Abstract :
In this paper, canny Operator and Dominant Point Model was used to extract and express line elements of line-array imagery. Based on GC3 multi-image matching model of point element, a multi-image matching model for line element was proposed. Multi-image matching tasks of line elements could be solved indirectly through the proposed model. Experimental results proved that the model could obtain correct matching results but had a low and improvable successful rate.
