Abstract

The invention discloses a method and a system for adding a haze effect to driving scene video. The method is characterized by comprising the steps of acquiring haze-free clean driving scene video; calculating atmosphere radiance value information and a depth information matrix corresponding to each frame image in the driving scene video according to a dark channel prior based single-image defogging algorithm; acquiring a haze image model equation according to an atmospheric scattering model, and generating each frame image into a corresponding image with the haze effect according to the haze image model equation, the depth information matrix, the atmosphere radiance value information and preset haze concentration parameters; and synthesizing all of the images with the haze effect into the driving scene video with the haze effect. The method and the system disclosed by the invention realize quick addition of the haze effect to the driving scene video while ensuring good simulation effects, and is high in haze simulation confidence, fast in addition and easy to implement.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for adding haze effects to driving scene videos. Background technique [0002] With the development of computer image processing technology and the rapid improvement of visual sensor hardware technology, the development and application of vision-based advanced driver assistance systems (Vi-ADAS) are increasing day by day. In the past 30 years, the irrationality of my country's urbanization development and industrialization layout has led to serious deterioration of air pollution, and smog has become a high-occurrence pollution weather in most provinces and cities. Then, how to test the performance of Vi-ADAS in haze weather has become a problem that attracts the attention of researchers. Due to the poor visibility in foggy weather and the extremely low repeatability of environmental conditions, if traditional testing methods are used, not only will t...
