A real-time visual target identification method with a scale coordination mechanism determines the size of a to-be-identified subject by target segmentation, and coordinates the scale of a to-be-identified region in real-time target tracking, thereby improving the identification precision. The method comprises the following steps: firstly, carrying out image segmentation on an acquired image according to a contrast ratio, and segmenting a to-be-identified main body from a background to determine the size of the to-be-identified main body; besides, in a common real-time visual target identification process, a target tracking algorithm calculates the position of a tracking target main body in each frame, and provides the position of the main body for the target identification algorithm to complete identification. When the ratio of the size of the main body after target segmentation to the size of the main body after target tracking is higher than a threshold value, a scale coordination mechanism is staretd, and
