The invention discloses a method for optimizing the pixel position distribution of a panoramic image or video in the technical field of computer multimedia information processing. The specific steps of the method for optimizing the pixel position distribution of a panoramic image or video are as follows: Get the pixel values of coordinate points (x, y, z), and store these pixel values on the rectangular plane with pixels; S2: deduce the latitude value of each row of pixels on the spherical surface; S3: use S(β ) function to control the concentration of pixels near the equator; S4: map the pixels of the moment plane to the spherical surface for playback, and the present invention makes the distribution of the pixels of the spherical panoramic video on the spherical surface more optimized, that is, the pixels near the spherical equator denser, while the pixels near the two poles of the spherical surface are sparser, which is more in line with the viewing habits of users.
Description
technical field [0001] The invention relates to the technical field of computer multimedia information processing, in particular to a method for optimizing the pixel position distribution of panoramic images or videos. Background technique [0002] Panoramic video is a form of expression of virtual reality (VR, Virtual Reality), which can present a 720° scene to the audience, so that the audience can get an immersive viewing experience. At present, panoramic video often adopts the method of spherical projection. When there is a spherical display device, the panoramic video using the spherical projection method can be directly played on the spherical display device. When there is no spherical display device but only a flat display device, a compromise playback method can be used, that is, assuming that the flat display device is a window through which the user can only see a part of the panoramic view. Users can control their viewing angle in the panoramic view by dragging ...
