Image Acquisition System with Relative Position Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image acquisition systems require precise alignment and large-scale devices for accurate positioning of the image acquisition device relative to the display device, which is cumbersome and unnecessary for proper illumination and image acquisition.
Innovation Solution
An image acquisition system with a display device having a display surface and an image acquisition device disposed face-down above it, where the display device includes a relative-position calculation unit to determine the relative position between the devices and a display control unit to adjust content display based on this position, allowing for rough alignment and accurate image acquisition without the need for high-precision positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If precise alignment and large-scale devices are used for positioning, then image acquisition accuracy is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a computational approach. The display device captures an image of the image acquisition device, and a processor calculates the relative position based on image analysis. This substitutes mechanical alignment mechanisms with optical-mechanical-image processing integration, achieving high-accuracy positioning without complex mechanical structures.
2Measurement precision
If large-scale devices are used for positioning, then positioning accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-alignment through automated image capture and processing. The display device automatically captures the image acquisition device, the processor calculates relative position, and the system adjusts illumination and display regions without manual intervention. This self-service mechanism eliminates the need for operators to perform complex alignment operations while maintaining high positioning accuracy.
3Ease of operation
If rough alignment is allowed, then ease of operation is improved, but image acquisition accuracy deteriorates
Solution Approach 1:
The system uses feedback from captured images to achieve accurate positioning. The display device captures the image acquisition device, the processor analyzes the image to calculate relative position, and this information feeds back to adjust illumination and display regions. This feedback loop enables the system to compensate for rough initial alignment and achieve high-accuracy image acquisition automatically.
