MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202647086768 A) filed by Koninklijke Philips N. V. on July 15, 2026, for Coordinate System Calibration Of An Optical Sensor System.
Inventors include Krueger, Sascha; and Sommer, Karsten.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: Disclosed herein is a method for calibrating a first coordinate system of a field of view of an optical sensor system (140). The calibrating comprises a registering of the first coordinate system with a second coordinate system of a medical imaging system (100) using a keypoint detection module (412). The keypoint detection module (412) is configured for detecting as output keypoint elements (122) of a patient table (120) of the medical imaging system (100) within optical sensor data (414) in response to receiving the optical sensor data (414). The method comprises determining three-dimensional coordinates values descriptive of positions of detected keypoint elements (122) within the first coordinate system and receiving three-dimensional coordinates values descriptive of the positions of the detected keypoint elements (122) within the second coordinate system. One or more transformation parameters (420) are determined for a transformation from the first coordinate system to the second coordinate system.
