Configuring Ranger E and D
5 Configuring Ranger E and D
The Ranger E and D can be configured to fit many different applications. This enables
testing of different set-ups and fine-tuning of the parameter values, in order to optimize
the measurement loop and data quality.
The following can be specified when configuring the Ranger:
Selecting configurations and components What to measure
Setting region-of-interest Where on the sensor to measure
Selecting triggering When to make a measurement
Setting exposure time For how long to expose the sensor
Component specific settings How to process the measurement result
before sending it to the PC
All this is specified by setting parameters in the Ranger. Normally, Ranger Studio is used
for configuring the Ranger. The Parameter editor in Ranger Studio retrieves the current
parameters from the Ranger and allows you to modify them. Configurations can be stored
in a file on the PC for later use.
5.1 Selecting Configurations and Components
The Ranger can be used in two different modes:
Image The Ranger functions as a 2D camera and delivers grayscale images of
the objects.
Measurement The Ranger functions as a 3D or line scan camera, and delivers the
results from measuring cross-sections of the object.
The Image mode is normally used as a tool for evaluating different configurations of the
Ranger. It is usually not suitable for use in a vision application – for example, the frame
rate cannot explicitly be controlled when running in Image mode.
Parameter files containing configurations for the basic measurement set-ups are installed
with the development software, and these files can be used as a starting point when
configuring the Ranger for your specific application.
A parameter file contains two configurations that make it possible to use the Ranger in
both Image and Measurement mode. The parameters that affect the Ranger in Image
mode are contained in the Image configuration, and the parameters for the Measurement
mode are contained in the Measurement configuration.
The Measurement configuration contains one or more components, which each corre-
spond to a certain measurement type. The Image configuration contains one component.
Each of the components has a number of parameters that are specific for the component,
for example one parameter used for activating and deactivating the component.
When used in Image mode, the Ranger always uses the Image component. In Measure-
ment mode, Ranger D uses the High-resolution 3D component, and for Ranger E there are
up to ten different components available, depending on model. Since the Ranger E is a
MultiScan camera, several measurement components can be active at the same time.
In addition to the configuration and component parameters, there are a two other groups
of parameters:
Ethernet Used for specifying the communication between the Ranger and the PC
System Used for controlling lasers used with the Ranger
