  • Patent number: 12175556
    Abstract: A method, instructions for which are executed from a computer-readable medium, calibrates a robotic camera system having a digital camera connected to an end-effector of a serial robot. The end-effector and camera move within a robot motion coordinate frame (“robot frame”). The method includes acquiring, using the camera, a reference image of a target object on an image plane having an optical coordinate frame, and receiving input signals, including a depth measurement and joint position signals. Separate roll and pitch offsets are determined of a target point within the reference image with respect to the robot frame while moving the robot. Offsets are also determined with respect to x, y, and z axes of the robot frame while moving the robot through another motion sequence. The offsets are stored in a transformation matrix, which is used to control the robot during subsequent operation of the camera system.

  • Patent number: 12171495
    Abstract: A system and method quantify light exposure of a patient retina during an ophthalmic procedure. A light source illuminates the patient retina with directed light during the procedure to produce an illuminated retina surface. A camera collects image data of the illuminated retina surface. An electronic control unit (ECU) in communication with the camera and an indicator device receives the image data, calculates a cumulative energy spectral density of the directed light falling incident upon the retina, and executes a control action indicative of possible light toxicity in response to the cumulative energy spectral density exceeding a light toxicity threshold, including activating the indicator device. The illuminated retina surface may be divided into virtual zones, with the ECU mapping the cumulative energy spectral density to the illuminated retina surface. Each of the optional zones has a corresponding cumulative energy spectral density.
