Multi-Camera Array for Wide Field of View Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for capturing wide fields of view using stereoscopic cameras face interference issues and limitations in angular range, particularly with wide-angle cameras, where adjacent cameras can interfere with each other, restricting the practical field of view.
Innovation Solution
An array of monoscopic and stereoscopic detectors, including cameras and microphones, is employed to capture images and audio from ranges exceeding those of a single detector or stereoscopic pair, with adjustable image capture mechanisms to align and extend the field of view, using multiple cameras and microphones positioned to avoid interference and enhance coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wide angle cameras with 180 degree field of view are used, then the field of view coverage is improved, but adjacent cameras interfere with each other
Solution Approach 1:
The patent divides the wide field of view capture task into multiple segments by using multiple cameras with narrower fields of view (e.g., 45-60 degrees) arranged in an array. Each camera captures a specific angular segment, and the segments are later combined to form a complete panoramic or stereoscopic image, avoiding the interference problem of wide-angle cameras while maintaining comprehensive coverage.
Solution Approach 2:
The patent transitions from using a single wide-angle camera to a multi-camera array arranged in specific spatial dimensions. By distributing cameras across multiple positions and angles, the system achieves wide field of view coverage without the optical interference that occurs when multiple wide-angle cameras are placed adjacent to each other.
2Length of stationary object
If multiple cameras are arranged to extend field of view range, then the detection range is improved, but the device complexity increases
Solution Approach 1:
The patent designs a universal camera array system that can capture both monoscopic images and stereoscopic pairs using the same hardware configuration. The system can operate in different modes (monoscopic or stereoscopic) and can be applied to various applications such as panoramic imaging, 360-degree video, and depth mapping, reducing the need for separate specialized systems.
Solution Approach 2:
The patent uses identical or similar camera units repeated in an array configuration. Each camera in the array is a copy of the same standardized unit, which simplifies the overall system design, calibration, and maintenance. This modular approach reduces device complexity compared to using different types of cameras with varying specifications.
3Measurement precision
If stereoscopic pairs of cameras are used, then depth perception capability is improved, but the field of view is limited compared to monoscopic arrays
Solution Approach 1:
The patent merges the advantages of both monoscopic and stereoscopic camera systems by combining multiple stereoscopic pairs in an array. Each pair provides depth perception for its specific angular segment, and the combination of all pairs extends the overall field of view while maintaining depth perception capability across the entire panoramic view.

AI summary
An apparatus is provided for capturing images including a base, and image capture adjustment mechanism, a first camera, and a second camera. The base is constructed and arranged to support an alignable array of cameras. The image capture adjustment mechanism is disposed relative to the base for adjusting an image capture line of sight for a camera relative to the base. The first camera is carried by the base, operably coupled with the image capture adjustment mechanism, and has an image capture device. The first camera has a line of sight defining a first field of view adjustable with the image capture adjustment mechanism relative to the base. The second camera is carried by the base and has an image capture device. The second camera has a line of sight defining a second field of view extending beyond a range of the field of view for the first camera in order to produce a field of view that is greater than the field of view provided by the first camera. A method is also provided.
