Oblique photogrammetry is a new and high technology developed in recent years,which has been widely used in topographic mapping.The contour data collection of vegetation coverage area based on oblique model has the defects of weak automation and low efficiency.Point cloud data has its unique advantages in contour generation.For sparse vegetation,this paper studies a contour generation method for fine classification of point cloud based on oblique model transformation.Through practical engineering application and accuracy analysis,this meth-od has good practicability,and the results meet the specification requirements of large-scale topographic map.
