Camera resolution in iOS #5

Closed sokki closed 1 year ago

sokki commented 6 years ago

I am not able to figure out, how to set the right camera resolution in iOS. I get the following log:

018-08-19 12:55:26.443408+0200 helloar[4436:1828117] [info] No predefined camera parameters for device iPhone (Unknown model).

Is this related to https://github.com/artoolkitx/artoolkitx/issues/40 ? Due to cparamSearch.c it should try to curl from https://calibration.artoolkitx.org/app/calib_camera/download.php which does not seem to be offline. But when I sniff the apps traffic through Charles proxy, it doesn't try to connect to artoolkitx.org at all.

Is there any documentation, that could point me into the right direction?

I can't check right now, but quite possible there's no calibration for the iPhone 8 in the database. I'll be publishing the camera calibration tool on iTunes soon, then we can address this (I don't have an iPhone 8 to calibrate with).

sokki commented 6 years ago

I also tested an iPad Air and iPhone SE without any luck. Is there anything I could help with short term? I've an iPhone 8, iPad Air, iPhone SE and a developer account at hand ...

But I still wonder why I couldn't see the app making any request to artoolkitx.org at all. Is there anything else I could have misconfigured?

philip-lamb commented 6 years ago

I should also mention that a negative result (i.e. no device in the online database gets cached by the app for 1 week). So if it failed once and you tested again, you wouldn't see any network traffic on the second attempt. Deleting the app will empty the cache of course.

Good point, thanks! I deleted the app and ran it again. Now I also get Created new camera parameters database. in the logs. But cdp.cloud.unity3d.com is still the only host, the app connects to 🤔

Edit: Nevermind, it seems that your requests bypass the iOS proxy settings, so I could not see stuff in Charles. In Instruments I could see connections going to eden.net.nz:443 which I can't see in Charles.

philip-lamb commented 6 years ago

It uses libcurl for the network connection. I didn't realise that libcurl doesn't honour the iOS proxy settings; which seems like a bug in libcurl.

I've deleted my app and installed again, still cannot get cparam from server :(

I guess we don’t have any camera calibration for that model.

Oh, seeing the above reply https://github.com/artoolkitx/arunityx/issues/5#issuecomment-414311035 thought I would get Created new camera parameters database. too.

You can contribute using the calibration app. It’s in the repo
