After I described in my previous post how I built the turntable for the automated image recording, it is now about the control of the stepper motor and the camera. Since a small Raspberry Pi 3 B+ and the programming language Python is ideal for this, the implementation was quite simple. The most important question for me was how fast should the stepper motor start and how many degrees should the plate turn until a picture is taken again. But I will explain all this in the following and show how everything can be configured so that the image recording is easy.<\/p><\/blockquote>\n

Now it’s time to set up the Raspberry Pi and install the necessary packages. So that I as a user can also align and focus the image, the camera image is streamed live over the network from the Raspberry Pi. This way I can use any browser to check the image before starting the automated capture process. Unfortunately, I have not yet designed a web interface to start the capture of the image series. But this optimization will be implemented by me at a later time.<\/p>\n
