	1	3维面状要素注记的自动配置研究显示文摘随着3维地图的发展,2维地图中的一些注记自动配置规则和方法在3维环境下显得并不适用。在分析3维注记视觉变量及其影响因素的基础上,对3维地形图中面状要素的注记配置规则进行了研究,提出一种基于约束性Delaunay三角网提取面状要素注记定位线、并结合3维地形图中面状要素的符号特征获取注记定位点的3维面状要素注记自动配置方法,在基于ArcEngine的3维地形图自动绘制系统中得到了成功应用。	杨乃郭庆胜杨族桥	2009	测绘科学技术学报2009，26，6：	2
	2	A code-based approach for labeling in complex irregular regions显示文摘Labeling information in a complex irregular region is a useful procedure occurring frequently in sheet metal and the furniture industry which will be beneficial in parts management.A fast code-based labeler(FCBL) is proposed to accomplish this objective in this paper.The region is first discretized,and then encoded by the Freeman encoding technique for providing the 2D regional information by 1D codes with redundancies omitted.We enhance the encoding scheme to make it more suitable for our complex problem.Based on the codes,searching algorithms are designed and can be extended with customized constraints.In addition,by introducing a smart optimal direction estimation,the labeling speed and accuracy of FCBL are significantly improved.Experiments with a large range of real data gained from industrial factories demonstrate the stability and millisecond-level speed of FCBL.The proposed method has been integrated into a shipbuilding CAD system,and plays a very important role in ship parts labeling process.
