Introduction

1 Introduction

The Ranger is a high-speed 3D camera intended to be the vision component in a machine

vision system. The Ranger makes measurements on the objects that passes in front of the

camera, and sends the measurement results to a PC for further processing. The meas-

urements can be started and stopped from the PC, and triggered by encoders and photo-

electric switches in the vision system.

The main function of the Ranger is to measure 3D shape of objects. Depending on model

and configuration, the Ranger can measure up to 35 000 profiles per second.

In addition to measure 3D – or range – the Ranger can also measure intensity and scatter:

Range measures the 3D shape of the object by the use of laser triangulation. This can

be used for example for generating 3D images of the object, for size rejection

or volume measurement, or for finding defects on the object if it has a well-

known shape.

Intensity measures the light that is reflected by the object. This can be used for example

for inspecting print on objects or detecting defects in the objects’ surface.

Scatter measures how the incoming light is distributed beneath the object’s surface.

This is useful for example for finding the fiber direction in wood or detecting

delamination defects.
