Abstract
In order to overcome the shortcomings of traditional vision methods in the field of vehicle driving assistance, include visible light imaging system is vulnerable to the influence of illumination conditions and small field of view (FOV) imaging system has a large blind area, this paper proposed an environmental perception method based on ultra-wide FOV infrared imaging system. However, due to the compression of the Ultra-wide FOV infrared lens, the target occupies fewer pixels, and the detection distance is greatly limited. Therefore, this paper studies the feasibility of the application of Ultra-wide FOV infrared imaging system in the vehicle auxiliary driving system from the road objectives imaging size. Firstly, the general model of fisheye camera is used to build the imaging model of the Ultra-wide FOV infrared camera. Then, the vehicle driving safety distance and pedestrian imaging size characteristics are analyzed. Then the pedestrian detection distance of the Ultra-wide FOV infrared imaging system is simulated theoretically. Finally, a set of Ultra-wide FOV imaging system, which the FOV is 143° × 106° FOV and the detector resolution is 800 × 600, is used to carry out the experiment. The experiment shows that the pedestrian detection distance of the system proposed in this paper is more than 100 m, which can meet the needs of assistant driving at medium and low speeds.
