Data streaming via vimba SDK from raspberry pi 4

  • The speed of the camera read out can be controlled via "DeviceLinkThroughputLimit". The test was carried out with two Allied Vision 1800 U-120m (USB3 link) 1280x960 pixel, 16 bit per pixel
    • at 75 MByte/s and two cameras the images get funky
    • at 60 MByte/s and two cameras the images are stable, achieving a frame rate of > 2x20 FPS and a combined (effective) data throughput of > 800 MBit/s
    • the code uses multi-threading and thus keeps slightly more than one of the 4 ARM cores busy
