The invention provides a highway cloud toll collection method and system, and the method achieves the centralized processing and storage of data through transferring the core function of a toll collection system to a cloud end, thereby improving the toll collection efficiency and accuracy, and is specifically characterized in that an identification image block of a target toll collection vehicle is determined; processing the color gradual change loss amount at the image edge transition zone in the identification image block to obtain a gradual change harmonic image block, and obtaining a plurality of license plate identification points of the target toll vehicle through the gradual change harmonic image block; determining an identification feature vector corresponding to each license plate identification point; and performing cloud charging on the target charging vehicle according to the confidence license plate codes determined by all the identification feature vectors. According to the scheme, based on the confidence license plate code, cloud toll collection of the target toll collection vehicle can be realized when the license plate code is interfered by color gradual change of the edge transition zone, so that the accuracy of highway cloud toll collection is improved, and optimization and upgrading of a highway networking toll collection system are facilitated.
本申请提供了一种高速公路云收费方法及系统,通过将收费系统的核心功能迁移到云端,实现数据的集中处理和存储,从而提高收费效率和准确性,具体方案是确定目标收费车辆的标识图像块,由标识图像块中的图像边缘过渡带处的色彩渐变损失量处理得到渐变调和图像块,通过渐变调和图像块得到目标收费车辆的多个车牌标识点;确定各个车牌标识点对应的标识特征向量;根据所有标识特征向量确定的置信车牌编码对目标收费车辆进行云收费。上述方案基于置信车牌编码,可在车牌编码受边缘过渡带的色彩渐变干扰下实现对目标收费车辆的云收费,从而提高高速公路云收费的准确性,便于高速公路联网收费系统优化升级。
