Three-dimensional image shooting device

Abstract

The invention discloses a three-dimensional image shooting device comprising a guide rail (1), a bracket (2) for supporting the guide rail, a worktable (3), a driving motor (4), a camera and a controller. The worktable (3) is arranged on the guide rail (1) and can slide along the guide rail (1), the driving motor (4) drives the worktable (3) to slide, the controller (8) is electrically connected with the motor (4), the guide rail (1) is a linear guide rail, and the camera (7) is fixedly connected with the worktable (3). By adopting the three-dimensional image shooting device, the camera slides on the linear guide rail along with the worktable and continuously shots a plurality of images at different angles; the vision angles of the obtained images can be adjusted through software so as to meet the need for combining three-dimensional images; the linear guide rail is adopted to decrease the cost of the shooting device and omit the fine tuning of the angle and the focus as compared with a curve guide rail; and the camera and the worktable are directly fixed to avoid accuracy error and shooting joggling brought by the rotation of a camera in the prior art and ensure good shooting effect.

Description

Technical field: [0001] The invention relates to the field of image capturing, in particular to a stereoscopic image capturing device. Background technique: [0002] When people use two eyes to observe objects, they have a three-dimensional sense because the distance between the pupils of the two eyes is about 6 to 7 cm. When looking at anything with the eyes, the angles of the two eyes will not be exactly the same; although the two eyes see The gap between east and west is very small, but it is transmitted to the brain through the retina, resulting in a sense of distance and thus a three-dimensional effect. According to this principle, if the same image is used to create two images with a slight angle difference by using the visual difference of the two eyes, and then let the two eyes see them separately, the brain can produce a stereoscopic image through the retina. At present, most of the stereoscopic images are taken by dual-lens video cameras or two cameras. The dual-l...

However, since the track of the above-mentioned prior art photographing device is arc-shaped, and the cost of manufacturing the arc-shaped track is relatively high, and requires high manufacturing precision, the arc-shaped track also requires complicated angles during manufacture and use. In addition, the camera not only moves with the slider, but also rotates under the drive of the rotating device. Various forms of movement will inevitably bring errors to the camera's shooting, thus affecting the shooting effect
