Image Capture Parameter Decision for Panoramic Depth of Field
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional panoramic image capturing systems face challenges in obtaining high-resolution images of large objects due to strong tilt angles, which result in significant differences in distance between near and far parts of the image-capturing target, making it difficult to achieve satisfactory focusing and resolution.
Innovation Solution
An information processing apparatus that acquires image-capturing environment information and image quality conditions, decides image-capturing parameters to fit the depth of field, and presents the optimal image-capturing range to the user, ensuring high-resolution image capture by adjusting focal distance and aperture settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If panoramic image capturing is performed with large rotation angle for huge structures, then the entire image-capturing range can be covered, but strong tilt is captured making it difficult to obtain high-resolution image
Solution Approach 1:
The system performs preliminary calculation of the depth of field range based on the rotation angle and imaging parameters before actual image capturing. This allows the user to know in advance whether the entire object can be captured in focus, and if not, to adjust the rotation angle or other parameters accordingly, avoiding wasted capturing attempts.
Solution Approach 2:
The system provides feedback to the user by displaying the calculated depth of field range and indicating whether the entire object plane can be captured in focus. This feedback loop allows the user to adjust parameters and re-capture if necessary, ensuring high-resolution images are obtained.
2Adaptability or versatility
If there is strong tilt with respect to image-capturing target, then large rotation angle is required, but the difference between near part and far part in terms of distance is large making it difficult to obtain high-resolution image
Solution Approach 1:
The system calculates the depth of field range in advance based on the rotation angle and imaging parameters, allowing the user to determine the appropriate rotation angle that will achieve the desired measurement precision for the entire object.
Solution Approach 2:
The system allows adjustment of imaging parameters such as focal length and aperture to optimize the depth of field range, enabling the user to achieve both large rotation angle coverage and sufficient measurement precision by changing these parameters.
3Extent of automation
If conventional panoramic image capturing is used, then automatic pan and tilt driving can be performed, but troublesome work is involved such as repeating image capturing while trying parameters
Solution Approach 1:
The system performs preliminary calculation of the depth of field range and provides feedback on whether the entire object can be captured in focus before actual image capturing begins. This prevents wasted time on capturing attempts that would fail to achieve the desired result.
Solution Approach 2:
The system provides real-time feedback to the user about the depth of field range and captures quality, allowing immediate parameter adjustment if necessary. This feedback mechanism eliminates the need for repeated trial-and-error capturing cycles.
