I am trying to use a Sony A6000 for mapping with a Matrice 100 and I'm looking for a way to have the Matrice Trigger the camera as it maps, as well as geo stamps the images.
Is this possible to do?

The Seagull #MAP provides everything needed to connect a Pixhawk to a supported Sony MultiPort™ equipped camera in order to automate camera shutter triggering.

The board supports two trigger modes: AF-T (Autofocus-Trigger, 1 sec pre-AF then trigger) and IS-T (Instant-Trigger, instant trigger as soon as camera locks focus). The mode used is determined by the servo PWM output set in the Camera Shutter Configuration in Mission Planner.

Seagull #MAP also supports camera on/off on Sony “Multi” cameras (only). This feature can be used in missions by adding the commands “Do-Set-Servo” or “Do-Repeat-Servo” in Mission Planner.
