Latest Patents

Lei Fu holds a patent for a "Monocular vision-based method for measuring displacement and trajectory of planar motion." This method involves collecting a sequence image of a high-contrast feature mark fixed on a moving plane using a camera. The technique employs a sub-pixel edge detection method to extract the sub-pixel coordinates of the feature edge during linear motion in both the X and Y directions. These coordinates are then converted into corresponding world coordinates. By applying a least squares principle, the world coordinates of the feature edge are fitted to obtain a straight line, allowing for the decoupling measurement of displacement in both directions. The trajectory of planar motion is subsequently determined through these measurements.
