Methods of Software Data Filtering for Working with Sensors in the Field of Robotics
Dmitrii G. Chirkov, Anastasia D. Stotckaia · 2020
Signals from sensors usually have noise due to the different outside conditions such as vibrations, magnetic and electrical fields and others. For this reason different kind of filters can be used: hardware and software. The paper deals with software implementation of filters for MaxBotix ultrasonic sensors: median filter, moving average filter and low-pass filter. Such algorithms also can be used with other types of sensors. Choosing particular type of filter depends on different factors: signal dynamics, accuracy, loss limit and others.
