文摘
- •
We describe a method for measuring the dimensions of hot heavy forgings.
- •
A sequence of 2D laser scans generates a point cloud dataset.
- •
The item of interest is isolated from the background via cluster analysis among other techniques.
- •
The processed dataset can yield accurate three dimensional measurements.
- •
This process has been experimentally verified in the laboratory and the workshop.
