System and method to combine input from multiple sensors on an autonomous wheelchair
Abstract:
The invention discloses a system for controlling the movement of a personal mobility vehicle including a processing unit that receives and processes a location data of one or more obstacles over a period of time, determines a change frequency of change of location of the obstacles during the period of time, and generates a movement state categorization of the obstacles categorizing them into either a dynamic obstacle or a static obstacle. The processing unit further determines a dynamic distance traveled by the dynamic obstacle during the period of time, the velocity of the dynamic obstacle, determines movement probability data that relates to the probability of movement of a static obstacle based on the change frequency of change of location, and, determines velocity prediction data of a dynamic obstacle based on the velocity of dynamic obstacles during various time intervals of the time period.
