[0030] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] Such as figure 1 As shown, the object recognition method based on contour features of the present invention is used to identify objects in the image to be detected, and if there are multiple objects in the image to be detected, the objects in the image to be detected are recognized one by one. The method comprises the following steps S1-S2: S1, establishing a feature library of object template contours; S2, performing target recognition on the image to be detected.
[0032] Wherein step S1 includes the following steps S11-S14:
[0033] S11, extracting the complete outline of the object template, mainly under the static background, using the background difference method to extract the complete outline of the object template, the result of the outline is expressed as S={P i ;i=1...N}, where S represents the outline of the ...
