Monitoring Device Fisheye to Rectangular Image Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems face difficulties in distinguishing relationships between monitoring cameras and images, making it complicated to operate individual images effectively when combining multiple images into a single display.
Innovation Solution
A monitoring device with a receiver for fisheye images, an image transformer to convert fisheye images into rectangular or PTZ views, and a controller to provide a user interface with image windows that allow switching between different image formats, enabling easy operation and visualization of monitoring areas.

Engineering Contradiction Analysis
1Loss of information
If multiple fisheye images are combined into a single display, then the overall monitoring situation can be easily grasped, but it becomes difficult to distinguish relationships between monitoring cameras and images, and complicated to operate individual images
Solution Approach 1:
The display screen is divided into multiple image windows, with each window showing a rectangular image from a specific monitoring camera. This segmentation allows operators to view the overall situation across multiple windows while maintaining the ability to individually operate and distinguish each camera's image through separate window controls and visual indicators.
2Stability of the object's composition
If fisheye images are transformed into rectangular images, then the continuity of image paths can be improved, but the field of view and monitoring coverage may be reduced
Solution Approach 1:
The system transforms fisheye images from a spherical projection into rectangular images, changing the dimensional representation while maintaining the essential spatial relationships. This transformation improves image path continuity for tracking moving objects, and the system compensates for the reduced field of view by strategically positioning multiple cameras and using image stitching techniques to reconstruct the broader monitoring area across multiple rectangular images.

AI summary
A monitoring device includes a receiver, configured to receive a fisheye image of a bird's eye viewpoint captured by a plurality of monitoring cameras, an image transformer, configured to transform the fisheye image into a rectangular image of the bird's eye viewpoint or a different viewpoint image which is an image of a viewpoint different from the bird's eye viewpoint, and a controller, configured to provide a user interface which arranges a plurality of image windows respectively corresponding to the plurality of monitoring cameras, displays the rectangular image in the image windows, and switches a displayed image to the different viewpoint image for each image window.
