[0048] Below by example, further describe the method of the present invention in conjunction with accompanying drawing.
[0049] For a group of test image sequences A, use the method of the present invention to carry out image registration, the specific process is as follows:
[0050] 1. Use the ORB algorithm to perform fast feature extraction on each image in A, and obtain the feature points of each image;
[0051] 2. Introduce the K-D tree in the rough matching of feature points. Since the descriptor of each feature point is a 256-bit binary string, it can be used as 32-dimensional data, with 8 bits per dimension. It is applied to the K-D tree construction, and then found based on BBF search The points closest to this feature point are used as a pair of matching points;
[0052] 3. Apply ratio test and cross test to the obtained matching point pairs, eliminate the wrong matches, and keep the remaining ones as fine matching point pairs;
[0053] 4. Perform multi-layer RANAC...
