Device and method for tilt-shift stereoscopic photography

Abstract

The invention relates to a device and method for tilt-shift stereoscopic photography. In a process that a camera moves along a linear guide, a driving module can control a tilt-shift lens installed on the camera to move along a direction opposite to the direction in which the camera moves along the linear guide, so that a focus of a photographed object is in a constant position in composition of the camera. The device and method for tilt-shift stereoscopic photography is simple and efficient; the resolution of the camera isn't lost during the composition; the photographed frame is smooth and stable; the obtained stereoscopic image is free of vertigo; and the requirement of a safety shutter during moving photography and the jelly effect are reduced.

Description

technical field [0001] The invention relates to a method for shooting stereoscopic photos, which can be used for shooting multi-viewpoint naked-eye stereoscopic photos. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] At present, the shooting of naked-eye three-dimensional photos is mainly realized by moving a single-lens camera on a slide rail for continuous shooting. On this basis, three shooting methods have been developed: arc slide rails, linear slide rails, and rotary pan-tilt linear slide rails. [0004] The advantage of the arc slide rail is that when the focus of the subject 11 is at the center of the arc slide rail 14, the sequence images taken can be directly synthesized into a stereoscopic photo output without the process of re-alignment adjustment, such as Figure 1a shown. The disadvantages have t...

Problems solved by technology

The disadvantages have two points. One, the focus of the subject 11 is not in the center of the circle, that is, when the distance between the subject 11 and the arc slide rail 14 is not equal to the radius of curvature of the arc slide rail 14, the sequence images still need to be reset. Alignment adjustment; second, when the camera 13 moves on the arc slide rail 14, its optical axis 12 changes, and the perspective relationship also changes. The size and position of the sequence images of , in addition to the horizontal parallax required to produce a stereoscopic effect, there are also obvious rotation and scaling, which brings dizziness, such as figure 2 shown

The disadvantage is that when the camera 23 moves on the linear slide rail 24 of the rotating pan / tilt, its optical axis 22 changes, and the perspective relationship also changes. The size and size of the object 11 in the field of view in different sequence images The position changes, similar to the arc slide rail, except for the horizontal parallax, there is also obvious rotation and scaling, which brings dizziness, such as figure 2 shown

There are two disadvantages. First, due to the horizontal movement of the camera 33, the subject 11 gradually moves out of the field of view, resulting in a lack of picture, such as Figure 4 Second, in order to make up for the missing picture, a wider lens can only be used to capture a larger field of view to crop the alignment sequence image, which will inevitably lose the resolution of the camera
