The invention discloses a target tracking and positioning method and device and a computer readable medium, and the method comprises the steps: determining a video image of a first frame in a video sequence as a template frame which comprises a to-be-tracked target and a position of the to-be-tracked target, determining a video image of any frame after the first frame in the video sequence as a search frame, inputting the search frame and the template frame into a template branch and a search branch in a twin network framework of a convolutional neural network model to perform feature extraction and convolution operation so as to obtain a response graph, processing the response graph by using a channel attention mechanism, and performing point multiplication on the response graph and the channel attention mechanism so as to obtain a first feature graph, processing the first feature map by using a space attention mechanism and is subjected to point multiplication with the first feature map to obtain a second f
