Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] The automatic seam tracking method based on deep neural network includes seam feature point detection network and seam feature point tracking network. The specific network implementation diagram is given by figure 1 give. The weld feature point detection network is mainly composed of a feature extraction module, an attention mechanism module, a priori frame generation module, and a recognition and positioning module. The feature extraction module uses the deep neural network to extract the features of the weld image. The attention mechanism module is to make the network put more attention resources near the laser stripes and weld feature points. The a priori frame generation module allows the network to transfer from global detection feature points to local detection, reducing the difficulty of extracting weld fea...
