Algorithm: An algorithm for extracting operation patterns of industrial robots Input: Hash sequence 0: Output: Hash sequence 3: Definition 1: Definition , is the image hash value calculated after image segmentation of a single frame industrial robot. Definition 2: Definition robot attitude vector and approximately equal, so that , where D(H1, H2) is Hamming distance between H1 and H2, and δ is the given similarity threshold. Steps: 1) Set Q suffix sequence of 2) Make any hash sequence , 3) st. 4) Let and 5) get the common prefix subsequence of Q1, Q2 6) for i in n: 7) if 8) Add to common prefix subsequence set H(Q) 9) end for 10) Q3 = Softmax(H(Q)) 11) Output Q3 |
