摘　　要：视频图像质量是衡量闭路电视监视系统好坏的关键技术指标。图像质量评价方法分为主观评价和客观评价,客观评价依据对原始参考图像信息的依赖程度,可分为全参考评价方法、半参考评价方法和无参考评价方法三种。国外研制出提供五分制客观评价功能的视频图像质量分析产品,但与公路行业实际要求还存在一定差距。模拟人眼主观评价方式且兼顾模拟/数字监视系统的无参考评价方法,是未来图像质量评价技术发展的主流方向。Video image quality is the key technical index to measure the quality of CCTV monitoring system. Image quality evaluation methods are divided into subjective evaluation and objective evaluation. According to the degree of dependence on the original reference image information, the objective evaluation method can be divided into three types: full reference evaluation method, semi reference evaluation method and non reference evaluation method. The foreign developed video image quality analysis products that provide five score objective evaluation function, but there is still a certain gap with the actual requirements of highway industry. The non reference evaluation method, which simulates the subjective evaluation of human eyes and takes into account the analog/digital monitoring system, is the mainstream direction of image quality evaluation technology in the future.
