Problems solved by technology

[0003] However, although the two-dimensional display method can display all the image information, it lacks the three-dimensional effect, and although the three-dimensional display method has the three-dimensional effect, it can only display the partial image information. Both of these two display methods have defects.

Abstract

The invention provides a video image display method, device and system. The method comprises the steps of determining a two-dimensional correction image and a three-dimensional perspective image corresponding to a video image collected by a camera; and fusing the two-dimensional correction image and the three-dimensional perspective image by using an interpolation variable, and displaying the fused image. The two-dimensional correction image and the three-dimensional perspective image are fused and displayed by using the interpolation variable, so that not only can all image information be displayed, but also animation transition from 3D to 2D or from 2D to 3D can be realized, and relatively strong visual impact is brought to a user.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a video image display method, device and system. Background technique [0002] Fisheye video is a video image collected by an ultra-wide-angle lens. Its viewing angle ranges from 220 degrees to 230 degrees, and the picture distortion effect is strong. When performing two-dimensional (2D) display, it is necessary to correct the distortion of the video image according to the camera imaging principle, and the entire picture can be displayed on the screen by adjusting the image area. When performing three-dimensional (3D) display, it is necessary to map the image coordinates of the video image and the three-dimensional coordinates of the three-dimensional model, and the user watches the video image by setting a three-dimensional viewing angle. [0003] However, although the two-dimensional display method can display all image information, it lacks three-dimensiona...
