AravisProject
New Infrared Technologies Ltd device support
Hi, I am testing infrared camera Tachyon 16k from NIT. I tried latest Aravis release and also master branch but without success. I am attaching output of arv-test and camera features and screenshots or viewer and QArv. I was able to acquire image in 3rd party viewer. I think the issue is that Aravis does not figure out the resolution which is 128x128 and shows just 0 in arv-test. Any ideas?
Nope. The region seems to be correctly returned by arv-camera-test. Could you attach the output of:
arv-tool-0.6 control SensorHeight SensorWidth Width Height -d device:3,evaluator:3
Sorry, I don't know what goes wrong. It will be hard for me to debug this issue without the device at hand. The reading of the acquisition region seems to work fine. May be the acquisition setup is not standard and should be adapted. The related code is in arvcamera.c.

I am now investigating what is wrong. Does Aravis require variables SensorWidth and SensorHeight in the XML file? According to Genicam SFNC they are recommended but not mandatory. When I compare the XML from camera and simulator which works, this is the difference I see: the camera XML is missing those 2 variables and has only WidthMax and HeightMax.
Thanks for investigating this issue. SensorHeight and SensorWidth are not used by the viewer. I would recommend to try to debug with tests/arv-camera-test first. It is much more simpler to understand than arv-viewer with all that UI related code. As I said previously, my first bet would be a non standard acquisition setup sequence. In order to set a fixed framerate acquisition, a number of features must be set, and this is most of the time vendor dependent. Have a look at the camera documentation.
It is a bit strange there is no TriggerMode and TriggerSelector features.
