SYSTEM AND METHOD FOR DAY AND NIGHT TIME PEDESTRIAN DETECTION

摘要

A pedestrian detection system implemented in a vehicle is disclosed. The system defines a Region of Interest (ROI) for a set of images based on resolution of each image and a region defined in the field of view of the vehicle driver; and determines a plurality of scanning windows in the ROI of each image. The system extracts Integral Histogram of oriented gradients (IHOG) features from each of the scanning window based on a feature vector length of a pre-defined dimension and detects the pedestrian based on the extracted IHOG features from each scanning window using a cascade of two or more classifiers. The cascade of two or more classifiers performs the detection based on ambient light conditions. Further when the pedestrian is detected, the system determines at least one foot point of the detected pedestrian.
