Abstract: A target tracking method and device are provided. The method includes: determining a vertical projection integral image and a horizontal projection integral image of a first region in a current frame of image captured; calculating a vertical projection curve and a horizontal projection curve of a target image in the current frame of image by utilizing the vertical projection integral image and the horizontal projection integral image of the first region; calculating a similarity between the target image in the current frame of image and the target image in a previous frame of image according to the vertical projection curve and the horizontal projection curve; and determining whether the target image in the current frame of image is a target image to be tracked according to the similarity.
