Patent Filed by Canon Kabushiki Kaisha Generates Teacher Data for Image Recognition

Strategic Insights -

Researchers at Canon Kabushiki Kaisha have developed a system for generating teacher data for image recognition, which includes acquiring image data by capturing an image of a workpiece, segmenting the image data into multiple first areas, marking whether predetermined information is included in each area, and generating teacher data. The system also includes a trained learning model that receives image data obtained by capturing an image of a workpiece by the image capturing apparatus, and inputs difference information indicating a difference between image data of a first workpiece and image data of a second workpiece to the trained learning model to make a determination on the second workpiece.

Key Takeaways:

  • The patent, filed by Canon Kabushiki Kaisha, discusses a teacher data generation method, a trained learning model, and a system for image recognition.
  • The system involves acquiring image data by capturing an image of a workpiece, segmenting the image data into multiple first areas, and marking whether predetermined information is included in each area.
  • The trained learning model is created by inputting difference information indicating a difference between image data of a first workpiece and image data of a second workpiece.
  • The system makes a determination on the second workpiece by inputting difference information indicating a difference between image data of a third workpiece and image data of a fourth workpiece to the trained learning model.
  • The system includes a sensor and a trigger generation circuit, which transmit an image capturing trigger signal to the image capturing apparatus upon detection of a workpiece within a predetermined range.
  • The system also includes a robot, which causes a workpiece determined to be defective based on the trained learning model to move.

Statistics:

  • The patent number is 12444034.
  • The patent was filed on April 5, 2022, and published online on October 14, 2025.
  • The system includes an image capturing apparatus, one or more processors, and one or more memories storing instructions and a trained learning model.
  • The system makes a determination on a workpiece based on the trained learning model and difference information indicating a difference between image data of multiple workpieces.
