    please see nv.schema , which is used @since v1.0

    this is kept for backward compatibility and is used for json based pipeline

    the key classes representing the json schema

    Calibration
    Message
    Frame and
    Behavior

    There are two schema for sending messages perception layer to Message broker (kafka or IOT hub), The two schema are represented by Message and Frame. Frame is concise in terms amount of bytes sent over the network

    User can configure to use either of the Messaging schema

    jBehavior is specific to the domain we are dealing with, represent object movement & state over period of times

    The edges represents the roadsegment of open street map (OSM). Each edge has unique id

    trajectory is map matched with respect to open street map (OSM) , snappedTrajectory represents the new set of points on the OSM edges, the edges associated with trajectory with the trajectory after map matching are also computed for edge/link speed estimation. Link speed represents the average traffic speed on road link at a given point of time

  12. lazy val finalBearing: Double

    given two end points of the trajectory returns the final bearing

    given two end points of the trajectory returns the final bearing

    For final bearing, simply take the initial bearing from the end point to the start point and reverse it (using θ = (θ+180) % 360).
