Image acquisition mode of the CMOS sensor is active, charge photosensitive diode of the output by direct amplification transistor. Moving object scale change and deformation; moving target in the tracking process or rotary motion, change and camera distance and perspective, will cause the target image scale change and deformation. In this paper, with a pedestrian movement target specific, statistic of pedestrian is based on pedestrian detection and segmentation. The paper presents Using CMOS Image Sensor to Design of Detection and Statistical Pedestrian in Motion Target. Experiments show that these technologies have achieved good results.
