Hi there!

I am trying to acquire images from a custom designed GigE camera with the MATLAB image acquisition toolbox. The camera uses a Pleora NTx Mini Module for the gige connectivity.

The connection goes well, after recognizing the camera, the pixel types are listed but there is a problem with the resolution. In the default Pleora software i set the resolution to, say, 640x480. It all works well, i get a perfect live image.

But the imaqtool shows some weird values for the resolution 16376x16383. Also i can't change the Width and Height. The values for resolution are read-only.

Is this a problem of the Pleora module? Of the xml file it delivers to matlab, when the videoinput object is created?

for any ideas -> thanks in advance, Andrei

Hi! Just in case someone else has the same problem:

Problem solved (or at least half-solved). The guys from Pleora said: The imaqtool is reading the "SensorWidth" and "SensorHeight" parameters from the xml file.

To set those, you need another software tool called AutoGEV, also from Pleora(that's why "half-solved").

Greetings,

andrei

if you set the image size with AutoGEV can matlab acquire images? I have a similar problem, i can get genicam to work, national instruments "measurement and automation" explore to work. matlab imaqtool will recognize i have it attached but fails to preview the image, it thinks the size is as you stated when it is really 1024x768

Andrei & Gerard,

The default for our IPengines is to present the largest possible sensor in the XML file. This allows our customers to get going quickly as they can then change the height and width fields to match what the sensor actually is. For our OEM camera developers we have our AutoGEV tool as Andrei has mentioned which allows you to customize the XML file. One of the first entries that is customized is the sensor size to reflect the actual size in the camera. (for further information see: http://www.pleora.com/our-products/iport-video-transmitters/autogev-xml-development-tool ).

If you need a quick fix Pleora can provide you with a temporary version of the firmware which can reduce the sensor size in the XML file. Please contact Pleora through the support case you already have open (or e-mail support at Pleora) to request this firmware.
