Method, device and equipment for determining elevation of parking lot map data

The invention provides an elevation determination method, device and equipment for parking lot map data, and the method comprises the steps: traversing all road lines and/or center lines in the parking lot map data, and obtaining to-be-assigned geometric points on each road line and/or center line; respectively determining the elevation of a geometric point to be assigned on each road line and/or center line; and smoothing the elevation of the geometric point to be assigned on each road line and/or center line, and obtaining the elevation average value of all the smoothed elevations, so as to determine the final elevation of the parking lot map data according to the elevation average value. Through the method, the user can quickly and accurately judge the position of the parking lot based on the elevation information of the parking lot map data under the condition of no floor information or wrong floor information, and the parking experience of the user is effectively improved. 本申请提供一种停车场地图数据的高程确定方法、装置及设备，其中，
