Abstract

The invention discloses a pedestrian early warning system based on a vehicle-mounted infrared image and a working method thereof. The system comprises an image acquiring unit, an image processing unit, a decision output unit, a driver early warning unit and a driver alarming unit, wherein the image acquiring unit, the image processing unit and the decision output unit are sequentially connected in parallel; the image acquiring unit is connected with a vehicle-mounted infrared camera to acquire infrared image information and transmits the information to the image processing unit to be processed; and the decision output unit transmits a signal to the driver early warning unit or the driver alarming unit according to the current vehicle speed information of a vehicle. On the pedestrian cutting technology, k-means Cluster Analysis algorithm is adopted to acquire a relatively accurate pedestrian interest area, so that the next step of identifying pedestrians is simple, and a part of non-pedestrian interference is avoided. A pedestrian identifying method of a serial combination way is adopted in a pedestrian identifying process, so that the accuracy of pedestrian detection is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile active safety, relates to an image processing method and pedestrian safety protection knowledge, and in particular to a pedestrian early warning system based on a vehicle-mounted infrared image and a working method thereof. Background technique [0002] At present, traffic accidents caused by collisions between vehicles and pedestrians occur frequently, which poses a great threat to the safety of people's lives and properties. Pedestrian detection is a key technology and a necessary technology in the assisted driving system of vehicles. It can promptly inform the driver of the existence of pedestrians in front of the vehicle, and perform safety warnings to reduce or avoid collisions between vehicles and pedestrians. It has potential economic value and wide-ranging application prospects. Ordinary cameras based on visible light cannot obtain proper video output images when the visible light sour...
