Embodiment Construction

[0029] In the prior art, cameras all use lenses as lenses to achieve the purpose of imaging. When light in all directions passes through the lens, it will be deflected, changing the direction of light propagation. But there is a point on the lens, when light in any direction passes through this point, the propagation direction of the light remains unchanged, that is, the outgoing direction and the incident direction are parallel to each other. This point is called the optical center of the lens, or optical center for short. In the present invention, the calibration position of the camera is determined based on the optical center of the lens.

[0030] The basic idea of ​​the present invention is: use dual cameras to shoot the calibration object at the same time, respectively obtain the calibration image for the left eye and the calibration image for the right eye; determine the translation error between the dual cameras according to the position of the calibration object in the...

Abstract

The invention discloses a method for correcting a translation error between images shot by two cameras, and the method comprises the following steps: simultaneously shooting a calibrated object by two cameras so as to respectively obtain a left-eye calibrated image and a right-eye calibrated image; determining a translation error between the two cameras according to the positions of the calibrated object in the two calibrated images, and then storing the translation error; and correcting the images shot by the two cameras according to the stored translation error. The invention also discloses a device for correcting a translation error of images shot by two cameras. By utilizing the method and device disclosed by the invention, the translation error between the two cameras can be eliminated effectively, so that a viewer can see clear stereo images.

Description

technical field [0001] The invention relates to a stereo shooting technology with dual cameras, in particular to a method and device for correcting translation errors of images captured by dual cameras. Background technique [0002] In the prior art, the stereoscopic display of pictures or images is realized by utilizing the parallax characteristic of binoculars, and the methods mainly include: color division method, light division method, time division method and grating method, etc. Although the specific implementation methods are different, the basic starting point is the same, and the principles are generally similar, that is, using two cameras placed side by side to represent the left eye and right eye of a person, and using the two cameras to simultaneously shoot two images with a slight horizontal parallax. picture. When projecting, the left-eye film and the right-eye film are loaded into the left-eye projection device and the right-eye projection device respectively...
