基于无人机倾斜摄影技术的农村宅基地地籍测量方法研究

Research on Cadastral Measurement Method of Rural Homestead Based on UAV Oblique Photography Technology

现有的地籍测量技术大多关注平面位置的测量,对高程信息的获取和处理较少,这可能导致存在较大的地籍间距差异,从而降低地籍测量的整体精度,为此,有必要开展基于无人机倾斜摄影技术的农村宅基地地籍测量方法研究。首先,设计和布设农村宅基地地籍测量的控制点,为后续的测量工作提供精确的空间参照。接着,运用无人机倾斜摄影技术,从多个角度获取宅基地的详细影像数据。最后,利用影像密集匹配技术,对获取的影像进行自动匹配和拼接,从而实现高精度、高效率的地籍测量。实验结果表明:该农村宅基地地籍测量方法以其高精度、和稳定性好的特点,为地籍管理提供了准确可靠的数据支持,具有重要的实际应用价值。

Most of the existing cadastral measurement technologies focus on the measurement of plane position,and the acquisition and processing of elevation information are less,which may lead to the existence of large cadastral spacing difference,thus reducing the overall accuracy of cadastral measurement.For this reason,it is necessary to carry out the research on the cadastral measurement method of rural homestead based on UAV oblique photography technology.Firstly,the control points of rural homestead cadastral measurement are designed and laid out to provide accurate spatial reference for subsequent measurement work.Then,the UAV oblique photography technology is used to obtain the detailed image data of the homestead from multiple angles.Finally,the image dense matching technology is used to automatically match and stitch the acquired images,so as to achieve high-precision and high-effi ciency cadastral measurement.The experimental results show that the rural homestead cadastral measurement method provides accurate and reliable data support for cadastral management with its high precision and good stability,and has important practical application value.
