Main reasons to add DSLR camera(s) to you setup:?
- A single DSLR with wide angle to capture a high quality picture of the person being scanned, for instance as print out when people have visited your scanner.
- Multiple DSLR cameras aimed for instance at the face, to capture a much higher quality mesh/texture for the face region.
If you connected the DSLR up correctly, you do not need to do anything special. The DSLR camera is automatically detected and you can make scans, preview images from all cameras including the DSLR camera(s) and download all the images.

- Raspberry Zero - 5 Euro
- Special Zero to camera adaptor - 5 euro
- Micro USB ethernet Adapter - 4 euro
Compared to the Raspberry Model 3 price of around 35 euros a big saving!
The latest firmware supports the Raspberry Zero V2 with both the 5 and 8 mp camera (v1.3 and v2 cameras).
I have tested multiple Micro USB ethernet adapters. I have found that Micro USB ethernet adapters based on the 88772a chip set work great. I have found that models based on the 9700 chip set DO NOT work!!! The 9700 chip set does seem to work for normal IP traffic, but does not seem to support the multicasting needed by the pi3dscan system.
disclaimer: It looks like the Raspberry Zero v2 is a great candidate for the pi3Dscanner, the only big down side it that it is currently very hard to get. Most suppliers have a "1 per customer" policy at the moment, but I do hope the production will go up and soon we will be able to order freely multiple devices.
As you can see from the below speed test, the Zero performs fine. Sure it is a bit slower then the Model 2 and 3, but is faster then B+ the model we started out with and has proven to work fine.
Important: Because of the speed difference between the various models, do NOT mix models in a single scanner, as this will give synchronization issues.

One very big difference that is instantly visible is the difference in colors. The new v2 camera reproduces significantly better colors.
So is this an easy replacement for the older camera in the 3D scanner. I would say, not directly, To get the best out of the new camera, you would need to shoot closer to the subject. This will cause some challanges. Your poles will be closer, so it might start interfering with projection as they can really not move much closer then 1meter as you will not be able to cover the entire person.
Feel free to download the original source images (untouched). You will find the the images from the V2 camera are for some reason by default horizontally flipped. I will need to have a think about what this will mean for the current scanner design, so more to follow on this subject.
