Calibration is not working on Epson Moverio BT-300

Hello,

 

During my evaluation of the Wikitude SDK for developing an AR-application for the BT-300 I have got some issues with the Wikitudes eye calibration tool.

 

I have tried to calibrate the BT-300 with the build in calibration tool from the sample apps but the calibration seems to be wrong. I have tried to calibrate it several times but neither of the calibrations were usable. The rectangle was way too small and did not overlay the picture. Furthermore, sometimes after the calibration procedure the orange rectangle was not visible because it was too small or the calibration was not precise.

Did someone already manage to calibrate the BT-300 or is it in general not yet working?

 

I will very much appreciate your support and looking forward to hearing from you.

Hello Andreas,


we currently don't officially support the BT-300 as we didn't fully test it with our SDK.


We will release a new version of our SDK quite soon and we improved the calibration for smartglasses in this release. There is a good chance that this will fix your issues.


Hope it will work for you!


Best,

Peter

Can you help me witch calibration?

Hi Xi,


which video tutorial are you using? Did you check our how-to and follow the steps described there?

Peter

Hi Peter,

Yes, I looked at that. I was using this video. Could you please point me in the right direction of setting up and calibrating my glasses because the how-to does not step through the entire set-up process. 


Thank you.

Xi

Hello Patrick,

We are already aware of this issue with the app crashing and we are currently working on it. However, please note that we still do not officially support BT-300 so even if the crash will be fixed you will still have calibration issues with BT-300.

Thanks

Hello!

Please are there answers for me yet?

Hi, I was trying out the 7.2 Moverio samples now that the BT300's are officially supported - but the calibration doesn't seem to pick up the target image at all. I've tried running the sample app and nothing seems to get picked up which I'm guessing is because of the calibration being off? Any help appreciated!


Thanks,

Keith

Hi,

Hello!

I tried the samples. The calibration is still not working. The border box never turns green regardless of my distance from the target.

Hi Keith,


do you mean that the box displayed in the calibration never turns green? If this is the case please try to move closer to the calibration target image until it is recognized and then move back to align the box with the target. Also make sure that the calibration target image is printed at 100% size.


Best Regards,

Alex

You have get really close to the object when the red rectangle appears then it will detect and turn into green. After that, you can align your green rectangle and continue.

Hello Peter,


can you tell me when the new SDK version will be released? I'm having the same issue as Andreas.


Thanks!
