First, the table gets detected by using a mask for the table color and the difference of color of the dark areas beside the cushions. Second, the balls get detected by a fine-tuned YOLOX model. Third, detect the direction of the cue stick and calculate the path of the ball and whether it will go […]
Task Solution Approach: Using HSV Color Spacing to Extract Color Mask. Detecting the Cue, Cue Ball and Color Balls using Contours. Then predicting the path of the Color Balls using Mathematical Analysis and Setting Thresholds. Handling the situation if the Ball Touches the Wall, bounces back and goes into the Pocket or Not. Setting the […]
The steps taken are described: 1) Find the table using HSV space; 2) Using contours, the pocket holes are found; 3) Cue ball and stick is found by contours too; 4) The target ball is found using HoughCircles; 5) A line is predicted from the stick along the cue ball to simulate the path of […]
I created a program that predicts the path of pool balls by using OpenCV and Numpy for color and shape detection. Different HSV filters are defined for each object, and coordinates of each object are used to calculate the likely ball path based on linear algebra. To account for the uncertainty in the cue’s exact […]
First I had to learn about the physics of pools. Angles are only perfect under specific conditions of hitting force, speed, cue or ball hit position, etc. As this video is made by a human, not all scenarios are perfect, and there is where we have magic. I used a contour approach, finding contours of […]
The outcome of a shot in the game of pool based on a video of the game. The code is loads a video file and processes each frame to detect the position of the pool balls and the edges of the pool table. It then predicts the path of the cue ball and determines whether […]
This is my pool shot detection program that predicts the path and outcome (in or out) of 10 pool shots provided by CVZone. I used two libraries: OpenCV and NumPy. My process started with detecting the cue ball and colored balls using several different Hue/Saturation/Value (HSV) filters and contour detection. Only contours with a certain […]
Firstly, I would like to thank CVzone and Nvidia for hosting this competition. I have implemented Pool Shot Predictor project that predicts the path and outcome of 10 pool shots provided in the video. In the first step, we import all the required libraries, including numpy, opencv-python, math, pillow library. In the next step, we […]
The main method used is color and shape detection to discern the objects on the pool table. To each object, the program defines a different HSV filter. With the coordinates of each object, it calculates the likely path of the ball based on linear algebra. As the program can't estimate the exact location of the […]
This predictor is built completely using OpenCV and Numpy. It works by first finding the HSV-masks for the playing field and the pool cue. We then find the playing field and define the edges of the field using the best fitting square given by the edges of the playing field by using min/max of found […]
