Innovation Solution
An image processing apparatus that includes an inputting section for continuous images, an extracting section for characteristic points, a tracking section for tracking points, an embedding section for embedding tracking data into each image, and an outputting section for embedding tracking data into the images, allowing for easy management and selection of suitable images for orientation processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If characteristic points are extracted and tracked from moving image data to perform photogrammetry, then orientation processing can be automated, but management of various tracking data becomes difficult when dealing with large numbers of frame images
Solution Approach 1:
The patent combines tracking data with image data by embedding tracking data into image files. This merging eliminates the need for separate data management systems for tracking information, reducing complexity while maintaining automation. The embedding section integrates tracking data (point coordinates, evaluation values, generation information) directly into the image structure, allowing unified management of both image and tracking data.
Solution Approach 2:
The image file structure is designed to serve multiple functions: storing image data, embedding tracking data, and providing identification information for orientation processing. This multi-functional approach allows the same data structure to handle both visual information and processing metadata, simplifying the overall system architecture while maintaining automated orientation capabilities.
2Reliability
If tracking data is managed separately from image data, then data integrity can be maintained, but data transfer efficiency decreases and requires more components
Solution Approach 1:
By embedding tracking data within image files, the patent creates a unified data structure that maintains data integrity through atomic file units while improving transfer efficiency. The combined structure ensures that image and tracking data are always synchronized and transferred together, eliminating the need for separate data management components and reducing transfer overhead.
3Manufacturing precision
If all continuous images are processed for orientation, then complete coverage is achieved, but processing time increases and not all images may be suitable
Solution Approach 1:
The patent performs preliminary evaluation of tracking data during the point tracking phase, calculating evaluation values that indicate image suitability for orientation processing. This preliminary assessment allows the system to identify suitable images before orientation processing begins, avoiding wasted computation on inappropriate images and reducing overall processing time while maintaining orientation accuracy.
Solution Approach 2:
Instead of processing all continuous images, the patent selectively processes only those images that meet specific criteria (sufficient tracking points, good evaluation values, appropriate generation relationships). This partial processing approach reduces computation time while ensuring that only quality images contribute to orientation accuracy, achieving the optimal balance between speed and precision.
