  • Patent number: 11178428
    Abstract: An image splicing method includes obtaining a first overlapping image and a second overlapping image from a first image and a second image to-be-spliced. The method also includes determining a motion vector from each pixel in the first overlapping image to a corresponding pixel in the second overlapping image, to obtain an optical flow vector matrix; according to the optical flow vector matrix, remapping the first overlapping image to obtain a first remapping image, and remapping the second overlapping image to obtain a second remapping image; and merging the first remapping image and the second remapping image, to obtain a merged image of the first overlapping image and the second overlapping image, and determining a spliced image of the first image and the second image according to the merged image.

  • Publication number: 20190323122
    Abstract: An isolation equipment for a precipitation chamber, for separating an inner cavity and an outer cavity of the precipitation chamber, includes a partition mechanism for closing the inner cavity. The partition mechanism includes a main door panel covering an opening of the inner cavity and an elastic device arranged to press the main door panel towards the inner cavity to tightly seal the inner cavity.
