Looking for a cheap embedded computer solution to acquire 4K images from multiple cameras
by sissif from LinuxQuestions.org on (#54BYN)
Hi,
As hinted in the title, i'm working on a mobile robot with a dedicated camera acquisition system for computer vision.
I have now 4 12MPixels industrial cameras and the goal is to trigger them at the same time at 5Hz. The camera grab the frame with Bayer8 format, meaning 1 byte/pixel before conversion, a quick calculation give me a required minimum bandwidth of 1920 Mbps (4 Cameras * 12 Mpix * 5Hz * 8bits/pixel).
The final system need to have 8 cameras in total (but still 4 working at a given moment max), with one embedded computer dedicated only to grab the frames via USB3, convert them to some other format, then send them to a hard drive, it also need to run on ros to communicate with other systems.
The provider of the cameras told me the NVidia TX2 or Xavier will work, but considering their price and what is required, i'm looking for a cheaper solution, maybe by adding a PCIe to USB3 to increase bandwidth capability.
USB3 bandwidth is far from my expertise, i'm looking for any advices, i'll gladly give more informations if needed
thank you for you help.:)
