I’m curious about what results people are getting with Aravis + USB3 Vision Cameras.
My goal is to be able to use various Machine Vision Cameras in my project without having to do a lot of heavy lifting when switching cameras. So it’s as plug and play as possible. It’s also important because some companies like Basler don’t have 64bit versions of their SDK. It’s also a nice fallback in case there are issues with a Vendors SDK.
Here are the results I got with Aravis 0.5.7 running the arv-viewer. In this test I was using a USB Hub, and I set the usbcore.usbfs_memory_mb to 1000. I did try a PCI-Express USB 3.0 expansion card, and got the same results. As far as I could tell it neither improved or worsened the results.
Basler Pulse 1280x960 Monochrome Camera -> Worked well
Basler Ace Monochrome Cameras -> Worked well
Allied Vision Mako Monchrome Cameras -> Didn’t work
PtGrey Blackfly 1.3MP Mono -> Worked well (latest firmware)
PtGrey Chameleon3 1.3MP Mono -> Worked well (latest firmware)
PtGrey Flea3 Monochrome -> Worked well with some LIBUSB_Errors
PtGrey Flea3 3.2MP Color Camera -> Worked well if I changed the pixel format to RGB8
PtGrey Flea3 8.8MP Color Camera -> Didn’t work. Black Image
PtGrey Grasshopper 3 Monochrome Cameras (various) -> Worked well (latest firmware)
There was a weird glitch where on the PtGrey cameras I had to go back to the camera menu before exiting. If I didn’t it wouldn’t properly stream the next time I ran it. It didn’t do this on the Ubuntu x86 machine I tested.
All in all it seems to work well, but that’s only this version. I had been using the latest version on Github, and I was getting some latency issues with it. Where it would be delayed by a second or so then speed up. But, I may have done something wrong when installing it. There are a bunch of dependencies.
