摘要
To solve the problem of automatic tube structure recognition, a recognition method for complex tube structures based on local shape feature was proposed. The recognition method first obtained the different tube structures' shape. Then the obtained shape was converted to a signal by shape descriptor. Batches of signal samples was collected and applied to train a BP neural network to classify the different tube structures. The training experiments showed that the recognition method had accuracy in 97%. In a certain application, multi-cameras were applied to recognize the tube structures and a voting method was also applied to increase the accuracy, which could be applied to reconstruct and measure multi-branch tubes automatically.
