3D technology captures the shape of an object as opposed to 2D which only captures contrast. With 3D shape, you can measure geometric features on a surface regardless of surface color.

In summary, 3D offers:

  • Volumetric measurement (X,Y, and Z-axis) provides shape and position related parameters
  • Contrast invariant, ideal for inspecting low contrast objects
  • Immune to minor lighting variation or ambient light
  • Higher repeatability due to integrated optics, lighting, and pre-calibration
  • Simpler to build multi-sensor setups for large object inspection

That’s just the beginning! To learn more, read our 2D+3D white paper.

How 3D Works

Learn about the fundamental technologies powering our 3D smart sensors.

The story begins with laser triangulation and structured light.

Sensor Types

LMI manufactures five primary types of 3D sensor.

The sensor you choose depends on your specific
application requirements.

Sensor Networking

Sensor networking allows for maximum scan coverage
on large or complex objects.

LMI sensors can be networked up to 24 sensors on one Sensor Networking Hub, with distributed synchronization between sensors.

Test Drive a Virtual Gocator® 3D Smart Sensor

The ultimate sensor emulator is here.

Choose from a variety of application scenarios, then use an exact duplicate of the Gocator interface. Perform measurements on pre-recorded data from a variety of scanned components—all in a web browser-based “virtual sensor” environment. Right from your desktop. Without the need for a physical sensor. You can use Emulator online, via download, or for sample testing of your part.
