Method for playing panoramic picture and apparatus for playing panoramic picture

A panoramic picture playing method, comprising:

• acquiring a corresponding non-planar panoramic picture according to a picture acquisition instruction, wherein the non-planar panoramic picture is a panoramic picture having a non-planar projection plane;
• acquiring a picture content in the non-planar panoramic picture, and determining a main presentation axis and a presentation center of the picture content;
• establishing a cylindrical projection plane by using the main presentation axis and the presentation center, wherein a cylindrical extending direction of the cylindrical projection plane is perpendicular to the main presentation axis, and the center of the cylindrical projection plane is overlapped with the presentation center;
• converting the non-planar panoramic picture into a cylindrical panoramic picture having the cylindrical projection plane;
• playing the cylindrical panoramic picture by using a flat-panel display device;
• receiving a picture adjustment instruction, and acquiring a current display region of the cylindrical panoramic picture in the entire panoramic picture according to the picture adjustment instruction;
• determining a preset display region of the entire panoramic picture from standby display regions according to the current display region;
• determining picture adjustment parameters of the cylindrical panoramic picture according to the current display region of the cylindrical panoramic picture in the entire panoramic picture and the preset display region;
• and
• adjusting the cylindrical panoramic picture to the preset display region based on the picture adjustment parameters, wherein a center line of the preset display region is overlapped with a center line of the entire panoramic picture,
• wherein a main presentation direction is the same as a horizontal presentation direction of the flat-panel display device;
• the non-planar panoramic picture comprises a panoramic picture having a spherical projection plane, a conical projection plane, a cubic projection plane or a fisheye projection plane.
