Real time double cameras provided pedestrian detection system for use under scotopic vision conditions

Abstract

The invention relates to the technical field of image processing, more particularly, to a real time double cameras provided pedestrian detection system for use under scotopic vision conditions. The system comprises a central processing unit, an infrared camera for acquiring infrared video images, a visible light camera for acquiring visible light video images, and an infrared image detection unit for detecting if a detected infrared image contains a human target in all to-be-chosen targets in the infrared image and determining the positions of the to-be-chosen targets without a human target in the infrared image. The system also comprises a visible light image detection unit for detecting a visible light image arising at the same time with the infrared image to see if there is a human target at positions in the visible light image identical to those positions of the to-be-chosen targets without a human target in the infrared image. According to the invention, in a detection area, a choosing module marks the to-be-chosen targets excluding a human target after infrared detection and further based on the determined positions of the to-be-chosen targets excluding a human target with corresponding positions in a visible light image, uses a visible light method to do further detections.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a dual-camera real-time pedestrian detection system under dark vision conditions. Background technique [0002] Humans are the most active element in the environment and the most in need of attention. Traditional video human object retrieval requires professionals to carefully review each frame of possible images, the accuracy cannot be guaranteed, and it takes a lot of time. As an important field of computer vision and pattern recognition technology, pedestrian detection technology is the best way to replace manual retrieval. Pedestrian detection has a wide range of applications, such as the monitoring of cars, train stations, airports and other scenes in public places; the pedestrian warning function in vehicle driving assistance systems, etc. [0003] The existing pedestrian detection directions are mainly divided into two types: one is to perform pedestrian detecti...

Problems solved by technology

Therefore, the use of pedestrian detection systems in infrared images has gradually attracted people's attention, but due to the lack of detailed information in infrared images, it is difficult to detect overlapping human targets

[0005] The existing technology generally uses a single infrared camera or visible light camera for pedestrian detection, but the missed detection rate is high and the real-time performance is poor. It is necessary to combine the advantages of infrared image detection and visible light image detection to design a real-time pedestrian detection system and method.
