I connected FLIR A35 and try to acquire the image using image acquisition tool. I am repeatedly getting the below error.
I have configured the hardware as per "GigE Vision Image Acquisition Quick Start Guide" for ubuntu/linux. Using Realtek "Semiconductor RTL8111/8168/8411 PCI Express Gigabit Ethernet" and used jumbo frames (mtu 8000). Increased the packet size (7000) and delay (7.2098e+04) . Even with the code its not working. Still getting the above error "gige: Block/frame 1 is being dropped because a lost packet is unable to be resent. There are several possible causes for packets being lost."
For your information, I was able to acquire the raw greyscale image using the below code,
vid = gigecam('192.168.56.2', 'PixelFormat', 'Mono16');
img = snapshot(vid);
I = imadjust(img,stretchlim(img),[]);
imshow(I);
Only having trouble with image acquisition tool. Any help is more than welcome.
