Implementation and accuracy analysis of oblique photogrammetry in the"real estate integration"
In the"integration of housing and land"rural homestead and collective construction land confirmation registration project in Hetang Town,Pengjiang District,Jiangmen City,Guangdong Province,due to unfavorable factors such as dense housing,narrow alleys,lush vegetation,abundant rainfall,and poor GNSS signal,oblique photogrammetry technology and ContextCapture automatic modeling system were adopted to obtain 3D image results of the survey area.Using Tsinghua Shanwei EPS software for naked-eye stereo mapping,combined with field surveying and a small amount of supplementary measurement using total stations,the final DLG data was obtained.Field sampling was conducted for data detection,and a detection template with the same precision was used to automatically summarize the mean error and precision analysis of the detection points,verifying the geometric accuracy of the graphics.The results showed that this operation mode could meet the requirements of the real estate integration measurement project,with safe and efficient operation,low cost,reduced field work intensity,and certain application and promotion value.
