摘要:
为减少绘制电子地图时POI标签对道路的遮挡,提出一种检测POI标签与地图背景中道路是否产生重叠压盖并调整标签位置的方法。采用划分网格数据的方法减少检测计算量,对可能压盖路段进行过滤,提取可能与POI产生压盖的路段,再采用建立局部坐标系判断绘制元素斜率关系的方法,检测该POI标签是否与道路产生重叠压盖,进而做出调整。应用实例表明,该方法能以较高的效率增强地图显示效果,提升用户体验。更多还原
Abstract:
In order to reduce the coverage of POI tag on the road in drawing a digital map, a method is proposed to detect if the road will overlap the gland in POI tag map and adjust the tag position. The method of dividing the network data is implemented to reduce the detecting calculation cost, and the likely covering road unit is filtered to refine the road that is likely to create coverage with POI. A local coordinate system to determine the gradient relationship of the drawing elements is applied to detect if the POI tag covers the road and then adjustment is made accordingly. It is shown that the method efficiently increased the displaying effort of the digital map and improved user experience.
