Embodiment 1

[0063] figure 1 It shows a schematic flowchart of the implementation of the image processing method in the billiards game provided by Embodiment 1 of the present invention. like figure 1 As shown, the image processing method in the billiards game may specifically include the following steps:

[0064] Step S101: Capture video information including the table top of the pool table and the billiard balls on the table through the photographing device.

[0065] Wherein, the photographing device may be a camera, and a camera generally refers to a device capable of collecting video or image sequences, and may be an industrial camera, a network camera, a surveillance camera, a camera equipped with a computer itself, and the like.

[0066] Step S102: Analyze the video information based on the constructed projection model including the shooting device and the position of the billiard ball to obtain the position information of the billiard ball; the shape of the billiard ball in the ima...

Embodiment 2

[0102] Please refer to Figure 7 , which shows a structural block diagram of an image processing device in a billiards game provided by Embodiment 2 of the present invention. The image processing device 70 in the billiards game includes: a collection module 71 and an analysis module 72 . Among them, the specific functions of each module are as follows:

[0103] The collection module 71 is used to collect video information including the table top of the billiard table and the billiard balls on the table through the shooting device;

[0104] The analysis module 72 is configured to analyze the video information based on the constructed projection model including the shooting device and the position of the billiard ball to obtain the position information of the billiard ball; the shape of the billiard ball in the image contained in the video information is an ellipse.

[0105] Optionally, the video information includes the distribution information of the elliptical area correspo...

Embodiment 3

[0122] Figure 8 It is a schematic diagram of a terminal device provided in Embodiment 3 of the present invention. like Figure 8 As shown, the terminal device 8 of this embodiment includes: a processor 80, a memory 81, and a computer program 82 stored in the memory 81 and operable on the processor 80, such as an image processing method program in a billiards game . When the processor 80 executes the computer program 82, it realizes the steps in the above embodiments of the image processing method in each billiards game, for example figure 1 Steps S101 to S102 are shown. Alternatively, when the processor 80 executes the computer program 82, the functions of the modules in the above-mentioned device embodiments are realized, for example Figure 8 The functions of modules 81 to 82 are shown.

[0123] Exemplarily, the computer program 82 can be divided into one or more modules / units, and the one or more modules / units are stored in the memory 81 and executed by the processor ...

Abstract

The invention is applicable to the field of visual recognition of machines and provides an image processing method and device for a billiards game and a terminal apparatus. The method is applicable toa system including a shooting device and comprises the steps of: collecting video information including a table top of a billiards table and billiards balls on the table top through the shooting device; analyzing the video information based on a built projection model including the shooting device and billiards ball positions to obtain position information of the billiards balls, wherein the billiards balls in images included in the video information are elliptical in shape. Billiards balls in images included in video information are elliptical in shape and position information of the billiards balls in the images in the video information is obtained based on the projection model, so that the accuracy of position information is improved. The method is simple to implement and has great practicability and usability.

Description

technical field [0001] The invention belongs to the technical field of machine vision recognition, and in particular relates to an image processing method and device in a billiards game. Background technique [0002] In recent years, machine vision has begun to be applied to electronic scoring in billiards games. The existing implementation method is as follows: the video of the billiards game is collected through the shooting device, and then the position information of the billiards on the billiard table is obtained through the established model, and then the follow-up operation is performed to realize electronic scoring. Therefore, obtaining the position information of billiard balls on the billiard table is a key step. However, in the existing models, the billiard ball is regarded as a circle, and then the billiard ball is positioned to obtain the position information of the billiard ball. Moreover, since the height of the shooting device from the table top of the bill...
