Research on Pedestrian Detection Technology in Front of Vehicles Based on 3D Laser Scanner

With the development of laser technology, single and high-concentrated laser technology has developed from one dimension and two-dimension in the 20th century to today's application in the field of 3-dimension measurement; meanwhile, it achieved measurement with high precision and fast speed. In the wave of digital city construction, China has accelerated the pace of information construction; moreover, China has also made a new breakthrough in the acquisition of data and information. Based on the research on the working principle of 3-dimension laser scanner, the technology of pedestrian detection in front of vehicles was studied in this paper. Finally effective pedestrian detection system was designed. This system is quite capable of detecting pedestrians with different postures and different clothes.
