Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] This embodiment discloses a method for identifying and tracking spherical objects in motion, please refer to figure 1 ,include:

[0039] Step S101, extracting sphere features

[0040] (1) Convert the RGB image containing the sphere into a grayscale image f1 and an HSV image f2 respectively. Calculate the Hough circle transform on the grayscale image f1 to find the circle c(a,b,r) in the image. c is a vector containing information about the detected circles, see figure 2 , the first element a in the vector is the abscissa of the circle, the second element b is the ordinate of the circle, and the third element r is the radius of the circle.

[0041] (2), count the color distribution within the range of circle c in f2, take the colors with the largest proportion as the main colors, and set the range of the main colors As texture features, whe...

Description

technical field [0001] The invention belongs to the field of recognizing and tracking spherical objects in motion, and in particular relates to a method and device for recognizing and tracking spherical objects in motion by using image analysis technology and filter prediction technology. Background technique [0002] Recognition and Tracking of Spherical Objects in Motion The main task is to recognize spherical objects in a given video and track the trajectories. [0003] The current existing method is to use the texture color information and background difference of the sphere in a single frame image to identify the moving sphere, and use algorithms such as mean shift to track it. Due to the existence of noise and occlusion, the recognition method is unstable only by relying on a single frame image to recognize the target, which is easy to cause misidentification of the target, and the tracking effect is poor in complex backgrounds and fast-moving spheres; especially if ...
