Automated Telerobotic Inspection Of Surfaces

Method of automated telerobotic inspection of surfaces undergoing development. Apparatus implementing method includes video camera that scans over surfaces to be inspected, in manner of mine detector. Images of surfaces compared with reference images to detect flaws. Developed for inspecting external structures of Space Station Freedom for damage from micrometeorites and debris from prior artificial satellites. On Earth, applied to inspection for damage, missing parts, contamination, and/or corrosion on interior surfaces of pipes or exterior surfaces of bridges, towers, aircraft, and ships.

Automated Inspection for Remote Telerobotic Operations

This paper reports on automated inspection techniques being researched and developed for surface inspection of remote space platforms. The unique problems of performing visual telerobotic inspection in space are identified, An image differencing method to detect changes to surfaces over a period of time is presented together with a scale-space technique for flaw identification. Examples from a laboratory mockup of space platform modules are presented to illustrate the results.
