OpenIPC + INAV interval photography experiment

[RiiPiii]

Hi,

I’ve been experimenting with a small personal project using OpenIPC and INAV and thought I would share it here in case it is of interest.

It adds RC-controlled interval photography using INAV MSP telemetry. Images are stored in separate session directories, with a CSV log, and GPS position, altitude, timestamp and image direction are written into the JPEG EXIF metadata.

To make this work I made a small modification to msposd that exports the latest GPS telemetry to a temporary file. Everything else is handled by separate scripts and a small standalone EXIF writer.

I tested it on a RunCam WiFiLink 2 with INAV and it is working for my setup.

I’m mainly sharing this to get your thoughts on the approach. I’m not suggesting any change to the goals or direction of the OpenIPC project.

If you find any technical issues with the implementation, especially the small msposd modification, I’d be happy to hear your feedback.

It is an old idea to have msposd expose all the telemetry&sensor data acquired from the FC via the msp protocol so that other programs can access it easily. But no much interest in it.
The currently available approach it to start it with --out 127.0.0.1:14560 argument to have it forward the raw MSP packets, but then you will have to parse them.
