hey daniel, thx for your reply. unfortunately there is no chance to measure the whole thing again. your support helped me a lot! i might be quite annoying but might it be possible to take a screenshot of your colourfield and sf display params for the m3c2 comparison. i tried to change the saturation...

btw: when computing the distances between the clouds of the second standpoint, i get completely irregular values. oh man, i really become desperate :( stp2: 6-7: 0.085337 0.026530 6-8: 0.023939 0.010023 6-9: 0.088528 0.027606 6-10: 0.013793 0.006596 6-11: 0.038851 0.014562 6-12: 0.074792 0.023866 6-...

Hey Daniel, thx for testing and the fast reply! At first i have some minor questions: the 2.5D volume calculation tool doesn't seem to be included in v2.6.2 right? you used "project along Y" because of the differences back and forth, right? z would be for differences up and down and x for ...

Hey Daniel, might it be possible that you have a look on the pointclouds? I cleaned them in cyclone and did a export to .pts. I loaded them all together in CC. Marked them and segmented all to the same size via scissor-tool. Then i compared every cloud to the 6h cloud (e.g. 6&7, 6&8, 6&9...

ok when comparing the wall-clouds 6h-to-9h and 6h-to-13h i finally get some logical results :) 6-9h: mean distance: 0,007087 std deviation: 0,003005 6-13h: mean distance: 0,007803 std deviation: 0,004393 so at least there seem to be some minimal deformations the higher the temperature is. is it some...

@daniel: okay at least i got how the C2C computation works. i tried it again by making the compared cloud a bit smaller than the reference cloud, though you are right: i could have just segment both clouds simultaneously with the scissor tool (i think that makes even more sense). yes you are right w...

when i load them separately - so at first just compare 2 wall segments and then compare 2 facade segments - i get more differences/deformations in the facade than in the wall. normally it should be excactly the other way round. i don't get what i'm doing wrong.. here are the results when i register ...

thx for the fast responses: here are 2 screenshots. in the first picture you see both pointclouds one above the other just right after loading them in CC. http://www.directupload.net/file/d/4428/bngdb59j_jpg.htm bizarrely it doesn't seem to work if i try to register both clouds. when i do the regist...

Hey, i've got a problem with the following situation: for my bachelor-thesis i scanned a wall of a river 1 time per hour from the same position. starting at 6 o'clock in the morning with 22 degrees Celsius , i ended up at 13 o'clock with a temperature of 35 degrees. i need to check if there are any ...
