Abstract: Provided is a method for playing a panoramic picture, the method comprising: acquiring a corresponding non-planar panoramic picture according to a picture acquisition instruction; acquiring picture content from the non-planar panoramic picture, and determining a main presentation axis and a presentation centre of the picture content; creating a cylindrical projection plane by using the main presentation axis and the presentation centre, wherein a cylinder extension direction of the cylindrical projection plane is substantially perpendicular to the main presentation axis, and the centre of the cylindrical projection plane essentially overlaps the presentation centre; converting the non-planar panoramic picture into a cylindrical panoramic picture with the cylindrical projection plane; and executing a playing operation on the cylindrical panoramic picture by using a planar display apparatus.
Abstract: The present invention provides a high dynamic range video shooting method, comprising: acquiring corresponding images by means of shooting lenses of a multi-lens panoramic camera; determining corresponding image synthesis weights of image pixel blocks according to pixel color gray scale variations, pixel color gray scale differences and pixel color gray scale offsets of the image pixel blocks of each shot image; forming a high dynamic range panoramic shot image based on the image synthesis weights of the image pixel blocks of each shot image; and splicing all the high dynamic range panoramic shot images.
Abstract: Provided in the present invention is a panoramic image acquisition device, which comprises a body, a plurality of cameras, a image extraction processor, and an image combination processor; the cameras being provided on the body at an approximate spacing between the human eyes, for acquiring partial pictures of a plurality of different shooting angles; the image extraction processor being connected to the plurality of cameras, for acquiring, on the basis of the human eyes simulating the orientations of the cameras, left-eye pictures and right-eye pictures of the partial pictures corresponding to the cameras; the image combination processor being connected to the image extraction processor, for combining the left-eye pictures of all the partial pictures into a left-eye panoramic picture and combining the right-eye pictures of all the partial pictures into a right-eye panoramic picture.
Abstract: The present invention provides a photographing synchronization method for performing a synchronous photographing operation on a plurality of cameras using any one of cameras in a multi-camera system. The method comprises: obtaining all cameras in a current synchronous network by means of network broadcast; obtaining signal transmission delays between the cameras; generating a synchronous photographing instruction of each camera according to the signal transmission delays between the cameras; and sending the synchronous photographing instructions to particular cameras over a wireless network.
