20 Use Cases
20.1 Using a mvBlueFOX-MLC USB 2.0 camera with
mvBlueLYNX-X
To connect a mvBlueFOX-MLC USB 2.0 camera you will need current drivers for both devices:
Update the mvBlueLYNX-X by using the stable feed on our website:
opkg update
opkg upgrade
1.
Install the mvBlueFOX libraries:
opkg install libmvBlueFOX
2.
Connect the mvBlueFOX-MLC via the powered hub to the USB port. 3.
Finally, start wxPropView. 4.
You should see two devices:
The mvBlueLYNX (serial number starting with
LX
) and 1.
The mvBlueFOX-MLC (starting with
BF
). 2.
The mvBlueLYNX-X is able to acquire images from mvBlueFOX-MLC and mvBlueLYNX-X sensor
simultaneously.
If wxPropView is used for image acquisition CPU load is at 100% that is because wxWidgets (GUI basis of
wxPropView) is not optimized on CPU platform. So it is recommended to just use it for setting up image
acquisition parameters. For getting timing results, you can use MATRIX VISION's standard demo program
LiveSnap
which comes with the camera and does no image display so that you will only get the timings for
the acquisition itself.
20.2 Acquiring a number of images
As described in chapter Acquisition Control, if you want to acquire a number of images, you can use as
Setting -> Base -> Camera -> Acquisition Control -> Acquisition Mode MultiFrame and you have to set the
Acquisition Frame Count.
Afterwards, if you start the acquisition via the button Acquire, the camera will deliver the number of images.
The MultiFrame functionality can be combined with an external signal to start the acquisition.
There are several ways and combinations possible, e.g.:
A trigger starts the acquisition (figure 135). 1.
A trigger starts the acquisition start event and a second trigger starts the grabbing itself (figure 136). 2.
