This week, we’ve made pretty significant progress on our angle calculation algorithm. This algorithm relies on a process called Structure from Motion (SfM). SfM relies on two separate perspectives of the same object, and by extracting key points of the object that are recognizably the same in both images, it can calculate where those points are in 3D space.

The first step in this process is finding and matching those key points, something we’ve been able to do as shown here:

Our algorithm has been able to find and match many points across the image, however you may notice there aren’t many on the antennas themselves. While the other points will still be useful in the calculations to calibrate the camera properties and positions, one of the things we will need to do is ensure that we have enough information about the antennas themselves to reliably find their orientation. We have a few ideas for how to accomplish that, so stay tuned to see how those ideas perform.
