MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611009512 A) filed by Swami Vivekananda Subharti University, Meerut, Uttar Pradesh, on Jan. 30, for 'a method and system for real-time structured-light-based seam geometry extraction and adaptive trajectory control in arc welding robots.'
Inventor(s) include Rahul Kumar; Chitranjan Kumar; and Sandeep Kumar.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system and method for intelligent robotic arc welding through real-time seam geometry extraction and adaptive trajectory control. The invention integrates a structured-light vision sensor with an arc welding robot, wherein a structured-light pattern is projected onto a welding surface and images of the deformed pattern are captured during operation. The captured images are processed in real time to extract weld seam geometry, including seam position and orientation. Based on the extracted seam geometry, the system automatically generates or corrects the welding trajectory of the robot during operation, thereby enabling intelligent path instruction without manual reprogramming or repeated teaching. A coarse-to-fine seam extraction strategy is employed to reduce computational load while maintaining high measurement accuracy under varying seam geometries and surface conditions."
