Any ideas?

Thanks!

Can you zip up your calibration directory and put it some place where I can download it? Thanks

Hi I am also facing the exact same issue , @unktomi were u able to find out the solution ?

@thundercarrot when I started the calibration I could calibrate for first time correctly but now when i am trying to calibrate again for new location it shows the error message .....

Devender, can you zip up your calibration directory and put it some place where I can download it? Thanks

Hi @thundercarrot

I got this Solve failed error again , I downloaded the fresh code from git & just compiled it without any modification. I am attaching the image of error message. (One kinect one projector)

Thanks
Devender

[thundercarrot]

Try making the projected image larger -- i.e. move the projector back.

Can you zip up your calibration directory and put it some place where I can download it? I will take a look.

Hi Andy ,

Yes, by making projected image larger the error disappeared! I wasted 2 days resolving such a silly thing (I was debugging code ) but than your comment came as a New Year GIFT 😄 Thank u so much

Happy New Year!

Hi,

I'm also getting the solve failed error:
Solve failed
RoomAliveToolkit.ProjectorCameraEnsemble+CalibrationFailedException: Unable to successfully calibrate projector: 0

Here is my calibration directory:

https://www.dropbox.com/s/1q3ou58lvb4dmx1/Calibration.zip?dl=0

Thanks!

[thundercarrot]

Sapratte,

The projected image as seen by the camera is too small. Try moving camera closer.

Also, your projection surface is too flat for the calibration to recover projector intrinsics. Try shooting into a corner or temporarily place some large objects like a box in the scene.

Hi Andy,

Thanks for the fast response! I got the projector and camera calibrated and
I think I have successfully run the sample project.

However I am now at a loss as to how to proceed. I believe you spoke to a
friend of mine, Teddy Seyed about the device communication toolkit (Society
of Devices Toolkit) we've been working on at the University of Calgary. I
want to make a simple map application that links the projected display to a
physical display. Could you give me some tips on how to get started on
linking the RoomAlive toolkit to another application?

Sorry to bother you with this, I just thought it would be faster to get
your help right away.

Thanks,
Sydney

Sydney,

I'm not sure I understand what you're trying to do, but I'll go after "linking the RoomAlive toolkit to another application". You have a couple of options. First, if you have the source code for the application, you could wire it into the ProjectionMappingSample directly. If you do not, your second option is to look at the "desktop duplication" feature of the ProjectionMappingSample, where any application that renders to the Windows desktop can be used as the target view for projection mapping.
