Components of a 3D scanner system
Fig. 3:
Design of a line scan camera application
The following components are necessary for a typical line scan camera application:
Component
Function
1 Line scan camera
Scans the image line by line and communicates with the frame
grabber.
2 Illumination
Lights up the information carrier/scan area on the passing object.
The Chromasens Corona II illumination system is an ideal
supplementary option for the 3DPIXA camera.
3 Illumination
controller
Controls and monitors the illumination unit. The Chromasens
Corona II illumination has integrated temperature/voltage sensors
which can be read out with the XLC4 controller. By using the XLC4
controller, the illumination unit can be monitored and kept stable.
4 Frame grabber
(PC plug-in card)
The image data are sent to a PC by means of a frame grabber with
a CameraLink interface. The frame grabber establishes the
necessary hardware connection to the PC.
5 PC with GPU and
dongle
The PC serves for subsequent processing of the image data and
can optionally control the illumination system.
6 Conveying unit
Moves the scanned object past the 3DPIXA camera.
7 Speed detection
The speed of the object / conveyor belt can be detected by means
of an optional incremental encoder. The encoder can be connected
either to the 3DPIXA camera or to the frame grabber.
8 Power supply
Both, the 3DPIXA camera and the illumination system, require a
suitable power supply.
