Analysis of a large number of traffic accidents showed that pedestrians are the vulnerable participants in traffic. In order to protect the safety of pedestrians, it is necessary to improve the intelligent level of vehicles, and assist the detection of pedestrians in danger of accidents through on-board terminals equipped with intelligent monitoring capabilities, so as to timely give early warning. The intelligent mobile video monitoring terminal with pedestrian detection capability has been designed based on the aggregated integral channel model to meet the needs of vehicle-mounted intelligent monitoring. A pedestrian detection algorithm based on the polymer integral channel model has been designed for multichannel video processing platform composed of TI DM365 chipset and TVP5158, and typical scene experiments were conducted. Experimental results showed that the terminal can implement remote video monitoring via mobile network, and effectively complete pedestrian detection, which improves the level of vehicle intelligence and traffic safety.
