农村宅基地测量是确权登记发证工作的基础,文中在研究现有农村宅基地测量方法的基础上,探讨无人机倾斜摄影技术在农村宅基地测量方法,利用无人机搭载的倾斜相机获取序列影像,结合布设的控制点,通过特征提取、空三测量、多视影像密集匹配,然后构建不规则三角格网和纹理映射,进行三维重建和真正摄影像生成,最终在CASS软件平台下进行数字化成图。选取周口市淮阳县某村庄进行试验,结果表明,该方法不仅减少外业人力物力,而且精度完全满足技术规程要求,为农村宅基地测量提供一种新的方法。
Measurement of rural residential land was the basis of ownership registration certification work. On the basis of studying the existing measurement methods of the rural residential land, the measurement method of the UAV tilt photography in the rural residential land was discussed. Combining with the layout of the control points, through the feature extraction, the aerial triangulation, the multi - view image - dense matching, the irregular triangular grid and the texture mapping were built, and three -dimensional was rebuilt and the true photographic image was formed, finally, digital mapping was carried out in the CASS software platform. A village in Huaiyang County of Zboukou city was selected to carry out the experiment, the results showed that the method not only reduced the manpower and material resources, but also meet the requirements of the technical specification providing a new way for the measurement of the rural residential land.
