NI Vision assistant: Acquire Axis image

[kamocat]

I'm having trouble with the "acquire image from Axis" feature.
When I try to "acquire a single image" or "acquire continuous images", I get the error:


Sequence acquisition returns no errors, but all the images come out black.

I can use the WPI Camera Vis to acquire images with LabVIEW with the default IP address: 192.168.0.90. (This is the IP address used in the NI Vision Assistant as well).


Am I doing anything wrong?

(There are plenty of workarounds, but it'd be nice if this feature worked)

Are you talking about the Acquire Image (Axis IP) camera type? Then you press play or get single image?

I wouldn't expect that error, but if it doesn't work for a given camera, check the account setup on the camera. Also, occasionally the cameras will return a server busy error, but again, I wouldn't expect that to turn into a zero length image data error.

You were right about the configuration.

It appears the NI Vision Assistant only uses the FRC, FRC username/password combination, wheras the WPI code will work with any of three combinations.
