PROJECT TOPICComputer Vision & Embedded AI
Defect Profiling Laser System
A precision metrology concept examining optical laser sheet triangulation to calculate roundness, diameter variance, and surface pitting across machined shafts mounted on rotary chucks.
Optical Non-Contact Shaft Metrology
- ✓Measures shaft concentricity, taper, and surface grooves without touching finished metal.
- ✓Correlates rotational encoder positions with micron-precision laser height measurements.
- ✓Generates full 3D cylindrical surface profiles in seconds.
The Engineering Challenge
Problem / Objective
Dial indicator gauges require physical contact that can scratch finished surfaces, and manual measurements slow down production batch checks.
