Problems solved by technology

But the premise of using this method is that the stereo camera must be calibrated before the 3D film is shot, otherwise the method will be invalid
For most 3D movies in reality, the camera parameters cannot be obtained. In this case, the method of uncalibrated situation can only be used

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the purpose and effects of the present invention will become more apparent.

[0032] figure 1 A flow chart of the method for stereoscopic image correction according to the present invention is given.

[0033] The stereoscopic image correction method based on viewpoint synthesis described in the present invention is carried out for stereoscopic images. A stereoscopic image is composed of two views called left view and right view respectively. Stereo images are generally taken by a stereo camera, which consists of two cameras, a left camera and a right camera, wherein the left camera is used for shooting the left view, and the right camera is used for shooting the right view. Stereoscopic images can also be captured by a single camera through time-sharing horizontal displacement, and at this time the left and right cameras correspon...

Abstract

The invention discloses a stereo image vertical parallax eliminating method based on viewpoint synthesis. The stereo image vertical parallax eliminating method comprises the four sequent steps of carrying out epipolar rectification in a traditional method on an original stereo image to obtain an initially-rectified stereo image, matching the initially-rectified stereo image in a three-dimensional mode to obtain a corresponding horizontal parallax image, calculating according to the projection relation to obtain a horizontal parallax image and a vertical parallax image corresponding to the original stereo image and carrying out viewpoint synthesis based on the horizontal parallax image and the vertical parallax image of the original stereo image to obtain a rectified stereo image. The stereo image vertical parallax eliminating method is mainly characterized by introducing a viewpoint synthesis technique, eliminating the vertical parallax of the stereo image and meanwhile reducing projection distortion in a rectifying process.

Description

technical field [0001] The invention relates to a method for eliminating vertical parallax of stereoscopic images based on viewpoint synthesis. Background technique [0002] 3D movies have developed rapidly in recent years. Generally speaking, 3D movies can be obtained through computer animation synthesis, 2D to 3D technology, and stereo camera shooting, among which shooting with stereo cameras will be the mainstream of 3D movie development in the future. A stereo camera usually consists of two left and right cameras, which are designed to be arranged in parallel with their optical axes. However, due to the precision of mechanical alignment, the stereoscopic images or videos obtained cannot be completely aligned. When the stereo camera lens needs to be stretched, the alignment problem is further complicated by the desynchronization of motion between the left and right cameras. All of these have caused more or less vertical parallax between the left and right views of the ...
