Optical Line Tracker –
Interpreter for 2 Cameras, CANopen® / serial / parallel port
HG G-73840

The Optical Line Tracker (interpreting unit) HG 73840 which is part of an Optical Guidance System for Automated Guided Vehicles (AGV) enables travelling along a contrast line on the ground. The Optical Line Tracker interprets the location of this line within the view of the camera and outputs its position with regards to the center of the produced picture. In addition, it is possible to detect branchings from the original course.

The Optical Line Tracker is made for the connection of two (2) PAL standard video cameras with composite video signal, in order to automatically guide a vehicle in two different directions of travel (forwards and backwards). It includes a video multiplex unit.

Advantages

modular structure
connectivity for up to two (2) video cameras
CANopen® and analog output
display of the location of the track via a LED bar or external video monitor
RS 232 service interface for parameter settings and tests with a Laptop/PC
