Abstract: After the traditional evaluation model of contours’ quality is analyzed,a novel evaluation model is proposed.In which,the contours’ accuracy is evaluated based on entropy and the smoothness is evaluated based on shape index.And then the detail procedure is described.Finally,the feasibility of the evaluation method is varified by experiments.

Key words: Airborne Light Detection And Ranging(LiDAR), contours, entropy, smoothness

摘要: 分析了传统等高线质量评价相关模型,提出了基于信息量的等高线精度评价方法和基于形状指数的等高线光滑度评价方法,并给出了具体的量化计算过程;最后通过实验验证了该评价方法的可行性。
