles. One or more peaks in the frequency distribution are identified and associated with corresponding reference points in the images to determine one or more reference gaze positions in the vehicle frame of reference. The one or more reference gaze positions are correlated with a position of the reference points in a forward facing camera frame of reference to determine a camera pose of a forward facing camera in the vehicle frame of reference.
