Embodiment Construction

[0068] A specific embodiment of the present invention-a high-speed moving target tracking system will be described in detail below in conjunction with the accompanying drawings.

[0069] One, such as figure 1 As shown, the method flow of the high-speed moving target tracking system has 1) image acquisition, 2) target designation, 3) binarization threshold window designation, 4) image binarization, 5) target tracking when the field of view is fixed, 6) target There are eight steps of position output, 7) field of view rotation processing and 8) target loss processing. Its working process is as follows:

[0070] The image acquisition function continuously acquires grayscale images with a certain period.

[0071] Before tracking starts: the first step is to specify the target to be tracked. Can be specified manually or automatically. A simple manual designation method is: manually point the camera at the target so that the midpoint of the field of view is on the target. The s...

Abstract

The invention relates to a high-speed target tracking method and relative circuit system, wherein the track process comprises that: hand-operated or automatically appointing target; using the area character of target as reference to set the area character threshold value window, using said window to make input image binary; then processing the image of each frame to track the target; when the target is lost, treating target as lost; when the target will release from camera, rotating the camera to the target, treating; outputting the target position of each frame. The invention has simple operation, high speed, and parallel treatment. And the invention also provides a hardware system.

Description

technical field [0001] The invention relates to the technical field of image information processing, in particular to a target tracking method and a circuit system thereof. Background technique [0002] Real-time tracking of moving objects is an important topic in the field of image information processing. Template matching and background subtraction are two common information processing methods for extracting and tracking moving objects. Template matching is a method of using the existing target feature data as a template to search for matching points in the image containing the target to find the target. This is a target retrieval and tracking method based on the morphological characteristics of the target. The template matching method has high sensitivity and reliability when applied to tracking, and has been widely used. However, due to the large amount of computation in the target retrieval and tracking information processing of the template matching method, the syst...
