Description
Technical field
The present invention relates to a kind of method of taking stereoscopic photograph, the method can be used for the shooting of multiple views bore hole stereoscopic photograph.
Background technology
Below background of related of the present invention is described, but these explanations might not form prior art of the present invention.
At present, the shooting of bore hole stereoscopic photograph mainly adopts the mode of single-lens camera mobile continuous shooting on slide rail to realize, and has developed camber line slide rail, line slide rail, rotary head line slide rail three kinds of styles of shooting on this basis.
The advantage of camber line slide rail is, when the focus of subject 11 is in the circle centre position of camber line slide rail 14, the sequence image of shooting can export without the direct compound stereoscopic photo of process of contraposition adjustment again, as shown in Figure 1a.Weak point has 2 points, one, and the focus of subject 11 is not in the center of circle, and when namely subject 11 is not equal to the radius-of-curvature of camber line slide rail 14 with the distance of camber line slide rail 14, sequence image still needs contraposition again to adjust; They are two years old, when camera 13 moves on camber line slide rail 14, its optical axis 12 changes, perspective relation also changes, and because of " near big and far smaller ", the size of the subject 11 in visual field in different sequence images and position all change, except producing the horizontal parallax needed for stereoscopic sensation, also exist and significantly rotate convergent-divergent, bring spinning sensation, as shown in Figure 2.
The advantage of rotary head line slide rail is, in the process of camera 23 movement on rotary head line slide rail 24, camera lens can point to the focus of subject all the time, for the subject 11 of different distance, can accomplish that sequence chart central point is unified, sequence image does not need contraposition to adjust, as shown in Figure 1 b.Weak point is, when camera 23 moves on rotary head line slide rail 24, its optical axis sends out 22 raw changes, perspective relation also changes, and the size of the subject 11 in visual field in different sequence images and position all change, similar to camber line slide rail, except horizontal parallax, also exist and significantly rotate convergent-divergent, bring spinning sensation, as shown in Figure 2.
The advantage of line slide rail is, when camera 33 moves on line slide rail 34, optical axis 32 does not change, perspective relation is constant, and as shown in Figure 3, the subject 11 in visual field is in different sequence images, except horizontal parallax, there is not rotation convergent-divergent, stereoscopic photograph viewing comfort level is high.Weak point has 2 points, one, and due to moving horizontally of camera 33, subject 11 shifts out visual field gradually, causes the disappearance of picture, as shown in Figure 4; Its two, in order to make up the picture of disappearance, the larger visual field of wider lens shooting can only be adopted to cut bit sequence image, the resolution of inevitable loss camera.
Therefore, a kind of solution that can solve the problem is needed in prior art.
