DEXI-OS with GPIO and April Tags Enabled

We’ve received a few requests regarding how to enable April Tags in DEXI-OS. This is covered in our April Tag and ROS2 course, but figured we’d get ahead of it by providing a pre-configured image. When flashing and running this image you will have GPIO and April Tags enabled for the 2024 missions.

How do we get access to this course? It says that " This course is closed for enrollment."

Please send an email to support@droneblocks.io and our team will add you to the curriculum. Thank you.

We have tested April Tag scanning on the DEXI, and have discovered that we are unable to read April Tags against a dark grey or black background. We are worried that the background of the bridge will be too dark, therefore meaning that the DEXI will not be able to scan April Tags. Will there be a white background behind the April Tag to create the contrast needed to be able to scan them? Thank you!

First off, great job getting April Tags up and running! I had the chance to fly a test field a couple of weeks ago with DEXI and had no problems. There is a bit of white padding around the marker, but you raise a good point. The bridge I tested on was would without any graphics. Let me chat with @Rohn to confirm this and I’ll report back. Thanks for raising the issue.
