Why Measurement Fails
3D vision usually does not fail because precision is insufficient. It fails because a physical premise stops holding. Structured light assumes that the surface scatters light diffusely. Triangulation assumes a usable baseline angle. Projected methods assume that ambient light does not drown the signal. When the premise breaks, no amount of parameter tuning brings it back.
The categories below follow the measurement problem. Each page explains the physics, the usual workarounds of existing approaches, and our approach. Each card shows whether the category has published measurements.
If none of them match, request an assessment of your part. We will assess feasibility.
Reflective metal: missing or false points
Specular reflectionPolished stainless, chrome, machined faces. Large dropouts or phantom bumps in the cloud
Published measurements
Why it fails · how we handle it →Transparent parts: missing depth, or the background measured instead
TransmissionGlass, clear plastic, film. Empty in the depth map, or the depth of whatever sits behind
Principle only · confirm with a sample
Why it fails · how we handle it →Dark surfaces: weak return, unstable measurement
Low reflectanceDark plastics, rubber, carbon fibre, matte black coatings. Sparse, noisy or absent data
Published measurements
Why it fails · how we handle it →Limited working distance: accuracy drops with range
Triangulation geometryAccurate at close range, poor at longer range. Large parts, wide fields, safe standoff
Principle only · confirm with a sample
Why it fails · how we handle it →Strong light and outdoors: ambient light swamps the signal
Ambient light swamps the signalUnder skylights, outdoors, in brightly lit areas. Worse by day, and different on a clear day
Principle only · confirm with a sample
Why it fails · how we handle it →Crosstalk between units, and laser power limits near people
Projected-method power and crosstalkTwo cameras contaminate each other. High-power blue structured light cannot sit beside an operator
