The invention relates to a crowdsourcing mode-based thrown object identification and early warning method and system, and the method comprises the steps: collecting data at a vehicle end through a driving vehicle, carrying out the identification of whether there is a thrown object or not based on the data, carrying out the target positioning and risk assessment of the thrown object, and uploading the information of the thrown object to a cloud end, and after the cloud end receives the information of the thrown object, carrying out the early warning of the thrown object. The method comprises the following steps: judging whether recorded thrown object information exists at the same position or not, if not, recording the thrown object information as newly found thrown object information, if yes, fusing the thrown object information with the recorded thrown object information, updating the thrown object information, and finally pushing thrown object early warning information to a terminal. According to the invention, a crowdsourcing mode is adopted, on the basis of crowdsourcing data and capability of a large number of vehicles, vehicle-mounted multi-sensor data of the large number of vehicles are utilized to carry out thrown object identification, and through cooperation with cloud information, iterative updating and publishing of thrown object information at accurate positions on a road are realized; therefore, accurate identification and early warning of the thrown objects on the road can be improved, the cost is reduced, and the safety of road driving is improved.

    一种基于众包模式的抛洒物识别及预警方法及系统,其在车端,通过行驶中的车辆采集数据,基于数据进行识别抛洒物是否存在抛洒物,并对抛洒物进行目标定位,风险评估,然后将抛洒物信息上传云端:在云端,接收到抛洒物信息后,先判断同位置是否存在已记录抛洒物信息,若没有就将抛洒物信息记录为新发现的抛洒物信息,若有就与已记录的抛洒物信息融合,并更新抛洒物信息,最后向终端推送抛洒物预警信息。本发明是采用众包模式,基于大量车辆的众包数据及能力,利用大量车辆的车载多传感器数据进行抛洒物识别,并通过与云端信息的协同,实现道路上精确位置的抛洒物信息的迭代更新与发布,这样可以提高对道路抛洒物的精准识别与预警,降低成本,提高道路行驶的安全性。
