Kalman Filter Implmentation in Line Follower Robot

[0123456rohit]

Hello, I am making a line follower robot with camera (resolution is 1*128) as a sensor. Please guide me on how to use Kalman filter in this so as to get best performance. Help required urgently!!!

From my experience, kalman filter use multiple input make prediction. By multiple input means it requires more than one sensor data to make the estimation. For example, the sensor is used along with gyro-sensor and accelerometer, then kalman filter maybe really helpful in that case. Anyway, assuming the black line only affect on 2-5 pixel, having 128 pixel is enough to line-follow. In this case, PID would be enough, though some work maybe required for tuning the pid.
