航测技术在第三次全国国土调查地籍测绘中的应用

Application of Aerial Survey Technology in the Cadastral Mapping of the Third National Land Survey

为了提高第三次全国国土调查的准确性和智能化水平,在第三次全国国土调查地籍测绘中采用无人机和地测遥感采集方法,采集地籍测绘数据样本,进行地籍测绘图像信息融合。论文介绍了航测技术在地籍测绘中的应用。通过图像处理和边缘轮廓特征检测方法,实现对地籍测绘图像样本信息的特征分析和数据解算;通过空间遥感探测和图像特征提取,实现地籍测绘及国土调查。实验结果表明,采用该方法进行地籍测绘的精度较高,清晰度较好。

In order to improve the accuracy and intelligence level of cadastral surveying and mapping in the third national land survey,UAV and remote sensing collection methods are used to collect data samples and fuse image information.The paper introduces the application of aerial survey technology in cadastral surveying and mapping.Through image processing and edge contour feature detection methods,the feature analysis and data calculation of cadastral mapping image sample information are realized;through space remote sensing detection and image feature extraction,cadastral mapping and land survey are completed.The experiment results show that the cadastral mapping by this method has higher precision and better clarity.
