Full-Speed CMV12000 image sensor recording at 1440fps 1080p
Shane Colton gets the CMV12000 image sensor to record more that 1,000 frames per second at 1080p resolution.
I’m using the CMV12000’s X/Y subsampling mode to trade resolution for frame rate, hitting 1440fps at 2048×1088. The overall pixel rate is a little lower than in 4K (3.2Gpx/s vs. 3.8Gpx/s), so it’s feasible to send this through the same Zynq Ultrascale+ capture pipeline, with some modifications, to record continuously to an NVMe SSD.
With ~4:1 wavelet compression, this writes about 1GB/s to the drive, up to 1000s (16.7min) for a 1TB drive. That would be 16.7 hours of playback at 24fps, though. I figured 30 seconds real-time and 30 minutes of playback was enough water droplet footage for now.
See the video below and the blog post for details on how Shane achieved this feat.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
