Description
Logs external sensors data into a binary file marking it with local timestamps with a micro-second resolution. It supports up to 4 sensor channels at the same time, e.g.: 1. IMU (Inertial Measurement Unit) - orientation in space 2. GPS - geographical location 3. External/Internal trigger signals from another Elphel camera (same as image time). 4. Other sensor (e.g., odometer - 3..5V pulses).
A typical log record has the following format:
[LocalTimeStamp] [SensorData] Examples or parsed records: [LocalTimeStamp]: IMU: [wX] [wY] [wZ] [dAngleX] [dAngleY] [dAngleZ] [accelX] [accelY] [accelZ] [veloX] [veloY] [veloZ] [temperature] [LocalTimeStamp]: GPS: [NMEA sentence] [LocalTimeStamp]: SRC: [MasterTimeStamp]
