Running vision system with AVT Guppy Camera #7

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What is the expected output? What do you see instead?
We have been modifying the (format/resolution/framerate) parameters to fit the 
camera's 
specification, but we have never been able to run the program using the DC1394 
capture setting. 
We were able however to get parameters and values selecting the "Read from 
file" capture 
setting.

What version of the product are you using? On what operating system?
We are using ubuntu 10.04 LTS, an AVT Guppy camera. According to the camera 
datasheet the 
camera supports a set of settings included in the vision program.

Please provide any additional information below.
Here's the latest entries to my Scrapbook, which includes the issues concerning 
our request:
...
• Capture Settings Parameters: Capture format :auto // use 1394B = true // 
use ISO800 true. 
OUTPUT:
    CaptureDC1394vc Info: got iso channel: 7
    CaptureDC1394     Error: unable to set operation mode. Resuming nevertheless
    CaptureDC1394 Info: using legacy 1394A
    libdc1394   Error: An ISO speed bigger than 400Mbps was requested while the
        camera is in LEGACY mode. Please set the operation mode to
        OPERATION_MODE_1394B before asking for 1394b ISO speeds
    CaptureDC1394v2 Error: unable to set ISO speed!

• Paramteros: Capture format :auto // use 1394B = false // use ISO800 false. 
Errores:
      libdc1394 error: Error: Failed to allocate iso bandwith
      libdc1394 error: Error: Failed to setup DMA capture
      CaptureDC1394v2 Error: unable to setup capture. Maybe selected combination of 
Format/Resolution is not supported?
• Testing Format/Resolution Settings:
∘ Capture format= format7_1(2,3,...,7) produces the OUTPUT: 
     Selected mode (format/resolution/framerate) is not supported by camera

Another user provided the correct configurations for this camera. Need to add 
to documentation.
