    • The present invention is directed to a calibration apparatus and method for calibrating and verifying the accuracy of a golf ball launch monitor. The apparatus includes a support structure and a rotatable wheel that has embedded golf balls evenly dispersed at a known distance from the center of the wheel, and a field of view opening in a protective cover. A power device, typically an electric motor, rotates the wheel at a predetermined speed to establish a known speed and spin rate of the golf balls. Each golf ball surface includes contrasting markings. Camera(s) of the launch monitor are focused on the field-of-view wherein each camera is triggered such that two images of a ball are captured. The monitor has a computer to analyze data for speed and spin rate of the golf balls. A comparison of this data to the established known speed and spin rate of the calibration apparatus enables determination of the accuracy and repeatability of the monitor.
    • 本发明涉及一种用于校准和验证高尔夫球发射监测器的精度的校准装置和方法。 该装置包括支撑结构和可旋转轮,其具有从车轮中心以已知距离均匀分散的嵌入式高尔夫球,以及在保护盖中开口的视场。 功率器件(通常为电动机)以预定速度旋转车轮以建立高尔夫球的已知速度和旋转速率。 每个高尔夫球表面都包括对比标记。 发射监视器的摄像机集中在视场中,其中每个摄像机被触发,使得捕获两个球的图像。 显示器有一台计算机来分析高尔夫球的速度和旋转速度的数据。 该数据与已建立的校准装置的已知速度和旋转速率的比较使得能够确定监视器的准确度和重复性。
