Camera resolution

Recommended Posts

Posted · Camera resolution

I just purchased my first Ultimaker 3 and should have it in hand within the next fews days.  I was wondering two things while I wait though.  What is the resolution of the camera, and can it be upgraded at a later date (perhaps to HD if it's not, or 4k if it's already HD).  Also, can the camera be used with Octoprint or is it only accessible through Cura?

 

Thanks,  looking forward to being part of the Ultimaker community.

I am not sure upgrading the camera to HD would be all that helpful. For one, it will put a lot of overhead on your Wifi setup feeding a lot of extra stuff and it really only lets you see from a very limited angle. I have found it best for just making sure the print is ok and not failing in some way.

It's barely HD (800X600). You can't connect to it through octoprint (pretty sure) but you can connect to it through any web browser.  Also when connecting through a web browser the frame rate is much higher and the resolution is higher also (higher than other methods - you still only get 800X600).

Change the Xs to your ip address for you UM3.
Here is an actual size 800X600 screenshot of my UM3 at this moment (not printing this very moment):

Thank you both for the information. I guess I could also just set up a raspberry pi camera as well. However, @gr5 your image looks pretty good. I may just use the web interface you wrote about and leave it at that.

You can sort-of connect to it in OctoPrint, but it's not very useful.

 

It is possible to enter the camera URL in your OctoPrint configuration, but the rest of the printer cannot be controlled from OctoPrint. So there's no way to start a print from OctoPrint or to make a timelapse (if that's what you want to do)

Hardware-wise, the camera in the UM3 can actually do 1600x1200, but only at a low FPS (something like 2 frames per second).

@ahoeben Do you know the exact camera type and do you know how to change the resolution in Python code or in configs?

I haven't found anything on it yet.

No, sorry, I don't. I know the camera can do 1600x1200 because when the UM3 was being developed I working for Ultimaker. Back then I was involved in getting the stream visible in Cura. But I know very little about the firmware (or the exact hardware, actually).

 

Edit: I would not be terribly surprised if the camera were at least very similar to this one (since the linux board it interfaces with is an Olimex A20):

i have doubts that it's worth the effort, but there are some instructions in this thread:
