However, one or more embodiments may be implemented without the details. In other cases, to simplify the accompanying drawings, well-known structures and apparatuses may be shown simplistically.

Referring to FIG. 1, an embodiment of the present disclosure provides a 3D photographing apparatus, comprising at least three cameras; a first camera 10 of the at least three cameras is taken as a center, and the remaining cameras of the at least three cameras are arranged at a periphery of the first camera 10; and connecting lines between the remaining cameras and the first camera 10 form at least one right angle, wherein any two of the at least three cameras are capable of photographing a 3D image by cooperation.

After a change in a posture of camera, original cameras cooperating to photograph a 3D image may be switched with other cameras to photograph the 3D image.

As shown in FIG. 1, the 3D photographing apparatus comprises three cameras, only including a first camera 10, a second camera 11 and a third camera 12. In this case, a connecting line between a center B of the first camera 10 and a center A of the second camera 11 and a connecting line between the center B of the first camera 10 and a center C of the third camera 12 form a right angle; and any two of the at least three cameras are capable of photographing a 3D image by cooperation.

The 3D photographing apparatus shown in FIG. 1 comprises four cameras: a first camera 10, and the remaining cameras, including a second camera 11, a third camera 12, and a fourth camera 13 (13′), wherein the connecting line between the center B of the first camera 10 and the center A of the second camera 11 and the connecting line between the center B of the first camera 10 and the center C of the third camera 12 form a right angle.

When the first camera 10 and the third camera 12 are adopted to photograph a 3D image, the first camera 10 and the second camera 11 are switched to photograph the 3D image when the posture of camera changes by 90°. A difference based on clockwise rotation and counterclockwise rotation is to configure the first camera 10 or the second camera 11 to photograph a left-eye image, and correspondingly configure the first camera 10 or the second camera 11 to photograph a right-eye image.

A connecting line between a center D (D′) of the fourth camera 13 (13′) and the first camera 10 and a connecting line between the second camera (third camera) and the first camera 10 may form an angle of 45° or the like, which is not limited here. When the change in the posture of camera is clockwise rotation by 135°, the first camera 10 and the fourth camera 13 are switched to photograph the 3D image. When the change in the posture of camera is clockwise rotation by 45°, the first camera 10 and the fourth camera 13′ are switched to photograph the 3D image.

The 3D photographing apparatus may comprise the fourth camera 13 and the fourth camera 13′ at the same time; and a connecting line between the center D of the fourth camera 13 and the center B of the first camera 10 is at an angle of 90° to a connecting line between the center D′ of the fourth camera 13′ and the center B of the first camera 10.

15. A computer program product, comprising a computer program stored on a non-transitory computer-readable storage medium, wherein the computer program comprises program instructions which, when executed by a computer, cause the computer to execute the method of claim 8.
16. The apparatus according to claim 1, wherein the remaining cameras comprise a second camera, a third camera, and a fourth camera, wherein a connecting line between a center of the first camera and a center of the second camera and a connecting line between a center of the first camera and a center of the third camera form a right angle.
17. The apparatus according to claim 3, wherein the remaining cameras further comprise a sixth camera; and a connecting line between the sixth camera and the third camera is perpendicular to a connecting line between the third camera and the first camera.
18. The apparatus according to claim 4, wherein the remaining cameras further comprise a sixth camera; and a connecting line between the sixth camera and the third camera is perpendicular to a connecting line between the third camera and the first camera.
19. The method according to claim 10, wherein the method is adapted to a scene that the remaining cameras further comprise a fifth camera, the fifth camera is arranged at an other side of the first camera relative to the third camera and a connecting line between the fifth camera and the first camera is on a same straight line as a connecting line between the third camera and the first camera; adjusting a cooperation mode of the at least three cameras in response to a change of the posture comprises: configuring the first camera, and the third camera or the fifth camera to respectively acquire a left-eye image and a right-eye image when a posture of the 3D display terminal does not change; andconfiguring the first camera, and the second camera or the fourth camera to respectively acquire the left-eye image and the right-eye image when a posture of the 3D display terminal is rotation by 90°.
20. The method according to claim 19, wherein adjusting a cooperation mode of the at least three cameras in response to a change of the posture comprises: switching the first camera and the third camera or the fifth camera to respectively acquire the right-eye image and the left-eye image when a posture of the 3D display terminal is rotation by 180°.
