The invention discloses a data extraction and enhancement method and system for vehicle-road cooperation roadside sensing information. The method comprises the steps that roadside sensing information is acquired through roadside sensing receiving equipment, and vehicle position information is acquired through vehicle-mounted positioning equipment to form vehicle true value data; extracting vehicle information corresponding to the specified license plate as vehicle observation data, and performing timestamp alignment on the vehicle observation data and the vehicle true value data; after the timestamps are aligned, calculating various indexes of perception information quality evaluation; based on the roadside sensing information, taking a vehicle with a specified license plate as a target, and extracting target feature information of each frame; and inputting the target feature information into a pre-constructed perception information error model, predicting to obtain compensated target feature information, and replacing original target feature information in the roadside perception information with the compensated target feature information to complete enhancement of the roadside perception information. According to the method, the classification efficiency and the real-time performance of the roadside sensing information are improved, and the credibility of the roadside sensing information is enhanced.
本发明公开了一种车路协同路侧感知信息的数据提取与增强方法及系统,方法包括:通过路侧感知接收设备获取路侧感知信息,通过车载定位设备获取车辆位置信息形成车辆真值数据;提取指定车牌对应的车辆信息作为车辆观测数据,将车辆观测数据与车辆真值数据进行时间戳对齐;在时间戳对齐后计算感知信息质量评价的各项指标;基于路侧感知信息,以指定车牌的车辆为目标,提取每帧的目标特征信息;将目标特征信息输入预构建的感知信息误差模型中,预测得到补偿后的目标特征信息,将补偿后的目标特征信息替换路侧感知信息中原始的目标特征信息,完成路侧感知信息的增强。本发明提升路侧感知信息分类效率和实时性,增强了路侧感知信息的可信度。
