The invention belongs to the technical field of vehicle passing control, and particularly relates to a V2I-based priority passing method and system.The method comprises the steps that firstly, a vehicle owner registers and applies for a target vehicle license plate to an authoritative department, and a cloud server generates a digital watermark through a specific number and a digital signature and embeds the digital watermark into a vehicle license plate image; when the target vehicle travels to the roadside end shooting area range, the roadside end collects a vehicle license plate image and uploads the vehicle license plate image and roadside end data to the cloud server; the cloud server identifies and extracts a target vehicle license plate in the vehicle license plate image, and the extracted target vehicle license plate and the roadside end data are matched in pre-stored data to verify whether the target vehicle enjoys the passing authority on the corresponding one-way road; and the verification result is fed back to the target vehicle and the roadside end, so that the target vehicle has reverse priority on the one-way road. According to the invention, the digital watermarking technology is applied to the vehicle license plate, and the V2I vehicle networking technology is combined to realize the one-way lane priority reverse passage of the target vehicle.

    本发明属于车辆通行控制技术领域,特别涉及一种基于V2I的优先通行方法及系统,首先车辆拥有者向权威部门注册申请目标车辆号牌,云端服务器利用具体号码和数字签名生成数字水印嵌入车辆号牌图像中;目标车辆行使到路侧端拍摄区域范围时,路侧端采集车辆号牌图像并将车辆号牌图像和路侧端数据上传至云端服务器;云端服务器识别并提取车辆号牌图像中的目标车辆号牌,将提取的目标车辆号牌及路侧端数据在预先存储的数据中进行匹配来验证目标车辆在对应单行道上是否享有通行权限;并将验证结果反馈给目标车辆和路侧端,使目标车辆在单行道上逆向优先。本发明将数字水印技术应用于车辆号牌,并结合V2I车联网技术实现目标车辆单行道优先逆向通行。
