Document Type and Number:
WIPO Patent Application WO/2019/080047
Kind Code:
A1
Abstract:
Disclosed in the present application is an implementation of an augmented reality image. The implementation method of the augmented reality image comprises: obtaining a frame of image and an attitude direction of a camera when shooting the frame of image; determining a framing area in a three-dimensional Cartesian coordinate system when the camera is shooting in a shooting manner; determining a two-dimensional graph in the framing area, and acquiring three-dimensional coordinates of a position reference point of each determined two-dimensional graph; adjusting the attitude for each determined two-dimensional graph on the basis of a rotation reference point of the two-dimensional graph, so that the two-dimensional graph is at a predetermined angle with the attitude direction, and acquiring the three-dimensional coordinates of the position reference point of the two-dimensional graph whose attitude is adjusted; and through perspective projection transformation, projecting the three-dimensional coordinates of the position reference point of the two-dimensional graph into two-dimensional coordinates on a corresponding planar projection area, and rendering the two-dimensional graph on the frame of image according to the two-dimensional coordinates.
