Description

{RIG FOR PHOTOGRAPHING MULTIVIEW IMAGES}, a combination of a horizontal method and an orthogonal method,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a multi-viewpoint photography rig, and more particularly to a multi-viewpoint photography rig combined with a horizontal method and an orthogonal method.

As interest in stereoscopic images has recently increased, cameras or devices for capturing stereoscopic images have been developed.

In general, a multi-view imaging rig refers to a device capable of adjusting the binocular disparity and / or the main time of the camera while fixing a plurality of cameras.

Specifically, a horizontal type rig is a rig that can mount a left-eye camera and a right-eye camera with a certain distance on a plane with respect to a subject, so that a left-eye camera and a right-eye camera directly receive light of a subject, It is a league of the way.

The orthogonal type rig has a half mirror that transmits or reflects light of a subject and separates the left eye camera from the other optical axis among the two optical axes output by the half mirror, The left eye camera and the left eye camera receive the light of the object indirectly through the half mirror to acquire an image.

These leagues should be able to fix the mounted cameras tightly and adjust the position of the camera precisely to adjust the binocular disparity and convergence angle between the images acquired by the left and right eye cameras do.

However, due to the nature of the stereoscopic image taking, there are many movements of the shooting location, so it is not easy to precisely adjust the position (binocular disparity and / or the main time) between the cameras during shooting. Due to the difficulty in precise positional adjustment, image alignment between the left eye and right eye images is not accurately performed. As a result, the image quality of the stereoscopic image is deteriorated, a posterior operation is separately required, Or dizziness may be caused.

Also, the number of cameras used to obtain a more precise multi-view image is increased. In the past, since a plurality of cameras are installed in a horizontal direction, the space occupied by the camera and the league increases as the number of cameras increases. .

And, as the subject gets close to the camera, it is difficult to capture the distance between the cameras installed in the league by narrowing the binocular distance by mutual interference.

When the user rotates the second knob 431b, the worm shaft 432 and the second knob 431b rotate at the same angular velocity. However, if the user rotates the first knob 431b, The rotation of the shaft 432 and the first knob 431a is not implemented equally. That is, when the gear ratio of the first gear 431aa to the third gear teeth 431ac is adjusted, the worm shaft 432 may be rotated one turn when the first knob 431a is rotated by a half turn, The worm shaft 432 may be rotated by one half when the first knob 431a is rotated one turn.

With this precise control, the present invention can consequently control the binocular disparity and / or the main time of the camera mounted on the fourth stage 450 more precisely.

The fourth stage 450 is disposed to slide on the front surface of the third stage 440, and a third camera may be mounted. The fourth stage 450 is formed with tapered portions 451 which are inclined so as to be wider toward the rear side and the third stage 440 is provided with a guide groove And both side surfaces of the guide groove 441 are formed to correspond to the inclination of the tapered portion 451.

The depth of the tapered portion 451 may be greater than the depth of the tapered portion 451. The height of the tapered portion 451 may be greater than the depth of the tapered portion 451.

In this case, a fixing lever 442, which is disposed on the front surface of the third stage 440 so as to rotate axially and restricts the movement of the fourth stage 450 by pressing the tapered portion 451 of the fourth stage 450, And the movement of the fourth stage 450 can be restricted by the user pressing the tapered portion 451 of the fourth stage 450 by rotating the fixed lever 442.
