3D Image Generation Using Overlapping Camera Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional monitoring systems using a single camera can only monitor a specific area and lack the capability to generate three-dimensional images, resulting in blind spots and limited distance estimation, as they rely on mechanical drivers for pan, tilt, and zoom operations, preventing omnidirectional monitoring without mechanical drivers.
Innovation Solution
A system comprising multiple monitoring cameras with overlapping angles of view, a controller that crops and combines overlapping images to generate 3D images, allowing for electrical control and multi-access monitoring, enabling the generation of 3D panorama images and space information extraction without mechanical driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one monitoring camera is used to reduce device complexity, then device complexity is reduced, but monitoring coverage and 3D image generation capability deteriorate
Solution Approach 1:
The monitoring area is segmented into multiple zones, each captured by a separate camera positioned at different angles. Each camera captures a specific sector of the overall area, and the controller integrates these segmented views to form a complete monitoring coverage and generate 3D images of the entire area.
2Adaptability or versatility
If mechanical drivers are used for pan, tilt, and zoom operations to improve monitoring flexibility, then monitoring flexibility is improved, but device complexity and reliability deteriorate
Solution Approach 1:
The patent replaces mechanical pan, tilt, and zoom drivers with a multi-camera array system. Instead of mechanically moving a single camera to change viewing angles, multiple fixed cameras are positioned at different orientations, and the controller electronically selects and combines their views to achieve the same monitoring flexibility without mechanical complexity.
3Measurement precision
If multiple monitoring cameras are used to generate 3D images and eliminate blind spots, then monitoring coverage and measurement precision are improved, but device complexity increases
Solution Approach 1:
The patent transitions from 2D planar monitoring to 3D spatial monitoring by positioning multiple cameras at different angular positions around the monitoring area. This dimensional change enables the system to capture depth information and generate true 3D images, eliminating blind spots and improving distance estimation accuracy through multi-angle viewpoint integration.

AI summary
A monitoring system for generating a three-dimensional (3D) image, the system including: a plurality of monitoring cameras which are arranged to capture respective images of an area such that a portion of an angle of view of one monitoring camera overlaps a portion of an angle of view of another monitoring camera; and a controller which crops a plurality of overlapped images, each of which is an image of the overlapped portion, from among the respective images captured by the plurality of monitoring cameras, and generates a 3D image by adding the overlapped images.
