Member Function Documentation

produce()

StrongPointer< SensorLogWriter > gem::SensorLogWriter::produce ( int keepLastSeconds )

inlinestatic

Create a SensorLogWriter object.

Parameters

[in]

keepLastSeconds

The number of seconds saved in the log.

Returns

A shared pointer to the SensorLogWriter object.

pushAcceleration()

void gem::SensorLogWriter::pushAcceleration ( LargeUnsignedInteger acquisitionTimestamp, double x, double y, double z )

inline

Push acceleration data.

Parameters

[in]	acquisitionTimestamp	Acquisition timestamp in milliseconds since 1970.
[in]	x	Acceleration on the x axis of the device, G-units.
[in]	y	Acceleration on the y axis of the device, G-units.
[in]	z	Acceleration on the z axis of the device, G-units.

pushCameraFrameInfo()

void gem::SensorLogWriter::pushCameraFrameInfo ( LargeUnsignedInteger acquisitionTimestamp, double exposureTime, double iso )

inline

Push camera frame info.

Parameters

[in]	acquisitionTimestamp	Acquisition timestamp in milliseconds since 1970.
[in]	exposureTime	Duration each pixel is exposed to light in nanoseconds.
[in]	iso	The actual iso value in ISO arithmetic units.

pushGPSPosition()

void gem::SensorLogWriter::pushGPSPosition ( LargeUnsignedInteger acquisitionTimestamp, LargeUnsignedInteger satteliteTime, double latitude, double longitude, double altitude, double course, double speed, double horizontalAccuracy, double verticalAccuracy, double speedAccuracy, double courseAccuracy )

inline

Push GPS position.

Parameters

[in]	acquisitionTimestamp	Acquisition timestamp in milliseconds since 1970.
[in]	satteliteTime	Satellite timestamp in milliseconds since 1970.
[in]	latitude	Geographical latitude in degrees.
[in]	longitude	Geographical longitude in degrees.
[in]	altitude	Altitude above main sea level in meters.
[in]	course	The course of the movement in degrees.
[in]	speed	Travel speed in meter per second.
[in]	horizontalAccuracy	Horizontal accuracy of position in meters.
[in]	verticalAccuracy	Vertical accuracy of position in meters.
[in]	speedAccuracy	Travel speed accuracy in meter per second.
[in]	courseAccuracy	Course accuracy in degrees.

pushRotation()

void gem::SensorLogWriter::pushRotation ( LargeUnsignedInteger acquisitionTimestamp, double x, double y, double z )

inline

Push rotation data.

Parameters

[in]	acquisitionTimestamp	Acquisition timestamp in milliseconds since 1970.
[in]	x	Rotation rate around the x axis of the device in radian per second.
[in]	y	Rotation rate around the y axis of the device in radian per second.
[in]	z	Rotation rate around the z axis of the device in radian per second.

saveLog()

bool gem::SensorLogWriter::saveLog ( const String & outputDir, const String & logName, const CameraCharacteristics & cameraCharacteristics, LargeUnsignedInteger videoStartTimestamp )

inline

Save sensor log.

In the outputDir will be created 2 files "logName.meta" and "logName.sensors"

Parameters

[in]	outputDir	The directory that contains the log.
[in]	logName	The name of the log that will be used for the metadata file and the sensor file.
[in]	cameraCharacteristics	The characteristics of the camera with which the video was recorded.
[in]	videoStartTimestamp	The video start timestamp in milliseconds since 1970.

Returns

False if the input parameters are invalid(output directory does not exist or cannot be created; missing camera characteristics; video start timestamp not in sync with sensors timestamp).
