Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual lens 3D cameras face challenges in capturing high-quality 3D images at both long and short distances due to limitations in adjusting convergence angles and image overlap, resulting in reduced resolution and difficulty in maintaining image quality.
Innovation Solution
A distance adaptive 3D camera system with a guide axis and driving unit allows the first and second camera module units to move along this axis, controlled by a distance measuring unit and controller, to adjust their distance relative to the object, ensuring optimal image overlap and resolution across varying distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the dual lens 3D camera uses a fixed distance between camera modules, then the structure is simple and easy to manufacture, but the image overlap and resolution deteriorate when photographing objects at varying distances
Solution Approach 1:
The patent applies the dynamics principle by making the distance between camera modules adjustable rather than fixed. The first and second camera modules can move along the guide axis to change their separation distance, allowing the system to adapt to different object distances and maintain optimal image overlap and resolution across various photographing conditions.
Solution Approach 2:
The patent implements parameter changes by varying the distance parameter between camera modules based on the distance to the photographed object. When the object is far away, the camera modules are positioned farther apart; when the object is close, the modules are positioned closer together. This dynamic parameter adjustment optimizes the convergence angle and image overlap for different photographing scenarios.
2Adaptability or versatility
If the camera modules are positioned far apart, then the convergence angle is wide for long distance photographing, but the image overlap becomes insufficient for short distance photographing
Solution Approach 1:
The system dynamically adjusts the camera module positions based on the photographing distance. For long distance photographing, the modules are positioned far apart to achieve wide convergence angle; for short distance photographing, the modules are positioned close together to maintain sufficient image overlap. This dynamic positioning enables the system to adapt to various photographing scenarios while maintaining image quality.
Solution Approach 2:
The patent changes the distance parameter between camera modules according to the object distance. By adjusting this parameter, the system optimizes both convergence angle and image overlap for different photographing conditions, achieving versatile performance across both long and short distance ranges.
3Manufacturing precision
If the camera modules are positioned close together, then the image overlap is sufficient for short distance photographing, but the convergence angle becomes too narrow for long distance photographing
Solution Approach 1:
The patent applies dynamics by enabling the camera modules to move between close and far positions along the guide axis. When photographing close objects, the modules are positioned close together to achieve sufficient image overlap and resolution. When photographing distant objects, the modules are positioned far apart to achieve adequate convergence angle, thus adapting to different photographing scenarios.
Solution Approach 2:
The system dynamically changes the distance parameter between camera modules based on the photographing distance. This parameter adjustment allows the system to optimize image overlap for close objects and convergence angle for distant objects, achieving versatile performance across different distance ranges.
4Ease of operation
If a single lens 3D image photographing method is used, then synchronization between heads and zoom lenses is easy, but picture quality deteriorates at the border between left and right 3D images due to bi-prism adapter
Solution Approach 1:
The patent divides the imaging system into separate first and second camera modules that independently capture left and right images. This segmentation eliminates the need for a bi-prism adapter and allows each camera module to operate independently, avoiding the picture quality degradation that occurs at the border region in single-lens systems.
Solution Approach 2:
The patent extracts the problematic bi-prism adapter component from the system by using separate camera modules instead. This extraction removes the source of picture quality deterioration while maintaining the synchronization advantage through independent operation of each camera module.
