摘　　要：地图注记是描述地图要素的文本,在嵌入式三维绘制中,三维注记有利于地图要素的表达和信息展示,但三维地图要素之间注记压盖问题会直接影响到三维的绘制效果。基于一种网格编码算法设计了三维地图要素注记可视化方法,解决地图注记信息的压盖问题。实验结果表明,该方法具有良好的注记效果,可以满足嵌入式三维系统实时性的要求。Map annotation is text to describe map elements.In embedded 3D drawing,3D annotation is conducive to the expression and information display of map elements,but the annotation overlay problem among 3D map elements will directly affect the 3D drawing effect.Based on a grid coding algorithm,the visualization method of 3D map ele-ments annotation is designed to solve the capping problem of map annotation information.The test results show that this method has good annotation effect and can meet the real-time requirement of embedded 3D system.
