Mapping image is too small

[eighteight]

I have done a calibration, getting this matrix:

2.74607e-05
-3.65818e-05
-0.000119975
0.504437
1.13116e-05
-1.49632e-05
-0.000132833
0.541646
2.27564e-05
-7.33312e-05
-0.00024209

Now, I am projecting back on a figure (of Vsevolod Meyerhold), but the blob, which corresponds to the figure is too small in the projection:

Also, I don't understand what are those rays coming out of the figure blob.

Any insight would be much appreciated.

i don't know what you might be doing wrong. make sure you have set the width and height of the window in the test app to match your projector, that would cause mapping errors. the other rays are the other blobs that you found (like the desk).

Thanks. I simply re-calibrated kinect using a larger area (I moved that white board around the room for that) and the mapping became perfect.
