The invention discloses an urban road material stock accounting method. The method comprises the following steps: acquiring road network data and night light images in a to-be-accounted area; generating a road network skeleton in the to-be-checked area according to the road network data; generating a road night grating image of the to-be-checked area according to the road network skeleton and the night light image; determining a road area estimation value in the to-be-checked area according to the road night grating image; and according to the material strength and the road area estimation value, calculating the urban road material stock of the to-be-calculated area by adopting a method from top to bottom. According to the method, the urban road material stock is constructed based on night light data to calculate the material stock of the urban road system, the urban road material stock is calculated by combining road network data and a bottom-up material flow analysis method, and the problem that complete statistical data of the system is lacked is solved to a certain extent.
本发明公开了一种城市道路材料存量核算方法,包括以下步骤:获取待核算区域内的道路路网数据和夜间灯光影像;根据所述道路路网数据生成所述待核算区域内的道路网骨架;根据所述道路网骨架和所述夜间灯光影像生成所述待核算区域的道路夜间光栅影像;根据所述道路夜间光栅影像确定所述待核算区域内的道路面积估算值;根据材料强度和所述道路面积估算值,采用自上而下的方法核算出所述待核算区域的城市道路材料存量。本发明基于夜间灯光数据构建城市道路材料存量核算城市道路体系的材料存量,结合路网数据和自下而上的物质流分析方法来核算城市道路材料存量,一定程度上解决了缺乏系统完整的统计数据的难题。
