The invention discloses a parking lot crowdsourcing map generation method and device, equipment and a medium. The method comprises the following steps of acquiring crowdsourcing parking lot data acquired by each vehicle end sensor, performing track matching on vehicle tracks in the crowdsourcing parking lot data, and grouping the crowdsourcing parking lot data according to the obtained track matching degree, performing parking lot feature alignment on the crowdsourcing parking lot data in each group, and fusing the crowdsourcing parking lot data after the crowdsourcing parking lot data in each group are aligned, and generating a parking lot crowdsourcing map based on the fused crowdsourcing parking lot data. The technical problem that the generated crowdsourcing map is not complete and accurate enough due to the fact that collected map data is not complete and accurate enough in an area with weak GPS signals, especially an indoor parking lot, of an existing crowdsourcing map generation method is solved.
本申请公开了一种停车场众包地图生成方法、装置、设备和介质,方法包括:获取各车端传感器采集的众包停车场数据;对各众包停车场数据中的车辆轨迹进行轨迹匹配,并根据得到的轨迹匹配度对众包停车场数据进行分组;对各组内的众包停车场数据进行停车场特征对齐,并对各组间对齐后的众包停车场数据进行融合;基于融合后的众包停车场数据生成停车场众包地图。改善现有的众包地图生成方法在GPS信号较弱的区域,特别是室内停车场,会存在采集的地图数据不够完整和准确,导致生成的众包地图不够完整和准确的技术问题。
