Description
Logs external sensors data into a binary file marking it with local timestamps (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 trigger signals from another Elphel camera. 4. Other sensor (e.g., odometer - 3..5V pulses).
A typical log record has the following format:
[LocalTimeStamp] [SensorData] Examples or parsed records: IMU: [LocalTimeStamp]: [wX] [wY] [wZ] [dAngleX] [dAngleY] [dAngleZ] [accelX] [accelY] [accelZ] [veloX] [veloY] [veloZ] [temperature] GPS:[LocalTimeStamp]: [NMEA sentence] SRC:[LocalTimeStamp]: [MasterTimeStamp]
Is used in Eyesis and Eyesis-4PI. Can be used with any other Elphel camera.
