Study Notes
Kalman Filter Overview
- The Kalman Filter is a mathematical method for estimating the state of a system from noisy measurements.
State Vector
- The state vector in the Kalman Filter includes the position, velocity, and acceleration of a vehicle when estimating its position.
Measurement Vector
- The measurement vector in the Kalman Filter includes the measurements obtained from sensors, such as GPS, accelerometers, and gyroscopes, when determining the vehicle position.
State Transition Matrix
- The state transition matrix in the Kalman Filter is called the transition matrix or A matrix.
Estimation Method
- The Kalman Filter uses a prediction-correction mechanism to estimate the vehicle position, which involves predicting the state of the system and then correcting it based on the measurement data.
