cvKalmanFilter

Basic

Module: OpenCV

Standard Kalman filter.

Name Type Range Description
Input value inDynamParams Integer 1 - Dimensionality of the state.
Input value inMeasureParams Integer 1 - Dimensionality of the measurement.
Input value inControlParams Integer 0 - Dimensionality of the control vector
Input value inReset Bool When true, filter is reinitialized.
Input value inPredict Bool When true, filter computes predicted state.
Input value inCorrect Bool When true, filter updates predicted state from measurement.
Input value inControl Matrix Control vector
Input value inMeasurement Matrix Value to be used for correction.
Input value inTransitionMatrix Matrix
Input value inPreState Matrix
Output value outState Matrix Set when inCorrect is true
Output value outPrediction Matrix Set when inPredict is true

Errors

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type Description
DomainError inControl must be a matrix of size 1 x inControlParams in cvKalmanFilter.
DomainError inMeasurement must be a matrix of size 1 x inMeasureParams in cvKalmanFilter.
DomainError inPreState must be a matrix of size 1 x inDynamParams in cvKalmanFilter.
DomainError inTransitionMatrix must be a matrix of size inDynamParams x inDynamParams in cvKalmanFilter.

Complexity Level

This filter is available on Basic Complexity Level.
