Three dimensional golf swing analyzer

摘要

An apparatus, system and method for golf swing analysis is described using a first microprocessor, a three-axis accelerometer that transmits linear acceleration data to the first microprocessor, a three-axis gyroscope that transmits angular velocity data to the first microprocessor, data processing, a radio transmitter for transmitting processed data, and a housing for holding the components, which attaches to a golf club. A camera with image recognition software and an ultrasonic and RF navigation system are used for error correction. A camera on the portable device may be used to capture video, which is trimmed to correspond with the animation, and the video may be placed side by side with the animation for visual analysis. Further error correction occurs using image sensors to determine moving object speeds and coordinates.
