Complete Cylindrical Surface Inspection (70)
Problem: Provide real-time, 100% inspection of cylindrical nuclear fuel pellet surface using a single video camera
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement & Analysis System Applications
PNNL Solution:
- Developed method to provide uniform, all surface illumination
- Developed optical system with single video camera that captures simultaneous, full cylinder images
- Successfully deployed and demonstrated system operation
- Published project results
Capabilities Employed to Meet Client Needs: Illumination and imaging studies to establish practical requirements to detect targeted fuel pellet defects; practical illumination system development; multisegment, coherent fiber-optic bundle development to provide full cylinder surface imaging onto a single video camera; video imaging system with video recordkeeping; digital image processing to stitch six segmented images into a seamless single image; automated image processing to enhance targeted surface flaws; multiimage display and operator interface development; formal reporting of results; publication of findings in SPIE paper.
