A three-dimensional camera is a camera capable of simultaneously acquiring a left eye image and a right eye image of a subject using two cameras. A three-dimensional camera generally includes a left eye image camera that acquires a left eye image of a subject, a right eye image camera that acquires a right eye image of a subject, and the A left eye video camera and a right eye video camera are mounted on a stereoscopic camera rig.

Also, the three-dimensional camera rig is classified into a horizontal three-dimensional camera rig and an orthogonal three-dimensional camera rig according to the form in which the cameras are mounted or the use of a half mirror.

In addition, the horizontal stereoscopic camera rig is a camera rig that can mount the cameras spaced apart from each other by a predetermined distance toward the subject on a plane, the orthogonal stereoscopic camera rig is any one of the cameras looking at the subject The other camera is a camera rig which can be mounted such that the camera and the optical axis are orthogonal to each other so as to capture an image of a subject reflected by a half mirror placed on the optical axis of the one camera.

On the other hand, when the left eye image and the right eye image are viewed as a stereoscopic image through a stereoscopic image display, the stereoscopic feeling that a person feels is very different depending on whether image alignment is performed between the images.
