HIKROBOT 3D laser profilers and stereo cameras capture height, position and volume with micron-level precision for robot guidance, dimensioning, weld inspection and surface control. Models differ by reference distance, Z-range and scan rate.

Frequently asked questions

What is the difference between a laser profiler and a stereo 3D camera?

A laser profiler scans a laser line across the moving part and delivers exact profiles, while a stereo camera captures a full 3D point cloud of a static scene in one shot.

How accurate are the measurements?

Depending on model and working distance, repeatability reaches the micron range; the datasheet on each product page states Z-axis resolution and linearity.

Which data interfaces are available?

The sensors output profiles or point clouds over GigE; SDKs for common vision libraries and PLC integration are provided.

More questions about 3D cameras

Do laser profilers need an encoder?

For accurate results on conveyors with varying speed, yes – the encoder input keeps the profile spacing constant. Only at truly constant speed can a time-based trigger substitute.

What software processes the 3D data?

The sensors deliver profiles and point clouds through an SDK, and common machine vision libraries process them for measurement, matching and robot integration.

Can 3D cameras guide robots?

Yes. Typical applications are bin picking and depalletizing, where a hand-eye calibration links the camera coordinates to the robot coordinate system.
