In the field of image processing technology, we provide a smart billiards training system. [Solution] This smart billiards training system uses multi-sensor fusion technology, including depth cameras, laser radar, and high-speed cameras, to accurately construct a three-dimensional model of the billiard table and ball, creating a more realistic training environment. The path simulation module automatically calculates the optimal hitting angle and hitting strength, helping the player find the optimal attack path. The system measures the friction coefficient of the tablecloth in real time and performs trajectory correction based on different tablecloth materials to ensure the calculated cue ball speed matches the actual situation and prevent trajectory deviation. If the player's hitting angle or strength deviates from the optimal calculated value, the system automatically corrects and provides optimization advice. The system also monitors the player's stance, grip, and body balance.
