  • Publication number: 20250077818
    Abstract: The embodiment of the disclosure provides a method for training a pattern enhancing model and an electronic device. The method includes: reading a first pattern with a defect via a pattern reader, and determining whether the pattern reader reads successfully; if a reading is successful, performing a pattern reconstruction operation based on pattern information of the read first pattern to obtain a second pattern; training the pattern enhancing model based on the first pattern and the second pattern as a training data set.

  • Publication number: 20240009849
    Abstract: A hand-eye calibration method and a hand-eye calibration device for a robot arm are provided. The method includes following steps. A first mapping relationship between a base of the robot arm and a terminal of the robot arm and a second mapping relationship between a camera and a target object are obtained. Based on a scale, a third mapping relationship between the terminal of the robot arm and a tool set mounted on the terminal and a fourth mapping relationship between the camera and the base in each dimension are updated to minimize an error between a position of the target object in an image captured by the camera and a position of the tool set. In response to the error being convergent and the scale being less than or equal to a scale threshold, the third mapping relationship and the fourth mapping relationship calibrated by the scale are output.
