Hello
I recently bought a pop2, and the results I am having have nothing to do with the videos I’ve seen. So, I believe I must’ve been doing something wrong. Could you give me some pointers on some issues or suggest some good tutorial.
In the videos I’ve seen the depth camera image as the object or parts of it in grey and the background red, in mine, the model is either grey or red, depending on the brightness but the background is always tones of grey. As a result I am having really sandy texture, even in the provided model. Is there a software settings problem or a model illumination problem?
Do you scan in a bright room or a dark room?
What is the best way to scan bigger objects feature or marker mode? When I’ve tried the marker mode, I always got the message “too few markers…”, whats the minimum number of markers for a good scan?
As Ivan stated already check the Calibration test first before calibrating and let me know the values you got from that test, do the test 3 times the lowest value is what I need .
You can only get sandy texture on the surface if your calibration is off , or you scanned the bust at a greater distance than 25cm from the object , usually 15 cm distance will give you best looking surface .
Also meshing the model in Revo Studio at maximum level 7 will also give you the sandy surface , lower the level in Revo Studio to 5-6 no more than that. Small scans don’t need maximum meshing values .
Use also denoiser at level 3 .
Stay away from windows light .
Hi PopUpTheVolume,
Thank you for the reply, I did the 3 calibration tests in Revo Calibration, as suggested, and got 0.0443/0.0624/0.0553 for a reference value of 0.5, it seems far from good. I will recalibrate to see if I can get better results.
The calibration results are very good , pls try to scan on turntable with the distance of 15 cm , fuse it at 0.01m, mesh it at level 6 , denoiser at 3 and hole closet and post the result .
If you still get bad result after you will need to recalibrate even if the results of your tests was good , I just want to see if the issue is due to distance or to calibration
I’ve made other calibration, and got results of 0.0792/0.0677/0.0545, now I’ve made some other scan passages with the specs you provided and got this results. What do you think?
Yes, Its definitely better, Thank you for the tips. This surfaces have good definition to work with.
I will try now bigger objects, handheld, since I intent to use the scanner for product design.
Thanks again.
Thank you PopUp . Thank you for your tips, they made a real difference. As you mentioned, I was expecting less orange skin, but the overall result is good enough to work with. I will now try bigger objects, the experiences I did, had big “loss track” problems, but I problably have to move slower, and undo more often.
I tested using a plastic crate, not easy at the beginning. But I sprayed it, and in order to increase the feature recognition, added some painting parkers around the object, so it could anchor the tracking. It worked relatively well. But still lost track frequently and failed some alignments….
Do the different colours of these tracking features (in this case the markers) help to anchor the tracking? Or only the geometry is considered? Do you usually use other objects for tracking reference? I saw some videos with printed platforms to increase the feature recognition alignment.
Is there any way to manually align the initial point of each passage, like the alignment in the revostudio? Sometimes after I paused the scanning, had some difficulty finding the new scan position/alignment, even rotating the model in the preview, to a similar position. A manual alignment would be a great feature to facilitate in these situations.
I need to see the object , what is the size etc
And yes you can use other objects as reference for tracking as that what is needed to even scan anything with .
POP2 standalone scanning volume is 30x30x30 mm so make sure the supporting elements are not smaller than that as supporting volume .
The markets when used need to be used only in marker mode and you need a lot of them , when scanning in Marker mode the object features will be not important .
You can scan individual parts and align the point cloud (after fusing and export) in Revo Studio , you can follow my tutorial or fuse directly only point cloud , just remember your point cloud need to be well scanned without artifacts
You can check simple tutorial of main here
Revo Studio nie have additional option to manual align of your scanned parts , feature and point placement.
