Composite Video Image Stabilization for Vibrating Camera Arrays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for generating composite video images from multiple cameras are sensitive to camera maladjustments, making them unsuitable for unstable or hard-to-access locations, such as vibrating masts or rocking buoys, which require constant maintenance to prevent mosaic disruptions.
Innovation Solution
A system comprising video cameras configured to capture overlapping images on a three-dimensional surface, with control means that monitor and adjust the guard zones of overlapping images to maintain stability, allowing for slight maladjustments without affecting the composite image, and includes navigation and alarm features for maintaining image integrity and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras are placed in hard-to-access areas prone to vibrations and blows, then video surveillance coverage is improved, but camera stability and image quality deteriorate
Solution Approach 1:
The system continuously monitors the guard zones between adjacent video images and uses this feedback to detect camera maladjustments. When a maladjustment is detected in the guard zone overlap, the system automatically corrects the camera position or adjusts the image transformation to restore proper overlap, ensuring stable composite image generation despite vibrations and blows in hard-to-access locations
Solution Approach 2:
The system performs self-correction by automatically detecting guard zone maladjustments and adjusting camera positions or image transformations without human intervention. This allows cameras in unstable, hard-to-access areas to maintain proper function without requiring frequent manual maintenance or repositioning by technicians
2Manufacturing precision
If strict camera calibration is required for mosaic image generation, then image quality is improved, but system complexity and maintenance requirements increase
Solution Approach 1:
The system performs preliminary monitoring of guard zones to detect maladjustments before they significantly degrade image quality. By continuously checking the overlap between adjacent images and correcting issues proactively, the system maintains high image quality without requiring constant manual calibration or complex adjustment procedures
Solution Approach 2:
The system dynamically adjusts transformation parameters of the video images based on detected guard zone maladjustments. By changing the transformation parameters to compensate for camera position shifts, the system maintains proper image alignment and quality without requiring physical camera recalibration, thereby reducing system complexity

AI summary
The present invention relates to a system and method for obtaining a composite video image which allows obtaining a stable composite video image from one or several groups of video cameras located in hard-to-access areas that are prone to receiving vibrations and minor blows to perform video surveillance functions, medical functions, etc. The system comprises a group of video cameras configured for focusing on and obtaining adjacent video images over a solid area that overlap in a guard zone; and control means configured for generating a composite video image for its placement on a virtual canvas which reproduces the surface focused on by the cameras, the video images overlapping at the their guard zone, the control means being programmed for monitoring said guard zones and correcting the position of the video images for maintaining the stability of the composite video image.
