Homography matrix based trajectory planning method for robot uncalibrated visual servoing [PDF]
2023 IEEE International Conference on Real-time Computing and Robotics (RCAR), 2023 In view of the classical visual servoing trajectory planning method which only considers the camera trajectory, this paper proposes one homography matrix based trajectory planning method for robot uncalibrated visual servoing. Taking the robot-end-effector frame as one generic case, eigenvalue decomposition is utilized to calculate the infinite ...

A stereo matching algorithm based on SIFT feature and homography matrix
Optoelectronics Letters, 2015 Aiming at the low speed of traditional scale-invariant feature transform (SIFT) matching algorithm, an improved matching algorithm is proposed in this paper. Firstly, feature points are detected and the speed of feature points matching is improved by adding epipolar constraint; then according to the matching feature points, the homography matrix is ...

A Cost Function for the Uncertainty of Matching Point Distribution on Image Registration
ISPRS International Journal of Geo-Information, 2021 Computing the homography matrix using the known matching points is a key step in computer vision for image registration. In practice, the number, accuracy, and distribution of the known matching points can affect the uncertainty of the homography matrix.
