I have a class project where I wan't to capture a 20MP image with a Raspberry Pi. I have a minimal budget and I came accross this affordable 20MP camera: https://www.get-cameras.com/USB-Camera-IMX183-MER-2000-19U3C
Apparently it should work on a raspberry Pi according to their website https://www.get-cameras.com/FAQ-ARM-Board-WITH-USB3-Camera
I was wondering if somebody has already some experience with connecting USB3 cameras on the USB2 port of the Raspberry and if Yes, which camera did you use? Does somebody has experience with high resolution cameras on a Raspberry Pi? I just need to capture 1 image per second, so the bandwith is limited.

 

Note camera, for good reason, is using USB 3.0, the Pi is only 2.0 ?
So might be a challenge for real time video. Capturing specific frames
should be OK. The settings in raspvid might not be able to handle a
20 MP camera though, you would have to check into OS site system
manual for Raspian OS. Or whatever OS is used.

Regards, Dana.

 

Dear Dana,

Thank you for you answer. I looked it in the manual, and that somewhat helped me, however I decided to contact the manufacturer.
The manufacturer claims their final and english (now still Chinese) version of their driver/SDK will be released at the end of September, besides
they also say that usb3.0 cameras can support the armv7 platform, so the Raspberry Pi as well.

Oscar

Yes, but sounds like they will throttle frame rate down to USB 2.0 specs
of the Pi. You can calc that off 20 MP and color depth to calc a frame,
then using USB 2.0 data rate find what max frame rate will be.

Yes this is indeed what happens. The raspberry Pi3 has a USB2 port, so you will achieve 2fps with a 20MP camera. If you take the raspberry pi4 you have a usb3 port. However that port does not support the full bandwith of the USB3, therefore you can not acieve 19fp but approx 10-12fps using the 20MP camera.
