Research and application of precision detection technology for digital orthophoto map
LIU De-wei
Abstract：Accuracy detection of digital orthophoto map is an important work in DOM production.Traditional manual work is time-consuming and labor-intensive,which seriously impacts the production progress of the project.Based on the analysis and research of 1∶ 1 000 DOM production project precision detection,this paper constructs a DOM precision detection system based on AutoLISP,which has the integration of DOM precision detection data collection,detected data association with detected data,precision calculation and statistics,and report output.The study indicates that it only takes 49.0 s to complete the precision inspection of about 6 650 pairs(groups),and the standard specification of precision inspection report is verified by manual inspection,which is accurate and reliable.The DOM precision detection system can greatly reduce the work intensity of manual inspection and provide a scientific and effective method for the project acceptance.
