Research on Cadastral Measurement Method of Rural Homestead Based on UAV Oblique Photography Technology
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 meth-od 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 match-ing technology is used to automatically match and stitch the acquired images,so as to achieve high-precision and high-efficiency cadastral measurement.The experimental results show that the rural homestead cadastral measure-ment method provides accurate and reliable data support for cadastral management with its high precision and good stability,and has important practical application value.
