Stereo video shooting device

Abstract

The invention discloses a stereo video shooting device, which can real-time adjust a distance and an included angle between left and right cameras in a shooting process according to different shooting conditions. The invention adopts a technical scheme that: the shooting device comprises a hanging piece, two upright arms and a rotary platform, wherein the hanging piece is provided with a controller used for receiving an adjustment command related to the cameras; the top ends of the upright arms are connected with both ends of the hanging piece respectively; and both ends of the rotary platform are connected with the bottom ends of the two upright arms, the rotary platform is provided with a guide rail and two adjusting plates arranged on the guide rail, the two cameras are arranged on the two adjusting plates respectively, and the controller sends a command to a motor and then adjusts the positions of the two adjusting plates by using a screw rod, so that the included angle and the base length between the two cameras are adjusted in real time.

Description

technical field [0001] The invention relates to an image shooting device, in particular to a stereoscopic image shooting device. Background technique [0002] Three-dimensional stereoscopic film and television is becoming more and more mainstream in the field of film and television. Compared with two-dimensional flat film and television, its image realism has been greatly improved. The principle of stereoscopic film and television is: the human eye has a three-dimensional sense when viewing objects. This is because the distance between the pupils of the two eyes is about 65mm, and the visual images received by the left and right eyes are different when viewing the same object. Yes, it is transmitted to the brain through the retina, and the brain uses this tiny gap to produce a sense of distance, thus creating a three-dimensional effect. [0003] Based on the above principle, people have proposed a solution for a stereoscopic video shooting device: use two cameras at a certa...

AI Technical Summary

Problems solved by technology

The distance between two parallel cameras (that is, the baseline length) is more than 1 times the distance between the pupils of the human eyes (65mm). Although some baseline lengths can be adjusted, they cannot be adjusted in real time during the shooting process.

Although the up and down type can be adjusted to 65mm, its structure is complex and bulky, and it cannot be adjusted in real time.

[0005] The shooting angles of these two traditional stereoscopic video shooting devices are limited, making it difficult to shoot some close-up scenes and special stereoscopic effects

At the same time, these traditional devices cannot be applied to existing rocker arms and tripods in actual use, and are all experimental devices in nature
