A mechanical arm structure of a portable adaptive image 3D reconstruction instrument

Abstract

A mechanical arm structure of a portable self-adaptive image three-dimensional reconstruction instrument comprises a base, a first rotary shaft and a mechanical arm structure body connected with the base through the first rotary shaft. A mechanical arm rotary handle, a mechanical arm reduction gear set and a mechanical arm worm and gear structure are arranged on the base, and the mechanical arm rotary handle is connected with the first rotary shaft through the mechanical arm reduction gear set and the mechanical arm worm and gear structure in sequence. The mechanical arm structure body is mainly composed of a mechanical arm, a mechanical arm locking mechanism, a mechanical arm telescopic mechanism, a camera mounting mechanism and a camera mounting locking mechanism. An optical camera is fixedly arranged on the camera mounting mechanism, when the mechanical arm rotates to drive the camera mounting mechanism to swing along an arc path, the mechanical arm can be manually controlled to rotate along the arc path, the camera fixedly arranged on the mechanical arm is used for taking pictures at different angles along the arc path, and the shooting angle of the optical camera is wider.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a mechanical arm structure of a portable adaptive image three-dimensional reconstruction instrument. Background technique [0002] Generally, a camera manipulator that is manually controlled is to manually adjust the camera angle fixed at one end of the manipulator, and set a counterweight at the other end of the manipulator to balance the load at both ends of the manipulator. And do not utilize transmission mechanism to drive the setting of photographing mechanical arm. [0003] Generally, the automatic camera arm is driven by a servo motor instead of a worm and a worm wheel. [0004] Whether it is manual or automatic control of the camera arm, the general camera arm cannot adjust the shooting radius and the height of the center of rotation of the camera arm. [0005] With the size of the subject, it is necessary to adjust the shooting radius to obtain a better shooting effect. ...

AI Technical Summary

Problems solved by technology

[0004] Whether it is manual or automatic control of the camera arm, the general camera arm cannot adjust the shooting radius and the height of the center of rotation of the camera arm.

[0005] With the size of the subject, the radius of the camera must be adjusted to achieve better shooting results. The general camera equipment is fixed on a fixed arc track, and the radius of the camera cannot be adjusted.

It is very inconvenient to change the arc track when changing the subject

[0006] If there is no mechanism to adjust the height of the camera arm's rotation center, once the turntable is used for 3D stereo photography, the height of the turntable surface and the camera arm's rotation center may not be on the same level, resulting in the 3D stereo images captured.
