The Pi Shield offers a wide range of options:
direct control of the 3d scanner via a browser-based graphical user interface (locally or even remotely)
compatible with the raspberry pi cameras (v1.3, v2.1, HQ), arducam imx519 and various other cameras (see github for more info)
compatible with smartphones and external cameras (via external shutter release)
compatible with many DSLR cameras via USB
easily adjustable to control other scanner builds
optional cloud functionality (analyse photos, cloud processing with one click - coming soon)
currently up to two stepper motors via A4988 drivers
The Raspbian image has been tested on the following devices:
- Raspberry Pi 4, 3B +
The following versions DO NOT work:
- Raspberry Pi B +, A +, Zero
It is recommended to use the Arducam IMX519 with autofocus and 16mpx. as it offers the maximum resolution as well as an adjustable focus. The software also supports the Raspberry Pi Camera v2.1 (8mpx), v1.3 (5mpx) as well as the HQ camera.
The optional ringlight creates shadowless illumination and thus creating optimal lighting conditions.
Any external cameras can be used with an existing, modified remote shutter release. The shutter release can be connected to the front of the control unit and is triggered via an optocoupler.
The software can be easily adapted with just a few clicks to various 2-axis scanner setups. The default settings are optimized for the following setup: OpenScan Classic but it can be easily adjusted to work with different builds like the OpenScan Mini
