Embodiment Construction
[0051] The method of the present invention is as Figure 8 It includes five stages in total: adaptive threshold feature point detection, evenly distributed feature point acquisition, BRISK feature extraction, discriminable embedded random fern fast matching and post-processing.
[0052] Convention: I refers to the image to be detected; Refers to the SURF feature points selected by the adaptive threshold; Refers to the threshold that controls the minimum number of feature points in an image block; Refers to the feature points processed by the uniform distribution algorithm; Refers to the abscissa of the feature point; Refers to the ordinate of the feature point; Refers to the number of uniformly distributed feature points; Refers to the matrix used to store all BRISK feature information; Indicates the first of the data point features; refers to the number of binary decisions; fern one of the boxes; for class; Refers to the gray value of the real-time...
