Faster Scan time
For the best results we need 2 image sets per scan, one with and one without projection. One other key succesfactor is that there is no movement between the 2 image sets. The shorter the time between the images is, the less change there is movement.
In the current release of the software the time between the images is a few 100s of milliseconds (~500 depending on what raspberry you are using). I have been working hard on getting this time-between-images lower. This is quite a challenge, as it is not just about taking the images fast in good quality, but also making sure the projection and lighting control happen at the exact right moment.
The good news is that I have been able to make test scans with just 70ms between the images! That is over 5x faster then in the previous releases and I still was able to get good synchronization with the projection system. The test was done on the old Raspberry model b+ models with the 5mp camera, but I have been getting good results with the newer raspberry models and 8mp cameras as well.

The new faster scanning feature will be made available in the next release of the software.
