jCalibrationBase

abstract class jCalibrationBase extends Serializable

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

this is extended by jCalibration and jCalibrationE

Abstract Value Members

  1. abstract def pointInPolygon(loc: jCoordinate, sensorId: String, configbc: Map[String, String]): Boolean

    checks if the given Coordinate falls within the ROI for the given intersection

  2. abstract def pointInPolygon(loc: jLocation, sensorId: String, configbc: Map[String, String]): Boolean

    checks if the given Location falls within the ROI for the given intersection

  3. abstract def reProjectionError(imageP: Point, expected: Point, hMatrix: Mat): Double

    re projection error with respect to given sensor calibration usefull metric if the camera calibration is done reasonably well

  4. abstract def tranformBbox(bbox: jBbox, sensorId: String): (jCoordinate, jLocation)

    Transform image coordinates bbox to latitude-longitude based on Homography Matrix for a given sensor-id
    Also transform lat-lon to Global coordinates (cartesian) , with respect to a given origin
    The transform matrix and the origin and initialized from a external configuration
    returns Global coordinates and lat-lon
