Seiko Epson Corporation Files Patent Application for Advanced Calculation and Projection Methods

Strategic Insights -

Seiko Epson Corporation has filed a patent application for an advanced calculation and projection method that uses convolutional neural networks (CNNs) to enhance image recognition and projection accuracy. The method, disclosed by inventor Takumi Aragaki, extracts feature points from material and object images, and derives a correspondence relationship between the points using a third CNN. This approach aims to improve the accuracy of image recognition and projection compared to existing techniques.

Key Takeaways:

  • The patent application describes a calculation method that includes extracting first and second feature points by performing convolution operations on material and object images, respectively.
  • The method derives a correspondence relationship between the feature points using a third CNN, and uses this relationship to perform geometric correction and project an image.
  • The control device executes the calculation method, extracting feature points, deriving the correspondence relationship, and performing geometric correction.
  • The patent application claims a calculation method, a projection method, and a control device, with specific embodiments describing the operation of the third CNN and the decrease of channel numbers in the first and second CNNs.
  • The invention aims to improve the accuracy of image recognition and projection compared to existing techniques.
  • The patent application is filed by Seiko Epson Corporation and assigned to the company.

Statistics:

  • The patent application was filed on March 26, 2025, and posted online on October 2, 2025.
  • The method includes extracting feature points from material and object images, with a third CNN deriving the correspondence relationship between the points.
  • The control device executes the calculation method, with specific embodiments describing the operation of the third CNN and the decrease of channel numbers in the first and second CNNs.
  • The invention aims to improve the accuracy of image recognition and projection, with potential applications in various fields.
