Embodiment Construction
[0040] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] The present invention provides a positioning method and system for tightly coupled weakly supervised learning based on a ternary network. Based on global features and local features, a reordering algorithm is used to obtain positive samples of image q, and a weak supervision algorithm is used to obtain negative samples of image q. The positive samples and negative samples are used as the training set of the triplet network; in the learning strategy, the global features and the local features are better coupled from the selection of the training sample tuple and the definition of the loss function, and the global features and the local features are realized. The mutual promotion of each other can learn more effective information representation methods and richer feature details from the training set; at the same...
