Embodiment Construction

[0019] A visual positioning and broadcasting blind basketball court system based on multi-sensor information fusion, the system is mainly composed of the following parts:

[0020] Liftable basketball hoop driven by 2 motor screw rods; Camera equipment fixed on the ceiling; STM32 microcontroller controller; A wireless headset with a built-in orientation compass.

[0021] Two motor screws are placed on the basketball hoops on both sides. Blind basketball players wearing jerseys of different colors and wireless earphones with built-in positioning compass are located in the court area. The court area is divided into 12 monitoring areas; each earphone has a wireless The receiving module; wherein the camera is fixedly placed on the ceiling above the monitored area, and the direction is perpendicular to the monitored area.

[0022] The height of the basketball hoop is adjusted by the motor screw, and the color of the jersey is collected by the camera. The STM32 microcontrolle...

Abstract

The invention discloses a visual positioning broadcast basketball court system for the blind on the basis of multi-sensor information fusion. The system is mainly composed of a lifting type basketballhoop driven by two motor screw rods, a camera device fixed to a ceiling, an STM32 single-chip microcomputer controller, and a wireless earphone module internally provided with a compass. The system is accurate in positioning, high in intelligence degree, low in cost, capable of improving efficiency, and high in anti-interference capability.

Description

technical field [0001] The invention relates to a visual positioning and broadcasting blind basketball court system based on multi-sensor information fusion. Aiming at the actual situation of blind basketball, it is used for real-time personnel and item positioning monitoring and voice broadcasting through cameras in blind basketball, belonging to sensing and detection technology field. Background technique [0002] Blind people have many inconveniences in basketball due to visual problems, and college students in the United States have designed a basketball guidance system. They installed a sound generator behind the backboard, which can make rhythmic sounds to guide blind players to dribble and shoot. A smaller device installed in the basketball also emits a constant sound, allowing players to track the ball as it passes around the court or rolls across the boundary. The system also helps visually impaired children develop basic motor coordination. (Tian He. Basketball ...
