Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CCTV control systems face challenges with increased network cameras leading to high image data transmission loads, resulting in degraded image quality and difficulty in monitoring multiple camera feeds effectively, as they typically display images in a 2D lattice format, making it hard to recognize camera locations and spatial correlations.
Innovation Solution
An intelligent control system utilizing 3D rendering technology to display images from multiple network cameras in a 3D modeling space on a single screen, allowing users to adjust image resolution based on their viewpoint, and optimizing rendering rates by integrating and compressing image streams, thereby reducing network load and enhancing monitoring efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of network cameras is increased to improve surveillance coverage, then the surveillance area coverage is improved, but the network transmission load increases and image quality degrades
Solution Approach 1:
The patent transitions from traditional 2D lattice display to 3D spherical projection display, organizing multiple camera feeds in a three-dimensional space. This dimensional change allows efficient presentation of numerous camera views without increasing network load, as the system selectively processes and transmits only necessary image data at appropriate resolutions.
2Area of stationary object
If the number of network cameras is increased to improve surveillance coverage, then the surveillance area coverage is improved, but the image quality on display degrades
Solution Approach 1:
The system applies different image qualities and resolutions to different regions and cameras based on their importance and viewing requirements. The 3D spherical projection allows operators to focus on specific areas of interest with higher resolution while maintaining lower resolution for less critical areas, optimizing overall image quality without requiring uniform high resolution across all feeds.
3Manufacturing precision
If multiple image streams are processed and displayed separately to maintain image quality, then the image quality is maintained, but the network load and processing overhead increase
Solution Approach 1:
The patent merges multiple camera image streams into a unified 3D spherical projection display. Instead of processing and transmitting separate image streams for each camera, the system integrates them into a single coherent 3D representation, reducing redundant data transmission and processing overhead while maintaining the ability to display high-quality images on demand.
4Device complexity
If traditional 2D lattice display is used to show multiple camera feeds, then the system complexity is low, but the ease of operation and understanding of camera locations is poor
Solution Approach 1:
The system employs 3D spherical projection to represent camera locations and fields of view, providing intuitive spatial awareness. Operators can visually understand camera positions and coverage areas in three-dimensional space, making it easier to identify locations and monitor specific areas compared to traditional 2D lattice arrangements that require mental mapping.
