How does a 3D camera work?

With 3D cameras, three-dimensional information of an object can be recorded using laser profiling, in combination with processes in the camera.
3D laser profiling is based on the triangulation principle whereby a camera monitors the laser line projected onto an object and calculates the height information from the distortion of the line profile.

As the object passes underneath the camera, multiple profiles are used to construct a three-dimensional image. The 3D information can be calculated in the camera or on the host or PC system.

A triangulation or triangulation is a measurement method that makes use of the fact that a triangle is completely determined as one side and the adjacent corners are known. The method was first described by the Dutch mathematician Gemma Frisius .More info: Wikipedia (NL)

In order to generate 3D images, we use Basler's ToF 3D camera and LMI's 3D sensors Gocator series. Below you will find more information.
