3D Camera Module Convergence Control via Multi-Axis Lens Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D stereoscopic cameras are inadequate for shooting relatively short-distanced 3D stereoscopic images due to limited horizontal actuator movement, which restricts convergence angle adjustment.
Innovation Solution
A 3D stereoscopic camera module with multiple coils and magnets arranged in a rectangular parallelepiped configuration, allowing vertical and horizontal movement and tilting of camera lenses to control convergence angles effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If horizontal actuator movement is used for convergence angle control, then mid/far distanced 3D stereoscopic images can be captured, but relatively short distanced 3D stereoscopic images cannot be captured effectively
Solution Approach 1:
The invention transitions from single-direction (horizontal) actuator movement to multi-directional movement by adding vertical movement capability. The lens assembly can now move horizontally and vertically, and also tilt, providing two-dimensional positional adjustment plus angular adjustment. This dimensional expansion enables effective convergence angle control for both far and short distances.
Solution Approach 2:
The invention implements dynamic adjustment capability where the lens assembly can be actively positioned and tilted based on shooting distance requirements. The convergence angle is no longer fixed or limited to horizontal adjustment only, but can be dynamically adjusted in multiple directions to adapt to different shooting scenarios, particularly enabling short-distance 3D capture.
2Device complexity
If fixed image sensors with horizontal actuators are used, then结构简单性 is maintained, but convergence angle adjustment is limited
Solution Approach 1:
The invention merges multiple functions into a single integrated lens assembly that can be both positioned (horizontal and vertical movement) and tilted. Instead of separate mechanisms for position control and angle control, the lens assembly performs both functions, simplifying the overall structure while enhancing operational flexibility for convergence angle adjustment.
Solution Approach 2:
The lens assembly serves multiple functions: it acts as both the optical element and the adjustable component for convergence control. By making the lens assembly itself movable and tiltable, the design eliminates the need for separate actuators and mechanisms, achieving multi-functionality that improves both structural simplicity and operational flexibility.
