显然,该割线运动模型可以直接作为我们的ekf的预测方程。其中,运动增量(Δsk,Δθk)是可以用编码器测出来的,这个可以作为控制向量输入。 具体来说,假设你的机器人车轮转一圈编码器输出的脉冲数为Nencoder,车轮的周长是circumference,并且在k时刻左右轮的编码器输出分别为lk和rk,那么有: {Δskl=(lk−lk−1)/N...

Moreover, we proposed a strategy to localize a mobile robot using an IMU, a camera and wheel encoders. The EKF is adopted to reduce the sensor noise and bias. Experiments demonstrate that our navigation system is useful and can significantly benefit other reactive navigations....
EKF IMU Fusion Algorithms orien.m uses Kalman filter for fusing the gyroscope's and accelerometer's readings to get the IMU's attitude(quaternion). zupt.m implenments the so called 'zero-velocity-update' algorithm for pedestrian tracking(gait tracking), it's also a ekf filter. ...
we propose a robust data-model dual-driven fusion with uncertainty estimation for the LiDAR–IMU localization system, which integrates the advantages of data-driven and model-driven approaches. We introduce data-driven feature ...

then, the relative angle obtained by IMU is used to replace the data calculated by the encoder to complete the attitude update; then, the EKF filtering method is used to update the speed and position of the robot after data fusion, and...
