Abstract: This document describes techniques and systems for fusion of object classes. Sensor data, related to an object, can be obtained from different types of sensor systems. Using techniques based on a Dempster Shafer framework, masses of each potential object class based on data from a respective sensor can be calculated. The respective masses of each potential object class, based on the different sensor systems, can be combined to generate a fused mass for each potential object class. Probabilities for each potential object class can be calculated based on the respective fused masses. An assigned object class for the object can be selected based on a probability exceeding some decision threshold. This assigned object class may then be available for an object tracker, an object fusion system, or other vehicle system resulting in a safer driving experience.
