STEMMER IMAGING not only supplies many of the cameras used by Quintic, but has also worked closely with them to ensure successful integration of the cameras with the software. The system utilises a high-speed camera (360 – 1080 frames per second) in combination with a custom-designed LED bar light to track the putter and golf ball throughout the impact zone of either a right handed or left handed player.

Quintic is a specialist in Premier Sports Video Analysis Software, Sports Biomechanics & Performance Analysis Consultancy. STEMMER IMAGING has worked closely with Quintic Consultancy Ltd during the development of the Quintic Ball Roll system for analysing putting performance in golf. This allows for the fact that not only is the puck is smaller and faster than a football and not spherical, but it also rotates in the air during flight.īall tracking is also an important part of sports coaching as well in officiating and is often used in conjunction with biomechanics. There is also an ice hockey version of RoboKeeper, which utilises cameras with a higher resolution and a faster frame rate. These lenses have a focal length of 3.5 mm, so the angle is wide enough to guarantee recognition of the ball from the penalty spot to the goal. The system allows RoboKeeper to move to that position within 300 ms – making it rather difficult to score! To compensate for variations in lighting conditions for outside events, the camera systems are equipped with lenses with an automatic iris controller and a motorised iris controlled by the video signal. Within this time, the probable trajectory of the ball and the position where it will reach the plane of the goal must be extrapolated and the complete movement of the goalkeeper, including all motor acceleration and braking procedures, must be completed in order to prevent a goal. This position represents the maximum distance RoboKeeper has to move. If the ball were kicked at around 62 mph in a flat trajectory, it would take 360 ms to reach the bottom left or right corner of the goal. As soon as the system detects that the ball has crossed the goal line, it instantaneously sends a signal to the officials’ watch.

Control software combines the information from all cameras and is able to track the ball within the goal area. The images are processed to find the ball within the image and also identify areas, which are definitely not the ball. Combined with on screen graphics, the systems are used in tennis to review line decisions and in cricket to check leg before wicket (LBW) decisions as part of a player review system.įor goal line technology, the system is continuously monitoring images from 7 cameras focused on each goal. These are triangulated using sophisticated software to give an accurate 3D trajectory of the ball in real time. Multiple cameras located around the stadia produce individual images of the ball in motion.

These types of system have been approved by many of the leading authorities in world sport and are very familiar to TV viewers, having become an essential part of sports broadcasting. In addition, the ball's angular velocity vector can be displayed during the live capture, which is able to demonstrate spin-bowling performance in the laboratory.STEMMER IMAGING has been involved in ball tracking technology for many years, having worked closely with Hawk-Eye Innovations to deliver imaging technology for the decision review systems used internationally in sports such as cricket and tennis and for goal line technology in football. In particular, it was found that wrist-spin bowlers could potentially swerve the ball either towards the left or right of the batsman. The results show that spin bowlers can produce various combinations of spin rate and angular velocity vector orientations to implement substantially different methods of utilising both swerve and turn off the pitch to deceive the batsman. Thirty-four district-level spin bowlers, including both finger-spinners and wrist-spinners, were recruited to bowl 20 standard deliveries, and 5 deliveries of any variation in their repertoire. Data were further processed using 3D vector kinematics to calculate the ball's linear speed, spin rate and direction of the angular velocity vector.

A three-dimensional (3D) Cortex motion analysis system was used to track three markers strategically placed on the ball spinning in flight.

The purpose of this study was to analyse the performance outcomes of spin bowlers by using a motion analysis procedure to measure the linear and angular kinematics of a spinning ball.
