Target tracking method and device

Abstract

The present application provides a target tracking method and device. The present invention obtains the feature map corresponding to the first frame image by inputting the first frame image into the convolutional neural network; obtains the feature template of at least one target object in the processed second frame image, and the second frame image is higher than the first frame image The image sequence is first; then the feature map is matched with the feature template of at least one target object to obtain at least one target object matched in the feature map; thus according to the matched at least one target object in the feature map corresponding to the first frame image The position information determines the target position of the at least one matched target object in the first frame image, so as to achieve the purpose of tracking the target object. The present invention firstly inputs the entire frame of image into the convolutional neural network to obtain the feature map of the entire image in a short time, and then matches the feature map with the feature template of the target object in the previous frame image to obtain the position of the target object to be tracked, and the tracking speed is fast , which improves the tracking experience.

Description

technical field [0001] The present application relates to the field of target detection and tracking, and in particular to a target tracking method and device. Background technique [0002] Target tracking is mainly used in scenarios such as video surveillance, human-computer interaction, virtual reality, and drone reconnaissance. Usually when tracking a single target object, it is necessary to adjust the size of the image according to the requirements of the convolutional neural network, intercept the image of the target object area in the image for convolution to obtain the corresponding feature map (time-consuming), and then The feature map is matched with the target template to identify whether the target object needs to be tracked, so as to realize the tracking of the target object in the video image. The process of extracting the feature map of the target object area in the original image takes a long time, the process is cumbersome, and the experience of real-time tr...
