Abstract

The invention relates to the field of image tracking, in particular to an image tracking and positioning method and a system based on machine vision. The gray-scale image of the previous frame and thegray-scale image of the current frame taken by the panoramic camera are subjected to frame-to-frame difference to obtain a frame-to-frame difference image; morphologically etching is performed on theframe difference image with the first kernel to obtain the etched image and morphologically dilating is performed on the etched image with the second kernel to obtain the frame difference image; allthe outer contours in the detected frame difference image take the maximum contour as the detected moving object; the coordinate transfer matrix is used to transform the outer rectangular center to obtain the moving position of the camera; a zoom transfer matrix is used to transform the center of the outer rectangle, and the zoom coefficient is obtained; the first step is repeated by replacing thegray image of the previous frame with the gray image of the current frame. The method and the system of the invention can realize low computational complexity and high processing efficiency of the image tracking algorithm, and also improve the expandability of the product.

Description

technical field [0001] The invention relates to the field of image tracking, in particular to an image tracking and positioning method and system based on machine vision. Background technique [0002] Image tracking technology refers to positioning the object captured by the camera in a certain way (such as machine vision, infrared, ultrasonic, etc.), and directing the camera to track the object so that the object is always kept within the camera's field of view. Technology. Image tracking systems are widely used in various industries such as education, conferences, medical care, court trials, and security monitoring. Among them, the fully automatic tracking shooting solution applied to education and conferences has led the technical trend of fully automatic tracking shooting at home and abroad, and laid a solid technical foundation for the fully automatic shooting of high-quality courses and video conferences. [0003] Most of the existing image tracking technologies use ...
