I present in this post an integration test of a high resolution scan, carried out with Revopoint MINI, of a particular / portion of a sculpture, integrated / merged to a complete scan carried out with POP1 of the same sculpture.
To carry out this experiment I used a scan made last year with the first scanner of the POP series (the glorious POP1). The idea is to make a “lighter” 3D scan of an entire sculpture and then merged with parts, with greater detail, scanned at a higher resolution.
The workflow needs some attention. and some work.
As I wrote above, the sculpture was already scanned with POP1. The 3D model is one of the first I made with that scanner. I would like to say a positive word for the first POP of the series that I was able to use with excellent results even on decidedly more complex scans and on larger sculptures. As we know that the tool you use matters, but what matters most is the way you use it. In the sense that even having a very high level instrument, if it is not used correctly and with hard work and with the help of experience, results are not at a good level.
So having as a basis the model (mid / low resolution) made with the POP1, I scanned a portion rich in details: the head of the Madonna.
The scan was done with the MINI.
After having performed the merger of the point cloud (resolution 0.1), it was exported to carry out the alignment with the scan made with POP1.
For this task I used Meshlab.
The new point cloud has been exported to be worked on with Cloud Compare.
In the image below, the difference in “dot density” of the added area, scanned with the MINI, is evident.
Then we proceeded to meshing
The final result compared with between the POP1 model and the POP1 + MINI model.
The area of the added part is highlighted below (in light green)
Below are the comparison pictures of the added part (before and after)
In conclusion, the possibility of integrating Revopoint scanners to obtain a better result is possible, but as always, the procedure must be planned according to the result to be obtained and the subject to be scanned. It is a workflow that must be thought of, not a “one button procedure”.
