Dual-Camera Size Measurement for Real-Time Product Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing real-time product inspection methods struggle to provide accurate and precise size information while improving production efficiency, as they often rely on single-camera imaging that can only measure rough outlines.
Innovation Solution
A measurement method involving dual-camera imaging, one on the non-backlight side and one on the backlight side of the target object, to capture complementary information for precise size measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single camera is used for real-time inspection, then production efficiency is improved, but measurement precision deteriorates
Solution Approach 1:
The patent combines images from two cameras positioned at different locations (front and side views) to create a composite measurement system. This merging of multiple image sources enables both real-time inspection capability and high measurement precision by capturing complementary information about the target object's dimensions and features.
Solution Approach 2:
The patent transitions from single-camera 2D imaging to multi-camera 3D imaging by positioning cameras at different spatial locations. The front view camera and side view camera capture images from different dimensions, enabling comprehensive size measurement that maintains both speed and precision.
2Measurement precision
If separate inspection apparatus is used, then measurement accuracy is maintained, but production efficiency deteriorates
Solution Approach 1:
The patent merges the inspection function into the production line by integrating dual-camera imaging directly into the manufacturing process. This combination eliminates the need for separate post-production inspection apparatus, maintaining measurement accuracy while improving production efficiency through real-time detection.
Solution Approach 2:
The inspection system operates continuously during the production process rather than as a separate batch operation. The dual-camera system captures images in real-time as products move through the production line, enabling continuous measurement that maintains accuracy without interrupting production flow.
3Productivity
If rough outline measurement is used, then production efficiency is improved, but measurement precision deteriorates
Solution Approach 1:
The patent segments the measurement task into two complementary views: front view measurement and side view measurement. Each camera captures specific dimensional information, and the combination of these segmented measurements provides both rapid inspection capability and detailed fine size information about the target object.
Solution Approach 2:
The patent merges measurement data from multiple viewing angles to achieve comprehensive precision. By combining the front view image data with side view image data, the system retrieves detailed fine size information that neither single view could provide alone, while maintaining high inspection speed.
