20.10 Working with several camera simultaneously
There are several use cases concerning several cameras:
20.10.1 Creating synchronized acquisitions using timers
20.10.1.1 Basics
Getting images from several cameras exactly at the same time is a major task in
• 3D image acquisitions
(the images must be acquired at the same time using two cameras) or
• acquisitions of larger objects
(if more than one camera is required to span over the complete image, like in the textile and printing industry).
To solve this task, the mvBlueFOX3offers timers that can be used to generate pulse at regular intervals. This pulse
can be connected to a digital output. The digital output can be connected digital to the digital input of one or more
cameras to use it as a trigger.
20.10.1.2 Connecting the hardware
One camera is used as master (M), which generates the trigger signal. The other ones receive the trigger signal
and act as slaves (S).
20.10.1.2.1 Connecting the cameras
The connection of the mvBlueFOX3 cameras should be like this:
