Multi-DOF Camera Adjustment for Curved Surface Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera structures are limited in their ability to adjust to the precise angles and orientations needed for high-precision optical measurement of smooth curved surfaces, leading to reduced imaging quality and manual detection methods, especially for surfaces with specular reflection, where the angle between the camera and the surface significantly affects imaging quality.
Innovation Solution
A multi-degree-of-freedom attitude adjustment camera apparatus with a camera adjusting module comprising an upper and lower chassis connected by bolts and motors, allowing for precise adjustment of the camera's position and orientation based on image feedback to ensure the CCD array is parallel to the measurement surface, and a control method that adjusts the camera's attitude to improve image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed camera structure or one-way adjustment is used, then the device complexity is reduced, but the imaging precision deteriorates due to inability to achieve proper parallel alignment with curved surfaces
Solution Approach 1:
The patent transforms the fixed camera structure into a dynamic adjustable system. The camera is mounted on a movable platform with multiple adjustment mechanisms including a tilting mechanism (with first and second adjustment knobs) and a positioning mechanism (with third and fourth adjustment knobs), allowing real-time modification of the camera's attitude and orientation to achieve optimal imaging conditions for curved surfaces.
Solution Approach 2:
The adjustment system is divided into independent functional modules: a tilting mechanism for adjusting the camera's tilt angle, a positioning mechanism for lateral and longitudinal positioning, and a height adjustment mechanism. Each module can be adjusted independently through dedicated knobs and mechanisms, enabling precise control over the camera's spatial orientation and position.
2Productivity
If manual detection methods are used for smooth curved surfaces, then the ease of operation is improved, but the productivity deteriorates due to inability to perform automatic detection
Solution Approach 1:
The system incorporates image quality feedback mechanisms where the camera captures images of the curved surface and the system evaluates whether the imaging quality meets predefined standards. Based on this feedback, the system automatically adjusts the camera's attitude and positioning through the adjustment mechanisms until optimal imaging conditions are achieved, enabling automatic detection without manual intervention.
Solution Approach 2:
The camera system performs self-adjustment through automated control of the tilting and positioning mechanisms. The system autonomously modifies its own orientation and position based on detected image quality metrics, eliminating the need for manual operation while maintaining detection efficiency and simplicity.
3Measurement precision
If the camera angle is not properly adjusted relative to the curved surface, then the ease of operation is improved, but the imaging quality deteriorates due to specular reflection effects
Solution Approach 1:
The camera mounting system incorporates dynamic adjustment capabilities through tilting mechanisms with adjustable angles. The first and second adjustment knobs enable real-time modification of the camera's tilt angle relative to the curved surface, allowing the system to adapt to different surface geometries and lighting conditions to minimize specular reflection and optimize imaging quality.
