Multi-Camera Object Detection for Incomplete Zoomed Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to accurately analyze images and identify objects when there is insufficient information, such as when images are taken with zoomed-in cameras, missing parts of the object, leading to incomplete object recognition.
Innovation Solution
The electronic device uses multiple cameras, one in zoom mode and one in normal mode, to obtain images, detect objects, and perform object recognition by correlating the images to accurately identify objects even when zoomed-in images are incomplete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera operates in zoom mode to capture images of objects, then the magnification and detail of the object is improved, but the completeness of the object information is lost because parts of the object are missed
Solution Approach 1:
The patent divides the imaging function into two segments: a first camera for capturing zoomed-in images and a second camera for capturing normal images. By segmenting the imaging task between two cameras with different focal lengths, the system can simultaneously obtain both detailed views and complete object information, resolving the contradiction between magnification precision and information completeness.
Solution Approach 2:
The processor acts as an intermediary that receives images from both cameras and performs object detection and recognition by analyzing both the zoomed-in first image and the complete second image. This intermediary processing enables the system to leverage the advantages of both imaging modes to achieve both detailed detection and complete object identification.
2Reliability
If multiple cameras are used to obtain both zoomed-in and normal images, then the object recognition accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent implements a multi-functional camera system where both the first and second cameras serve dual purposes: capturing images for object detection and providing reference information for the processor. The system uses the same hardware infrastructure for both imaging modes, allowing the cameras to perform multiple functions (detailed imaging and complete imaging) without requiring entirely separate systems, thus managing complexity while improving reliability.
