Solution Overview
Problem
Existing user interfaces fail to effectively display and manage images with a wide field of view, particularly in applications like parking surface management, where precise control over image orientation and lighting is necessary.
Innovation Solution
A server-based method and system that includes user interfaces for correcting captured images with a wide field of view, allowing users to input rotational information and control points to adjust image orientation, zoom, and lighting settings, enabling dynamic display and management of parking surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a fisheye camera captures images with a wide field of view using a wide-angle lens, then the field of view is improved, but the image distortion increases
Solution Approach 1:
The patent divides the wide-field-of-view image into multiple regions with different distortion characteristics. It segments the image into a central region and peripheral regions, applying different correction parameters to each segment. This allows the central area to maintain higher precision while the peripheral areas accommodate the inherent distortion of wide-angle capture.
Solution Approach 2:
The patent applies local quality correction by assigning different correction strengths and parameters to different regions of the image. The central region receives stronger correction to maintain straight lines and geometric accuracy, while peripheral regions use milder correction to preserve the wide field of view advantage. This localized approach resolves the contradiction between overall distortion reduction and maintaining wide coverage.
2Ease of operation
If the user interface displays control points and segments for image correction, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic interaction where control points and segments automatically adjust based on user input. When a user interacts with one control point, the system dynamically updates the positions and orientations of other control points and segments, providing real-time feedback. This dynamic behavior simplifies operation by automatically coordinating multiple parameters rather than requiring manual adjustment of each element independently.
Solution Approach 2:
The patent incorporates visual feedback mechanisms where the user interface immediately responds to user actions. When users move control points or adjust segments, the system provides real-time visual feedback showing the expected image correction results. This feedback loop simplifies operation by allowing users to intuitively adjust parameters without needing to understand the underlying complex correction algorithms.

AI summary
An operating method for a server includes: displaying, on a screen of a user terminal, a first user interface including a first image obtained by correcting a captured image; displaying, on the screen of the user terminal, a second user interface including a first control point, a second control point, and a segment connecting the first control point to the second control point; obtaining a first user input from the first control point or the second control point; and in response to the first user input, displaying, through the first user interface, a second image obtained by correcting the captured image based on rotational information determined by the first control point, the second control point and the segment, and a center position of the first image.
