Problems solved by technology

Due to the weak data processing capability of ARM, and the video processing algorithm involves a large amount of data calculation, if the ARM chip is used alone to complete video data processing, the real-time performance of video processing cannot be guaranteed
When the video resolution is high and the amount of data is large, the ARM chip will n

Embodiment 1

[0093] Example 1: Monocular infrared video vehicle pedestrian detection tracking early warning system applied to trucks

[0094] The infrared camera 11 is installed on the grid of the truck, and the height h of the infrared camera 11 from the ground and the pitch angle, that is, the installation angle α, are measured. The infrared camera 11 is connected to the embedded module containing the image processing function through the BNC interface. The embedded module realizes the frequency preprocessing of the infrared image signal, filters the noise and enhances the graphics, and detects pedestrians and vehicles according to the detection characteristics. , and through the tracking algorithm to further confirm the target pedestrians and target vehicles, exclude false targets, according to the measured height h and pitch angle α of the infrared camera 11, use the ranging algorithm for vehicles and pedestrians, and obtain the distance of each target The distance, and the collision t...

Abstract

The invention discloses vehicle-pedestrian detecting, tracking and early-warning device and method. The method includes that the early-warning device preprocesses infrared videos obtained by an infrared camera through an image preprocessing module, detects vehicles and pedestrians through a detecting module, forecast-tracks the vehicles and pedestrians through a tracking module to eliminate interference influences of vehicle vibration and virtual targets, calculates the distance between each target and the infrared camera according to corresponding relationship between world coordinates and image coordinates through a distance measuring module, judges an early-warning standard through a judging module, and displays the infrared videos carrying target identifiers and distance information on a display. The vehicle-pedestrian detecting, tracking and early-warning device has the advantages that driving safety is improved, most traffic accidents are effectively avoided, and life and property loss is lowered. The invention further discloses the vehicle and pedestrian detecting, tracking and early-warning method using the early-warning device.

Description

technical field [0001] The present invention relates to an auxiliary safety driving system for automobiles, in particular to a vehicle pedestrian detection and tracking early warning device and early warning method based on monocular infrared video, which can be specifically applied to the fields of vehicle-mounted night vision, transportation, video monitoring and public safety, etc. object detection, tracking and ranging. Background technique [0002] With the rapid development of the automobile market and the increasing awareness of security, people have higher and higher requirements for automobile safety protection technology. The disadvantages of the existing automotive lighting system, such as short sight distance and poor effect at night, snowy weather or heavy fog, have become one of the hidden dangers of driving safety. In addition, when driving at night, drivers are usually caught by the other Vehicle lights interfere with blind spots and are prone to car acciden...
