The transferring strategy of conjugate points in image matching has a great effect on the accumulation of random error.Firstly,each image pair was related by the endlap and sidelap direction according to different transferring strategies.Initial alignment and pyramid based precise image matching were performed after feature points were extracted.Finally,bundle adjustment was performed to evaluate the precision of different conjugate points transferring strategies.Two different conjugate points transferring strategies for both endlap and sidelap were performed and evaluated with experimental data sets.It showed that the transferring strategy from a certain feature point to both directions of endlap and sidelap was superior to that of the traditional strategy.
