FLIR camera connecting both SpinView and Image acquisition toolbox on Matlab

Hi,

I use Matlab to have acquisition of FLIR camera. For example, if the exposure time is locked on SpinView, the line "src.ExposureTime = 3000;" will give error. When I change the exposure time to OFF on spinview, it gave no error.

Though I clear all image objects with delete(imaqfind), the error "Multiple image acquisition objects cannot access the same device simultaneously" appears all the time.

I wonder if SpinView is running in the background even if I closed it. I thought SpinView and Image acquisition toolbox should run separately. Please suggest. Thanks.

I thought SpinView and Image acquisition toolbox should run separately.

They appear to use the same interface to reach the same camera. I would not expect to be able to use them both at the same time.

Coukd you suggest why 'Multiple image acquisition objects cannot access the same device simultaneously' appears though I delete video objects? Is there other ways I could delete previous video objects?

If SpinView is still running, the camera might be detected as being in use.

If SpinView is not still running.. try rebooting the camera.

Hi AT_HYZ,

I understand that you’re having issue with using your FLIR camera with MATLAB, and that even after clearing all the image objects with “delete(imaqfind)” you’re still getting the same error.

Refer to the following points inaddition to what you did to solve the problem:

• After deleting image acquisition objects (“delete(imaqfind)”), use “imaqreset” to reset the Image Acquisition Toolbox.
• Check for other applications accessing the camera through the device list.
• Verify proper camera connection and availability in MATLAB using “imaqhwinfo”.
• Update FLIR camera drivers.

Please refer to the following MathWorks documentation link for more information on “Creating Image acquisition objects” and FLIR camera driver:

Hope this helps!
