Photographing system for viewing 3d images with naked eyes and using method thereof

An image photographing system for viewing 3D images with naked eyes, including an L-shaped frame (1), wherein, a top end of a vertical portion (1a) of the L-shaped frame (1) successively at equal intervals providing with:

• an intermediate photographing mechanism (3) configured for projecting a laser beam to the object to be photographed to generate a diffuse reflection spot and photographing the object;
• a left photographing mechanism (2) and a right photographing mechanism (4) respectively configured for locating the object through the diffuse reflection spot generated on the object by the laser beam projected by the intermediate photographing mechanism and photographing the object;
• a support plate (6) is provided above a horizontal portion (1b) of the L-shaped frame (1);
• a left driving mechanism (9) and a right driving mechanism (10) configured for driving the left photographing mechanism (2) and the right photographing mechanism (4) to swing left and right are provided at positions, corresponding to the left photographing mechanism and the right photographing mechanism, on an upper end face of the support plate (6), respectively;
• a guide post (5) and a vertical driving servo motor (8) are vertically arranged on the horizontal portion (1b) of the L-shaped frame (1);
• a driving shaft of the vertical driving servo motor (8) is connected to a driving lead screw (7), and the driving lead screw (7) is connected to the support plate (6) through a screw hole in a penetrated manner;
• wherein, the guide post (5) penetrates through the support plate (6);
• and, the support plate (6) drives the left driving mechanism (9) and the right driving mechanism (10) to move up and down by moving up and down along the guide post (5) under the drive of the driving lead screw (7), so as to drive the left photographing mechanism (2) or the right photographing mechanism (4) to swing up and down.
