Remote multi-target efficient detection and identification method

The invention discloses a remote multi-target efficient detection and identification method. The method comprises the following steps that S1, a terminal processes a video stream into a picture set through a current limiting algorithm; S2, original pictures of the picture set are normalized into sample images with fixed sizes; S3, with pixel points of the sample images as nodes, the state of an undirected graph is depicted by using an adjacent matrix of all the nodes; S4, an s latitude feature vector of each node is obtained; S5, a complete vectorized tag dictionary is pre-constructed, and predicted values of tags are obtained from the output feature matrix through the dictionary; S6, the terminal carries out threshold screening on the predicted values of the tags; S7, a server generates a corresponding hash code according to a tag result, and enters different target recognition model channels through the hash code; and S8, the server recognizes all known targets in advance and then stores the recognized targ
