Chengdu Jincheng College has applied for a patent titled “A Robot Vision-Guided Grasping Control Method and System”, which significantly reduces reliance on camera calibration and 3D reconstruction. The patent was filed on January 2026 and is published under the number CN121995830A.
The patent summary indicates that this application pertains to the field of artificial intelligence technology. It reveals a method and system for robot vision-guided grasping control, which includes the following steps: executing global coarse positioning; increasing the frame rate and switching to a high-frequency visual servo mode once the predefined distance threshold is reached; extracting the geometric vectors of feature points and calculating pixel residuals; introducing Kalman filtering to smooth the residuals, with the observation noise covariance matrix dynamically adjusted based on the real-time image signal-to-noise ratio; utilizing the image Jacobian matrix to map the smoothed residuals to six degrees of freedom velocity compensation; and finally, synthesizing the compensation with the original motion command vector, which is then weighted and normalized before driving the joint actuators until the residuals converge.
This system encompasses visual acquisition, feature extraction, residual calculation, a visual servo controller, and a motion execution module. Through this approach, high precision and robust dynamic grasping are achieved, which notably decreases the dependence on camera calibration and 3D reconstruction.
