Surveillance System Adaptive Scrolling for Moving Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surveillance video systems face challenges with narrow fields of view, high data storage and processing demands due to high-resolution images, and limited bandwidth and computational resources in mobile applications, making it difficult to effectively monitor large areas and maintain visibility of moving targets without constant user input.
Innovation Solution
A surveillance video system that processes high-resolution surveillance image files into a video transport stream for a selectable region of interest, allowing adaptive scrolling to maintain a moving target visible on a display without constant user input, using transcoding and predictive path generation based on velocity and acceleration, and communicating with a server to manage bandwidth and storage efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If high-resolution WAPS images are used to expand surveillance coverage, then the field of view and surveillance coverage are improved, but the data storage space and processing requirements increase dramatically
Solution Approach 1:
The patent divides the large WAPS image into multiple smaller thumbnail images arranged in a grid layout. Each thumbnail represents a specific region of the original high-resolution image. This segmentation allows the system to display multiple views of different areas simultaneously without requiring the full high-resolution image data to be loaded and processed, thereby reducing memory consumption and improving rendering efficiency while maintaining broad surveillance coverage.
2Area of stationary object
If the entire WAPS image is displayed on a mobile device, then complete area coverage is achieved, but the limited screen size makes viewing problematic
Solution Approach 1:
The patent segments the large WAPS image into multiple thumbnail images that can be displayed in a grid format on the mobile device screen. This allows users to view multiple regions of interest simultaneously without needing to zoom or pan across a single large image, making the limited screen size more effective for monitoring multiple areas.
Solution Approach 2:
The patent transitions from displaying a single large 2D image to displaying multiple smaller 2D thumbnails arranged in a spatial grid. This dimensional reorganization allows the system to fit more information within the constrained screen real estate by utilizing the spatial arrangement of multiple smaller units rather than attempting to display one large unit.
3Reliability
If WAPS imagery is used in mobile applications, then comprehensive surveillance is achieved, but the large file size makes applications resource intensive
Solution Approach 1:
The patent divides the computationally intensive WAPS image processing into multiple smaller thumbnail generations. Instead of processing and displaying the entire high-resolution image, the system processes smaller regions independently to create thumbnails, significantly reducing the computational burden on mobile devices while maintaining the ability to monitor the complete surveillance area through the grid of thumbnails.
4Measurement precision
If high-resolution images are processed, then image quality is improved, but bandwidth requirements increase
Solution Approach 1:
The patent segments the high-resolution image data into multiple smaller thumbnail images for transmission. Instead of transmitting the entire large WAPS image over the network, the system transmits only the necessary thumbnail data to the mobile device, significantly reducing bandwidth consumption while maintaining sufficient image quality for surveillance purposes through the segmented view.

AI summary
A surveillance video system may include a first device configured to process successive surveillance image files of a common area into an image transport stream for a selectable region of interest within the common area. The surveillance video system also may include a second device remote from the first device and in communication with the first device. The second device may include a display and a processor cooperating therewith. The processor may be configured to scroll the selectable region of interest to maintain a selected moving target visible on the display.
