Composite Facial Image Generation from Multiple Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio/video recording and communication devices, such as doorbells, often capture only partial facial images, which are insufficient for positive identification of individuals, hindering crime prevention and public safety.
Innovation Solution
The system generates composite facial images by analyzing and combining partial facial images from multiple cameras, enabling the creation of a more complete and recognizable image of individuals, facilitating identification and apprehension of criminal perpetrators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple cameras are deployed to capture facial images from different angles, then the completeness of facial image data is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent combines multiple partial facial images from different cameras into a single composite facial image. The system merges the image data, aligns facial features, and generates a unified complete facial image that contains all visible facial portions from the multiple source images, thereby resolving the information loss problem while managing system complexity through integrated processing.
Solution Approach 2:
The patent introduces a server as an intermediary component that receives image data from multiple cameras, performs the complex task of generating composite facial images, and returns the results to client devices. This intermediary architecture separates the complexity of image processing from the camera devices themselves, allowing the cameras to remain simple while the server handles the sophisticated composite image generation.
2Reliability
If partial facial images are used alone, then the device complexity is reduced, but the identification accuracy and reliability are insufficient
Solution Approach 1:
The patent merges multiple partial facial images into a single composite image that provides complete facial information for reliable identification. By combining the visual data from multiple angles and sources, the system achieves high identification reliability without requiring each individual camera to be overly complex.
Solution Approach 2:
The patent adds the dimension of multiple viewing angles by capturing facial images from different cameras positioned at various locations. This multi-dimensional approach to image collection provides comprehensive facial coverage that significantly improves identification reliability, transforming the problem from 2D single-angle imaging to 3D multi-angle composite imaging.
Data Source
AI summary
Some embodiments provide methods for providing images of a person generated by two or more A/V recording and communication devices to one or more users, via a user's client device. For example, first image data may be received from a first A/V recording and communication device at a first location and second image data may be received from a second A/V recording and communication device at a second location. The first image data and the second image data may be analyzed to determine a person depicted in the first image data and a person depicted in the second image data is the same person. In response, a user alert may be generated including data representative of a first facial image of the person and a second facial image of the person. The user alert may then be transmitted to a user's client device.
