Panorama Creation for Small Subjects Using Fixed Camera Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for creating panoramic images struggle when the subject is smaller than the camera's view angle, as they are designed for larger subjects and require continuous image capture, making it difficult to apply these methods to smaller targets.
Innovation Solution
A method that involves photographing multiple images of a subject from different angles with a fixed camera, determining a reference region, extracting target regions, detecting common portions, and combining these regions to create a panoramic image, allowing for the creation of panoramic images from subjects smaller than the camera's view angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional panoramic image creation methods are used for subjects larger than camera view angle, then the panoramic image can be created by continuously photographing and synthesizing images, but the method cannot be applied to subjects smaller than camera view angle
Solution Approach 1:
Instead of moving the camera to photograph different portions of a large subject (conventional approach), the patent inverts the approach by keeping the camera fixed and moving the subject through the camera's view angle. This allows the same panoramic synthesis methodology to be applied to both large subjects (greater than view angle) and small subjects (smaller than view angle), thereby improving adaptability while maintaining reliability
Solution Approach 2:
The patent creates a universal panorama creation method that can handle both traditional large subjects and small subjects by changing which element moves (camera vs. subject). The core synthesis algorithm remains the same, making the system multi-functional and adaptable to different subject sizes without requiring separate methodologies
2Adaptability or versatility
If the camera is fixed and the subject is moved to create panoramic images of small subjects, then panoramic images can be created from subjects smaller than view angle, but the subject must be moved precisely through specific angles
Solution Approach 1:
The system automatically detects same portions between adjacent target regions and performs panoramic synthesis without requiring manual angle measurement or precise positioning by the operator. The camera remains fixed and the subject is simply moved through the view angle, while the system handles the complex tasks of region extraction, similarity detection, and image synthesis, thereby maintaining ease of operation while achieving adaptability to small subjects
3Manufacturing precision
If multiple images are extracted and synthesized to create a panorama, then a cohesive panoramic image capturing multiple sides of the subject is produced, but the process requires determining reference regions, extracting target regions, and detecting same portions
Solution Approach 1:
The patent performs preliminary actions by automatically determining reference regions and extracting target regions before the panoramic synthesis process. By pre-processing the images to identify and extract the relevant portions, the system simplifies the subsequent synthesis step while ensuring high accuracy. The reference region determination and target region extraction are performed in advance, organizing the complex processing into manageable sequential steps that improve overall synthesis accuracy

AI summary
A method is provided for creating a panorama. The method includes photographing a plurality of images having same backgrounds and different forms of a subject, determining a size and a position of a reference region for creating a panorama using the images, extracting a target region within the reference region from each of the images, detecting same portions in adjacent target regions, and creating a panorama by combining the adjacent target regions on the basis of the same portions.
