摘　　要：对机载激光雷达测量技术、ENVI Li DAR软件、建筑物提取流程进行了介绍,以ISPRS第三委员会提供的机载激光雷达点云数据为基础,基于ENVI Li DAR 5.1对实验区的建筑物进行了提取,并通过Arc GIS结合同地区影像对其质量进行评价,实验流程及结果有一定的参考意义。Technology of Airborne Li DAR（ Light Detection And Ranging）,the ENVI Li DAR and the process of building extraction are introduced briefly in this paper. Then,based on the International Society for Photogrammetry and Remote Sensing（ ISPRS） commission Ⅲ and ENVI Li DAR 5. 1,the buildings in testing area were extracted. The evaluation results of quality was learned by overlaying the buildings onto the image in same place through Arc GIS,and the process and results thereof have certain reference significance.
