Badminton swing detection machine is a special equipment used to detect the stability of badminton and ball speed. The equipment makes use of the wind tunnel suspension effect, so that the badminton suspended in the wind tunnel, through the camera imaging, and then dynamic detection and analysis of the image, real-time detection of the badminton swing state; By measuring the suspension height of the badminton in the wind tunnel, the corresponding flying speed of the badminton was calculated（74-78）, and the results were classified and output by different stations. The machine combines machine vision, servo drive and photoelectric detection technology in one, stable and efficient operation; Effectively reduce the cost of production end, improve production efficiency.
