OESM辅助的高分辨率航空正射影像拼接线自动检测算法
Automatic Seamline Detection Algorithm for High Resolution Aerial Orthoimages with the Auxiliary Orthoimage Elevation Synchronization Model
摘要
Abstract
In view of the problem of the conventional seamline detection algorithm,that the seamline prone to pass through buildings will destroy the integrity of the ground feature while mosaicking urban region image,an algorithm of automatic seamline detection with auxiliary OESM is proposed,which exactly extracts ground objects by normalizing OESM firstly,and then an improved greedy algorithm is adopted to quickly detect a seamline in non-ground object areas.The experimental research of urban images in which building distribution is dense shows that the proposed algorithm is an ideal seamline detection algorithm.关键词
