If you are having trouble using the Image Acquisition Toolbox™ with a GenICam™ GenTL camera driver using the toolbox's
adaptor, try the following:
Install the Image Acquisition Toolbox Support Package for GenICam Interface.
Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.
Verify that the
gentl adaptor loads. You can use the
imaqhwinfo command to list installed adaptors. The
gentl adaptor should be included on the list.
If it does not load, make sure that GenICam is configured correctly using the
For information on installing GenICam, see Software Configuration.
Install the manufacturer-provided GenTL producer. During setup, make sure to uncheck the DirectShow driver installation. If a device is configured for DirectShow, it might not be available to GenTL.
Make sure your environment variables are set. For example, depending on the GenTL producers you have installed, on a 64-bit Windows® system, it could be something like:
GENICAM_GENTL64_PATH=C:\Program Files\LeutronVision\Simplon\bin\cti;C:\Program Files\MATRIX VISION\mvIMPACT acquire\bin;C:\XIMEA\GenTL Producer\x86
Each directory that you list in the environment variables must contain a
DLL file that has a
.cti extension and that exports the
standard C functions that are expected for a GenTL producer. The Image Acquisition Toolbox
gentl adaptor scans these directories for all the CTI
files and then checks whether they export the correct minimum set of
Test the connectivity of your device separately from using the Image Acquisition Toolbox. Use the vendor program included with your device to see if you can detect and acquire images from the camera.
If you are using the GenICam GenTL adaptor with a GigE Vision® camera, it may be that the producers for GigE Vision cameras do not send a

sometimes, after plugging in a new camera, it is not found. Using the
gige adaptor first can resolve this.
