A dual-mode fine-tuning 3D image shooting bracket

Abstract

The invention discloses a dual-mode fine-tuning 3D image shooting bracket, which includes a bracket body, a camera fixing component, and a dual-mode precise adjustment mechanism for the interpupillary distance and the converging surface; the dual-mode precise adjustment mechanism for the interpupillary distance and the converging surface includes longitudinal guide rails, An active longitudinal slide block, a driven longitudinal slide block, an operating rod, a horizontal slide block, a pupil distance fixing ring, a converging surface adjusting ring, a converging surface fixing button and an adjusting link. The present invention realizes the adjustment of the interpupillary distance by adjusting the operating rod when tightening the fixing button of the converging surface and loosening the fixing ring of the interpupillary distance; It can realize the adjustment of the converging surface, realize the fine adjustment of the two machines synchronously, and thus realize the fine adjustment of the two parameters of the interpupillary distance and the converging surface in the simplest way, and effectively improve the visual experience of the image.

Description

technical field [0001] The invention relates to a double-mode fine-tuning 3D image shooting bracket. Background technique [0002] The interpupillary distance, derived from the distance between the pupils of the human eyes, is usually 6.5 to 8 cm. It is extended to the axial distance of the dual lenses during 3D shooting. Due to the physical size limitation of the camera or video camera, the IPD of the shooting bracket is usually larger than the IPD of the human body, but it should be as close as possible to the IPD of the human body to improve the visual experience of the image. [0003] The converging surface originates from the interweaving point of binocular sight and observed object when people observe things with binoculars. It is extended to the intersection point of the center point of the photosensitive element of the dual lens and the center point of the object being photographed during 3D shooting. The closer the object to be photographed is to the camera, the l...

Problems solved by technology

At present, the special 3D shooting equipment on the market is extremely expensive and scarce. Usually, two cameras or cameras are fixed parallel to each other or up and down to form a dual-lens shooting system.

However, the bracket generally used to fix the two cameras only has the function of adjusting the interpupillary distance (that is, the distance between the axes of the two lenses), and its adjustment accuracy is not high. At the same time, it does not have the function of adjusting the convergence surface, so the shooting effect is not good. Negative experiences that easily cause dizziness
