Decide whether telecentric optics are justified by part-height variation, perspective error, edge uncertainty, and the required measurement tolerance. A washer diameter changes in the vision result wh
Calculate profile spacing, motion synchronization, coverage, and measurement margin for a laser-line 3D inspection system. A profiler produces a clean cross-section while the conveyor is stationary, b
Engineer source size, diffusion, collimation, exposure, threshold profile, and edge validation for stable silhouette measurements. A shaft diameter changes when the part moves closer to an ordinary ba
Build a metric mosaic from overlapping camera views by controlling calibration, parallax, synchronization, blending, and inspection coordinates. A stitched image of a large panel looks continuous, but
Separate blur, pose movement, focus change, calibration drift, and sensor-temperature effects with controlled tests and reference trends. Measurements are stable after lunch but biased at startup, and
Understand what subpixel localization estimates, when it improves repeatability, and why it cannot defeat blur, calibration error, or poor edge contrast. A measurement tool reports positions to 0.01 p
