Abstract

The article presents an attempt to develop algorithms to simplify the object movement trajectory obtained from the real-time locating system (RTLS) in order to reduce the amount of data while maintaining sufficient compliance with the original trajectory. Software was developed to collect and process data from RTLS, allowing to apply: Douglas-Peucker, Visvalingam-Whyatt and location instability suppression algorithms. The RTLS and algorithms were tested on the example of trajectories, the location data of which was collected using the Decawave RTLS. As a result of the research, the usefulness of the algorithms was assessed and the recommended parameters were determined, allowing to obtain correct results of determining the location after simplifying the trajectory and suppressing random vibrations, while reducing the amount of processed data.
