Camera Connection...

Postby mkopack » Tue Jul 09, 2013 12:47 pm

Can we get some info about the camera connection? ie., what cameras are supported? Is there something that has to be done software wise to support different cameras? I just got the Raspberry Pi camera board and am wondering if that will work on the UDoo or if I'll need to get something else?

Just curious... I'm planning to use my UDoo quad for robotics applications, and having a camera would be VERY helpful for many of my intended applications.

I am curious about this as well. Most of these dev boards are very picky on what cameras they can actually use...

As far as I remember, the developers have stated that the Raspberry Pi camera is not compatible, instead they're going to offer their own similar camera board.

UDOO will support a 5megapixels OmniVision camera with autofocus based on OV5640 sensor.

In case somebody is interested in a comparison with the Raspberry Pi Camera board: This one uses a OV5647, so there's not a lot of difference. The Raspberry Pi one just seems to be slightly better for low light situations.

So a MIPI interface is what is present on the board? But not just any 5MP HD MIPI camera will work?

What we have here is failure to communicate. :?

Anyhow. Since I'm not getting any traction on the camera connection question perhaps the UDOO forum gods might tell me which cameras or types of cameras will be supported via the UDOOs USB connection? Every USB camera under the sun, certain specs, none?

Not sure about when running Android, but for basic Linux, you'll want a USB webcam that supports UVC (usually the REALLY cheap ones don't, but most mainstream brands like Logitech and such do.) Generally if it says it supports Mac, it'll work on Linux.

I don't know what they currently have in the kernel for the Udoo, so you might also need to recompile the Linux kernel to add in the USB webcam support (we had to do that in the early releases for the RaspPi, but it later got added as a standard item in the OS releases.)

Otherwise, should be pretty straightforward.

If this works at all like the camera option for the Pi, then going the MIPI camera route will be advantageous both from a "won't tie up a USB port" aspect as well as from a "doesn't suck up CPU cycles" one (on the RPi it's the GPU that handles the camera processing.)

And yeah, I REALLY hope that things pick up around here once people get their hands on the boards. The RPi community was REALLY active in the 4 months leading up to the first boards getting out in the wild, and things here have been pretty tame in comparison, but I guess not having hardware on hand makes it tough to really comment on much.

Agreed mkopack .. no hardware and no draft specs yet makes it very difficult for folks to start conversing about options and ideas. Thanks for the feedback though. Yeah, I want to leverage the camera on Android so MIPI interface was my first choice. I figure this is how most devices running Android are accessing the camera so is the most likely OTS option. So far they've listed the OV5640 as the only option which is pretty limiting, but it's a start.

Ok the following depends on what you want to do with the camera, in my case I will need a camera for specific object recognition (I don't need the image displayed or anything). Since camera's usually cause a high CPU load, I've found (for my purpose) a very nice solution: the "Pixy" vision sensor. This is a kickstarter project for a vision sensor that recognizes objects and works stand-alone. In the examples found on the kickstarter page they have connected pixy to a Arduino board but you don't actually need it for the sensor to function. You can program the sensor independently.
I am possitive you can make it work for the UDOO aswell since it just uses normal GPIO (though I believe the high signal of the sensor GPIO is 5volts and as far as Ive understood the UDOO can only take 3.3volts (correct me if i'm wrong) but this is solved easily with some resistors or so:) )
Since this sensor works stand-alone it will save a lot of CPU power of youre board :) for my project this is the perfect solution. Maybe it is something you could use aswell? :)

here is the link to the kickstarter project: http://www.kickstarter.com/projects/254 ... ion-sensor
the kickstarter campaign is still ongoing until September 12th I believe and the sensors should be shipped in November.
