Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stereoscopic cameras face challenges in adjusting binocular disparity, convergence angle, tilting, rolling, and camera position due to complex and costly adjustment modules, and limited selection of first image formation lenses, making them difficult to use and manufacture efficiently.
Innovation Solution
A monocular stereoscopic camera design that incorporates a first image formation lens assembly, a half mirror, and third image formation lens assemblies arranged perpendicularly, with a second image formation lens assembly that can be used to enlarge images and correct chromatic aberration, allowing for a wide range of lens selection and simplified adjustment of camera parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex adjustment module is used to adjust binocular disparity and convergence angle, then adjustment precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the adjustment function from a complex dedicated adjustment module and integrates it into the camera rig structure itself. The adjustment means are distributed across the rig components rather than concentrated in a separate complex module, simplifying the overall device while maintaining adjustment capability.
Solution Approach 2:
The camera rig structure serves multiple functions: it provides mechanical support for the cameras, enables adjustment of binocular disparity through positional adjustments, and allows convergence angle adjustment through rotational movements. This multi-functionality eliminates the need for separate complex adjustment modules.
2Adaptability or versatility
If a wide variety of first image formation lenses are selected, then adaptability is improved, but device complexity increases
Solution Approach 1:
The camera rig is designed with a universal mounting structure that can accommodate various types of first image formation lenses (macro lenses, telephoto lenses, standard lenses) without requiring different rig configurations. This universal design enables lens selection flexibility while maintaining simple device structure.
Solution Approach 2:
The rig allows dynamic adjustment of lens positions and orientations to optimize performance for different lens types and shooting scenarios. This adjustability provides adaptability for various lenses without requiring complex dedicated structures for each lens type.
3Ease of manufacture
If the camera rig structure is simplified, then ease of manufacture is improved, but adjustment capability may be compromised
Solution Approach 1:
The adjustment mechanism is segmented into independent adjustment means for different parameters (binocular disparity adjustment through positional changes, convergence angle adjustment through rotational changes). This segmentation allows simple manufacturing of individual components while maintaining comprehensive adjustment capability through their coordinated operation.
4Length of moving object
If the entire length of the camera is reduced, then volume is improved, but lens selection is limited
Solution Approach 1:
The patent utilizes perpendicular arrangement of cameras and optical paths to reduce the overall length of the camera rig. By arranging components in three-dimensional space rather than a single linear dimension, the design accommodates various lens types within a compact form factor.

AI summary
A monocular stereoscopic camera according to the present invention uses a macro lens capable of performing proximity expansion shooting as a third image formation lens assembly or a telephoto lens having, in combination with a second image formation lens assembly, the characteristics of a macro lens. Thus, the monocular stereoscopic camera has an advantage in that the camera can use various first image formation lens assemblies, reduce a vignetting phenomenon, reduce the entire length thereof, remove n adjustment parameter, which is repetitive and replaceable, from among parameters requiring adjustment of an optical axis, and distinguish a parameter to be adjusted during shooting and an adjustment parameter which may be fixed during shooting once after adjustment, from each other. Thus, the camera can be easily and simply manipulated and operated and has a simple structure.
