The invention discloses a system and a method for accurately identifying a license plate of a smoky vehicle based on fixed snapshot, and relates to the technical field of environment monitoring. The system comprises an image acquisition module, an identification algorithm module, a snapshot algorithm module and a data analysis module. According to the invention, images in front of and behind a vehicle are acquired and analyzed; a snapshot area and a license plate identification area are set; close-up snapshot is performed on license plates in front of and behind the vehicle to obtain license plate images in front of and behind the vehicle; identification is performed; an identification result is output when license plate numbers are consistent; and when the license plate numbers are inconsistent, the license plate images in front of and behind the vehicle obtained by the close-up snapshot are identified and compared again until the license plate numbers are consistent, and the identification result is output. Therefore, the problem of inaccurate license plate information acquisition of a smoky vehicle at present is solved.

    一种基于固定式抓拍精准识别黑烟车车牌的系统和方法,涉及环境监测技术领域,包括:图像获取模块、识别算法模块、抓拍算法模块和数据分析模块,通过采集和分析车辆车前方和车后方的图像并分别设置抓拍区域和识别车牌区域对车辆前后车牌特写抓拍获取车辆前方和后方的车牌图像,并进行识别,在车牌号码一致时输出识别结果,在车牌号码不一致时,分别对特写抓拍得到的车辆前方和后方的车牌图像重新进行识别和比对,直至车牌号码一致并输出识别结果,解决了目前黑烟车车牌信息采集不精确的问题。
