考虑视觉传达效果的夜视环境视觉定位方法研究
Research on vision locating method considering visual communication effect in night vision environment
摘要
Abstract
In night environment,the collected image is easily disturbed by the factor of nearby light due to its low con⁃trast,contains much interference noise,and the interference effect of vision expression isn’t considered,so a vision locating method considering visual communication effect in night vision environment is proposed to preprocess the image,and filter the noise in night vision environment. In the method,the reflection weak light image is acquired based on LOG filtering,the Gaussian filter is used for smoothing filtering of the target image,the Laplace filter is used to acquire the edge information of target image to improve the target identification degree. The target bright surface area is filled with the search line injection filling method, which can enhance the brightness vision communication effect of the target. The target positioning method based on luminance accumulation histogram is adopted to screen the target and determine the accurate location of the target according to the vision communication characteristics of target brightness,color,shape,etc. The experimental results indicate that the proposed meth⁃od is superior in each index for locating the vehicles in night vision environment,is applied to different environments,and has wide application range.关键词
