摘　　要：目前高精度地图仍采取半自动交互形式制作,因此控制与评价高精度地图质量显得尤为重要。根据高精度地图制图规范、产品规格书等开发地图要素检查系统,可实现部分自动修正功能。依据空间拓扑关系与要素逻辑检查,设立三级检查机制,实现程序自动查、改、报错等功能,并根据错误要素重要性修改占比自动计算地图品质率。经杭州亚运会测试场与德清测试场实验可知,该方法可极大地提高审图效率,客观、公正地评价地图的品质率;其建立的检查机制模型不仅为地图从业者提供了借鉴方法,也为国家确立地图相关评价规范提供了参考。At present,high definition(HD)map is still made in the form of semi-automatic interaction.It is particularly important to control and evaluate the quality of HD map.In this paper,we used HD map drawing specifications and product specifications to develop a map element in-spection system,which could realize some automatic correction functions.According to the spatial topological relationship and element logic in-spection,three-level inspection mechanisms were established to realize the functions of automatic program inspection,correction and error report-ing,and automatically calculate the map quality rate according to the proportion of importance of wrong elements.The experiments of Hangzhou Asian Games test field and Deqing test field show that this method greatly improves the efficiency of map review,and can objectively and fairly evaluate the quality rate of map.The inspection mechanism model established by this method not only provides reference methods for map practi-tioners,but also for the country to establish relevant evaluation norms of maps.
