"Golfboy" is a golf practice app for amateur golfers, developed to make golf practice easy and fun for everyone by utilizing computer vision technology and smartphone cameras.

For the low price of $10/month, Golfboy offers a variety of functions that golfers can use to practice, including

  1. Shot analysis (measures shot distance, ball speed, launch angle, and club speed)
  2. Putting analysis
  3. Automatic swing form analysis and recorder
  4. Round simulator



GolfboyLIVE is a ball tracking system built for broadcasting uses. The system automatically detects the ball on the green from the live input image, and renders the CG trajectory over the image.

The various features in the system aims to output maximum effects with minimum operation cost which is crucial for broadcasting production scenes.

  1. No special camera or sensor required. The green camera for normal broadcasting is the only necessary input.
  2. Switching the input source enables one GolboyLIVE unit to be used for multiple input images.
  3. Compatible formats are: 1080i59.94 / 1080p59.94 / 1080i50 / 1080p50.
  4. Input sound source is also directly embedded to the ouput.
  5. Only 6 field delay (3 frames)
  6. Remote control feature via browsers.
  7. Required hardware is only Macbook(M1,M2) and Blackmagick Ultrastudio.



Baseboy is a image processing based real-time pitching/batting tracking technology. Each of the 2 fixed cameras placed in the stadium detects the ball coordinate inside the camera image, and the system then restores this into a 3 dimensional trajectory. Compared to conventional speed guns or expensive radar systems, Baseboy can provide high accurate and low cost data. Baseboy is now used in live broadcasting, analysis inside pro and amateur baseball teams, and also an alternative to conventional speed guns.

In order to realize 3 dimensional tracking, the shutter timing must be synchronized among the 2 cameras. Baseboy has its most advantage where it does not require this synchronization, moreover, even the framerate among the 2 cameras do not need to match. Baseboy's pitching and batting tracking system is realized by such patented technologies (Patent No.6697150, 6579727, 6412998).

FigureSkating: "ice:stats"

ice:stats is an image processing technology developed to measure the performance for figure skate broadcasting. Stats such as "height", "distance", and "landing speed" is measured in semi-real-time for jump elements using the 4K camera placed in the arena. The measured data is shown in the arena vision and also on air during the Kiss and Cry after the performance. Spectators and viewers were only able to imagine each skaters' jump features, but with ice:stats, it is now possible to understand the condition of their jumps in a more objective way.

ice:stats also provides a feature to track the skater's performance and render its trajectory as a replay. This enables to visualize how much the skater has covered the entire rink during the performance.

Recent Usages

ISU Grand Prix Final / Four Continents Figure Skating Championships / World Figure Skating Championships / All Japan Figure Skating Championships


SmartArena Solution

By placing multiple fixed cameras inside the arena, this tracking system can be used to collect various data during training and competitions. The system collects not only ball and player positions, but it can also detect play events such as serves, spikes, along with its velocity and height. The data is automatically tagged so that team analysts and coaches can give quick feedbacks to the players. The camera image is recorded along with the tag information, so it is easy to jump to the desired play in the video.

Hardwares used: Mac mini, Mac Studio
