Rotating disc device, semispherical photographing system capable of adjusting center of sphere and height and semispherical photographing method thereof

Abstract

The invention discloses a rotating disc device, a semispherical photographing system capable of adjusting the center of sphere and the height and a semispherical photographing method thereof. The rotating disc device comprises a rotating disc, a first horizontal motion mechanism, a second horizontal motion mechanism and a rotating mechanism which are arranged from the top to the bottom in turn. The first horizontal motion mechanism, the second horizontal motion mechanism and the rotating mechanism are connected with a control device. The motion direction of the first horizontal motion mechanism and the second horizontal motion mechanism is crossed at the angle of 90 degrees. The semispherical photographing system comprises a photographing device, the rotating disc device, a rocker arm device and the control device which is connected with the photographing device, the rocker arm device and the rotating disc device. The photographing device is arranged on the rocker arm device, and the lens faces the center line perpendicular to the center of circle of the rotating disc device. The alignment central position of the photographed object to the photographing device and the initial height of the arc motion trajectory can be automatically adjusted so that the photographing device is enabled to perform relative motion around the photographed object on the semispherical surface, and automatic photographing and automatic image processing can be realized.

Description

technical field [0001] The invention relates to a hemispherical photography system and method, in particular to a turntable device, a hemispherical photography system and method capable of adjusting the center and height of the sphere, and belongs to the technical field of photography. Background technique [0002] Panoramic photography (Panoramic photography) is a technology that uses a picture with a large viewing angle to virtually present a real scene to the user. Due to the limitations of lens technology, it is usually necessary to take continuous pictures from multiple angles. Through image deformation correction and image stitching technology, the multi-angle pictures are synthesized into a panoramic image with a large perspective. For the introduction of this technology, see the definition of the wiki website. [0003] The invention patent application with the Chinese patent application number 201310048011.2 discloses a hemispherical panoramic imaging device and meth...

AI Technical Summary

Problems solved by technology

The problems and shortcomings of this technology are: 1) manufacturing hemispherical shells, especially large-radius hemispherical shells, requires relatively high processing technology and increases costs; 2) multiple cameras need to be installed to shoot at the same time, and It will increase the cost; 3) From the perspective of the uniformity of photography light, it is more difficult for cameras at all shooting angles to obtain consistent exposure, which will increase the difficulty of later image stitching

The problems and disadvantages encountered in the actual use process are: 1) When placing the object in the middle of the turntable, it needs manual adjustments many times to move the object to the center of the turntable, which consumes a lot of time; 2) The height of the object to be photographed is not the same When using the camera, the starting height of the camera cannot be adjusted, resulting in an unnatural viewing angle of the photo, or even deformation.
