Summary

This study analyzed the quality of point cloud data generated based on LiDAR and CV analysis in terms of point density, absolute accuracy, and relative quality. LiDAR-based data showed higher vertical position accuracy than CV analysis-based data, and image spatial resolution and overlap significantly affected absolute accuracy in CV analysis. Furthermore, CV analysis through data fusion was found to be effective in improving quality.
