Pseudo-Stereoscopic Image Generation for Mirror Welding Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Training in environments like mirror welding can be challenging due to the complexity and difficulty of visualizing tasks, especially in tight spaces where using mirrors is necessary, requiring advanced training and skill, and existing methods do not effectively simplify the process.
Innovation Solution
A method and system that converts a single video source image into a pseudo-stereoscopic image by duplicating, cropping, and offsetting it, allowing users to perceive depth through a stereoscopic display, which can be integrated into a welding helmet with a Bluetooth module and virtual reality lenses, enhancing visualization and reducing the need for mirror imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mirrors are used for visualization in tight spaces, then the user can see the work area, but the image is mirrored requiring advanced training and skill to interpret
Solution Approach 1:
The patent inverts the conventional mirrored image approach by using stereoscopic imaging that presents a non-mirrored, natural view of the work area. Instead of showing a reflected image that requires mirror-reading skills, the system captures and displays the actual scene as seen by the camera, eliminating the need for workers to relearn spatial orientation while maintaining visualization capability in tight spaces
2Measurement precision
If stereoscopic display is implemented, then depth perception is improved, but the system complexity increases
Solution Approach 1:
The patent creates a stereoscopic copy of the visual scene by generating multiple slightly offset images from a single camera view, simulating the natural separation between human eyes. This copying approach provides authentic depth perception without requiring complex multi-camera rig setups, as the stereoscopic effect is achieved through image processing and computational generation of the duplicate视角
Solution Approach 2:
The patent introduces a stereoscopic display system as an intermediary between the worker and the actual work area. This intermediary processes and presents the visual information in a depth-enhanced format, allowing the worker to perceive spatial relationships more accurately without directly observing the physical environment, thereby reducing the need for complex physical imaging setups
3Productivity
If mirror welding training is provided, then workers can perform mirror welding, but the training process is lengthy and complex
Solution Approach 1:
The patent fundamentally changes the training approach by inverting the image presentation from mirrored to non-mirrored. Instead of training workers to interpret mirrored images, the system displays the work area as it naturally appears, allowing workers to immediately understand spatial relationships without lengthy training on mirror interpretation, while still enabling mirror welding capability
