  • Publication number: 20210110575
    Abstract: Systems and methods for automatic camera calibration without using a robotic actuator or similar hardware. An electronic display screen projects an image of a simulated three-dimensional calibration pattern, such as a checkerboard, oriented in a particular pose. The camera captures an image of the calibration pattern that is displayed on the screen, and this image together with the transform of the simulated three-dimensional calibration pattern are used to calibrate the camera. Multiple different pictures of different poses are employed to determine the optimal set of poses that produces the lowest reprojection error. To aid in selecting different poses, i.e., spatial positions and orientations of the simulated three-dimensional calibration pattern, poses may be selected from only that portion of the camera's field of view which is expected to be typically used in operation of the camera.

  • Patent number: 10853941
    Abstract: The present invention discloses a registration method and system for a non-rigid multi-modal medical image. The registration method comprises: obtaining local descriptors of a reference image according to Zernike moments of order 0 and repetition 0 and Zernike moments of order 1 and repetition 1 of the reference image; obtaining local descriptors of a floating image according to Zernike moments of order 0 and repetition 0 and Zernike moments of order 1 and repetition 1 of the floating image; and finally obtaining a registration image according to the local descriptors of the reference image and the floating image. In the present, by using self-similarity of the multi-modal medical image and adopting the Zernike moment based local descriptor, the non-rigid multi-modal medical image registration is thus converted into the non-rigid mono-modal medical image registration, thereby greatly improving its accuracy and robustness.
