Introduction

In this article, we will delve into the fascinating world of the Pool AI project developed by Pacquis. This video reveals the complexities involved in creating an AI that can efficiently and accurately play pool. Pacquis shares insights into the different tasks that need to be solved to achieve this AI, highlighting the ball locating and Q locating challenges, the use of YOLO v5 model for object detection, the effort behind data collection, the significance of shot making range, the real-time aiming system, and the algorithms behind shot suggestions. We will also discuss the limitations of the current system and explore possible future improvements.

Ball Locating and Q Locating

The first major obstacle in the Pool AI project is the accurate identification of ball locations and the precise location of the cue ball (Q). This information is crucial for the system to function effectively. To tackle this challenge, Pacquis has trained a YOLO v5 model, which is an advanced object detection algorithm. YOLO stands for You Only Look Once, and it splits the image into numerous grids to detect objects. Pacquis has used around 20,000 images to train the model, which was a time-consuming and meticulous process. The object detection capabilities of the AI allow it to locate each ball accurately, empowering it to make informed decisions during gameplay.

YOLO v5 Model for Object Detection

YOLO v5 is a cutting-edge object detection algorithm that revolutionizes the way objects are identified in images. By analyzing grids and storing object information within them, YOLO v5 achieves exceptional speed and accuracy. However, the algorithm's efficiency is heavily dependent on the availability of a large and diverse dataset. Pacquis Mentioned the challenges of collecting and labeling the required images, emphasizing the tremendous effort required to ensure an extensive dataset. Through diligent data collection, Pacquis has optimized the YOLO v5 model for accurate object detection, enhancing the performance of the AI in pool gameplay.

Challenges in Collecting Data

Collecting data for the Pool AI project has been a formidable task. As Pacquis demonstrated in the video, labeling images alone took approximately 10 hours to complete. The dataset of 20,000 images significantly contributes to the AI's ability to accurately detect objects on the pool table. The time and effort invested in this phase of the project underscores the importance of quality data in training the AI model. The dedication to data collection is a testament to Pacquis' commitment to achieving accurate and reliable gameplay.

Importance of Shot Making Range

Pacquis highlights an essential aspect of pool gameplay often overlooked by many - the variation in shot making range across different pockets on the table. Not all pockets on the table have the same range for accepting shots. This means that certain shots may be feasible in one pocket but impossible in another. To address this, Pacquis has developed a polygon-based system that covers the shot making range for all pockets. By ensuring that shots Align with the appropriate polygon area, the AI ensures successful pocketing, enhancing its gameplay capabilities.

Real-Time Aiming System

The real-time aiming system adds another layer of complexity to the Pool AI project. To simulate accurate aiming, the AI must comprehend the table dynamics and calculate precise angles based on the player's cue movements. Pacquis demonstrates the system's functionality in the video, showing how it automatically detects the aimed angle and calculates the bouncing point. This advanced system incorporates extensive mathematical calculations to consider the ricochet of balls, allowing the AI to analyze multiple bouncing lines and determine the optimal angle of attack.

Accuracy Issues with Real-Time Aiming

While the real-time aiming system is an impressive feature of the Pool AI project, Pacquis acknowledges the current limitations in accuracy. The detection of the cue ball pose poses a challenge, causing the marker to bounce when the cue is moved. Pacquis explains that this issue arises from solely relying on object detection for cue tracking. To enhance accuracy, incorporating a physical marker on the cue, captured by the camera, could potentially provide more stable and consistent positioning. Despite this limitation, the current performance of the real-time aiming system is commendable.

Shot Suggestion Algorithm

The shot suggestion algorithm is a noteworthy feature of the Pool AI project. By analyzing all the balls on the table, the AI can determine the optimal shot without involving bank shots, kick shots, or caroms. Pacquis has implemented a reward system that factors in the angle of the shot, the distance between balls, and the proximity to pockets. These factors collectively contribute to a difficulty score, which guides the AI's decision on the best shot to take. The shot suggestion algorithm currently covers both solid and stripe shots, demonstrating its potential to enhance gameplay strategies.

Limitations of the Shot Suggestion Algorithm

While the shot suggestion algorithm shows promise, Pacquis highlights some limitations. The algorithm currently does not differentiate between the player's turn to shoot solid balls or stripe balls. However, this is an aspect that Pacquis intends to address in future iterations of the AI system. Additionally, the algorithm faces challenges in accurately detecting pocketed balls. The stability of the detector and occasional obstructions caused by the player can result in inaccurate ball count. These limitations Present opportunities for improvement and refinement in future versions of the AI.

Future Improvements

Looking ahead, Pacquis envisions various improvements to the Pool AI project. First on the list is the incorporation of bank shots, caroms, and kick shots, which will elevate the AI's capabilities and make gameplay more challenging. Additionally, Pacquis plans to incorporate position play into the AI system, enabling it to calculate shots ahead and strategically plan gameplay. These enhancements will undoubtedly take the Pool AI to new heights, elevating its gameplay to match the skills of professional players.
