In this thesis, we propose the idea to develop a real time rapid detecting pedestrians and measure the distance between vehicle and pedestrians based on laser scanner and camera data fusion for an unmanned ground vehicle system (UGV). The fast speed reflecting of laser’s beams provided an accurate range to compute the distance of any objects which appears in front. And image that captured from camera is used to classify shapes of object. First, laser scanner point data is clustered into segments, each of that indicates a candidate position of pedestrian. Then because of laser and image frames are different, Inverse Perspective Mapping (IPM) Algorithm is used to transform image plane into real world plan for matching with laser frame to form regions of interest (ROI) on the image. Once ROI is defined, Finally pedestrians could be extracted by using Support Vector Machine (SVM) classifier on Histogram of Oriented Gradient (HOG) features. The proposed system is tested on standard x86 machine and gives good real time performance.
