Data Logging
●
Data logging will not start by default. It is started from the data logging control panel or API.
The logging frequency is 1Hz.
●
The Orientation changes the heading, tilt and roll output based on how the camera is oriented.
●
IMU zero allows you to set the zero(
0
) value of heading, tilt and roll to the current orientation.
There are also API calls that can be sent via TCP/UDP/Serial or used with scripting:
a. StartLogging and IsLogging:True will confirm logging has started
b. StopLogging and IsLogging:False will confirm logging has stopped
c. Other calls are available through the Rayfin API .
Built-in sensor logging format
Data is logged as a .CSV in the /Media/Data folder. A new file is started each day for data logging.
The camera has a built-in IMU and optional built-in depth and water-temperature sensor. If a NMEA
Altimeter is connected to the camera Aux port then it will log and show that on the camera UI as well.
The format for the SCF string is shown below.
*Depth is logged in the $--SCF string when the camera has a built in depth sensor.
