Latest Patents

Takagi’s listed patents address image-based measurement and sports analysis.

- Image Processing Device, Image Processing Method and Image Processing System. This invention identifies two reference points and a physical characteristic point in a moving image. It determines the angle of the line connecting the reference points, calculates a conversion ratio between image length and real-world length, and uses that ratio to calculate real-space coordinates for the identified points.

- Information Processing Apparatus, Information Processing Method, and Storage Medium. This invention acquires video of a golfer’s swing, calculates a swing feature amount, and applies a conversion formula to estimate the behavior of the golf-club head.

Career Highlights

Takagi’s listed inventions connect image processing with practical measurement and sports-performance analysis. One patent describes converting positions in video into real-space coordinates, while the other uses swing-video features to estimate club-head behavior. Both reflect applications of information processing to analyzing movement.
