Method and device for shooting stereo images by automatically correcting parallax error

Abstract

The invention relates to a method and a device for shooting stereo images by automatically correcting a parallax error. The method comprises the following steps of: acquiring scenery distance information; calculating parallax error correcting data; automatically adjusting space or an angle of a camera lens; completing automatic focus and shooting; and synthesizing the stereo images. The method and the device make shooting equipment shoot high-quality stereo images in various situations by automatically correcting the parallax error during shooting, and avoid the defects that unreasonable parallax errors exist in the shot stereo images because of over short scenery distance or overlarge lens focus of the conventional stereo image shooting technology so as to generate feelings of dizziness and eye discomfort. The invention particularly provides the following three kinds of schemes for correcting the parallax error: automatically adjusting space, automatically adjusting angle by using single lenses, and automatically adjusting the angle by using double lenses. The device for implementing the scheme can be arranged in stereo shooting mobile phones, stereo cameras and stereo video cameras to shoot the stereo images by automatically correcting the parallax error.

Description

technical field [0001] The invention relates to a stereoscopic image shooting technology, in particular to a stereoscopic image shooting method for automatically correcting parallax and a stereoscopic image shooting device for realizing the method. Background technique [0002] There is a certain distance between the left and right eyes of a person, resulting in a certain horizontal displacement and angular displacement of the image of the scene in the two eyes. The brain processes these two kinds of parallax information to produce a three-dimensional effect. The two-dimensional images can be viewed by the left eye and the right eye respectively, and the viewer can restore the three-dimensional feeling of the shooting scene. Present stereo camera mobile phone, stereo camera, stereo video camera use all this principle, generally adopt the dual-lens structure of fixed pitch and angle to shoot stereo images. However, because the human eye needs to keep the parallax within a ce...

AI Technical Summary

Problems solved by technology

However, because the human eye needs to keep the parallax within a certain range to view it normally, and the dual-lens structure with fixed spacing and angle cannot timely correct the parallax according to the distance of the scene and the focal length of the lens, so the existing stereoscopic image shooting equipment generally has some The problems caused by unreasonable parallax are mainly reflected in: 1. When the distance of the scene decreases or the focal length of the lens increases, the parallax of the stereoscopic image increases accordingly. When the parallax is greater than the range that the human eye can comfortably watch, it is easy to Make the viewer feel dizzy and eye discomfort; 2. When the distance of the scene increases or the focal length of the lens decreases, the parallax of the stereoscopic image will decrease accordingly, resulting in the weakening of the image's stereoscopic effect; 3. Due to the short distance or the focal length In very large cases, the parallax of the image is greater than the range that the human eye can normally see, so the existing stereoscopic image shooting equipment is often unable to perform macro shooting, which reduces the scope of application of the shooting equipment

[0003] In the field of personal application, the existing stereoscopic image shooting equipment cannot adapt to the changing shooting environment. The problem of too large or too small parallax caused by the distance of the scene and the focal length of the lens leads to uneven quality of the stereoscopic image, which is not conducive to the stereoscopic image.
