In view of the defects of the existing road obstacle detection methods, such as requirement for high registration accuracy, influence by imaging conditions , low-level automation and the need for professional operation, this paper proposes a road obstacle detection method based on reverse feature matching and accessibility evaluation method. On the basis of SIFT feature extraction algorithm, this method detects obstacles by acquiring the set of feature points that are not matched in the road buffer area of the disaster image, then obtains the distribution range and shape of obstacles by using a variety of sub-point region growing algorithms, and finally evaluates the road accessibility by overlapping analysis with road vector data. The experimental results show that this method can effectively extract the position information and shape information of obstacles.
