  • Calibration
  • CalibrationBase
  • CalibrationE
  • CalibrationI
  • FramesCache

object CalibrationE extends CalibrationBase

reads the calibration information from the JSON config file, and instantiate the transform matrix, ROI etc per sensor

this is alternative to Calibration and used for Euclidean space, the config is broadcast to each of the executors

example usage

 dataset // of Message
	.map(msg => CalibrationE.transform(msg, config))
	.filter(msg => CalibrationE.pointInPolygon(msg.`object`.location, msg.sensor.id, config))
