Vehicle-mounted pedestrian recognition system based on thermal imaging and radar

Abstract

The invention discloses a vehicle-mounted pedestrian recognition system based on thermal imaging and radar, and the system comprises an infrared thermal imager which comprises an infrared lens, an infrared detector and an image processor, the infrared lens is disposed at the front end of a vehicle body and is electrically connected with the infrared detector, and the image processor is electrically connected with the infrared detector; the input end of the image processor is connected with the output end of the infrared detector, and the output end of the image processor is electrically connected with the audio-video module; the radar sensors are arranged on the two sides of the vehicle body, and the radar sensors are electrically connected with the central processing unit. The infrared thermal imager is used for collecting and processing images to obtain pedestrian images, image information is displayed and broadcasted in the video and audio module in the vehicle, meanwhile, the radar sensor is used for sensing pedestrian information on the two sides of the vehicle body, and the central processing unit judges whether the distance between the pedestrian and the vehicle is dangerous or not. When danger occurs, display and broadcast can be carried out, pedestrian information at night can be effectively recognized, the driving safety of night driving is improved, and traffic accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of driving assistance products, and more specifically relates to a vehicle-mounted pedestrian recognition system based on thermal imaging and radar. Background technique [0002] Traffic safety is a major focus issue in today's society. It has attracted the attention of governments and societies in various countries, and it is also a major issue that intelligent transportation systems should strive to solve. When driving at night or in an environment with poor vision, the driver cannot effectively observe the passers-by in front and on both sides. When the passerby is found in a dangerous area, the driver often cannot make timely and effective countermeasures, resulting in a car accident. [0003] Therefore, how to provide a driving assistance product that can timely grasp pedestrian information and take early warning or preventive measures at night or in an environment with poor vision has become a technica...
