HoloLens Spectator View allows capturing high quality photos including the mixed reality contents as seen by other HoloLens users. To test the complete system setup, the next step is running the supplied sample app in Unity.
Based on my previous two blog posts, calibration of the HoloLens in relation to the DSLR camera has been successfully completed. If you need to complete these steps, check out Part 1 and Part 2 first.
Spectator View Calibration Data
The calibration app saved its calculated data file to your Documents\CalibrationFiles folder. Copy the CalibrationData.txt file to the Assets -folder of the Sample project that is part of the HoloLens Companion Kit / Spectator View GitHub repository.
The following screenshot shows the contents of the CalibrationFiles directory, where the app saved both the screenshots of the Canon EOS camera, as well as from the HoloLens. The txt file in the directory is the data file you actually need for your app.
