Marker motion sim

[DavidYaonanZhu]

Hi,

I tried to run
python simMarkMotionField.py -obj square -dx 0.3 -dy 0.4 -dz 0.5

however, the output image does not contain any markers.

Am I missing something?

I met the same problem, but I think the resultant image should be above. The positions of markers on the membrane are not defined in the sensorParams.py, so that there might be no markers shown in the tactile images.

Hi, so do you figure out what to do? I met this problem too. Does it mean that I should add something in the sensorParam?

I think you can draw marker motions using the field of displacement field.

I recommend you to refer to my forked Taxim for details. A demo pair of tactile images with/without markers are shown below.

Really thanks! And how can I get the picture with mark above? I ran the msimCirclewithmarker.py and msimCircle.py. And I found that there is no compose_sparse_insert in msimCirclewithmarker.py. Is it the one named compose_sparse and if I change to it, it will report the error that contact_mask and sparse_mask are not matched in dimension((480,640) and (900,900)).
And do you know the meaning of the picture below? I still do not understand this. Thanks again.

Sorry for that. I forgot to update the compose directory. In fact, I modify the sparse_compact function to make it compatible with tactile images of the size 480x640 . Now it should work.

The meaning of the three pictures above, as explained by their paper, are the displacement of x, y, z respectively (unit: pixel).
