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.

Abstract: This document describes techniques, systems, and methods for multi-scan sensor fusion for object tracking. A sensor-fusion system can obtain radar tracks and vision tracks generated for an environment of a vehicle. The sensor-fusion system maintains sets of hypotheses for associations between the vision tracks and the radar tracks based on multiple scans of radar data and vision data. The set of hypotheses include mass values for the associations. The sensor-fusion system determines a probability value for each hypothesis. Based on the probability value, matches between radar tracks and vision tracks are determined. The sensor-fusion system then outputs the matches to a semi-autonomous or autonomous driving system to control operation of the vehicle. In this way, the described techniques, systems, and methods can provide high-precision object tracking with quantifiable uncertainty.

Abstract: This document describes a multiple hypothesis-based data fusion tracker. Each hypothesis aligns to a different pseudo measurement type. The fusion tracker automatically determines, using a predefined error covariance associated with the radar, which pseudo measurement type has a greater chance of being accurate for a current situation. The fusion tracker may rely on either one of two combined radar and vision calculations, or the fusion tracker may ignore the vision-based pseudo measurements and instead, rely on radar pseudo measurements alone. By selecting between three different bounding boxes, a vision angle based box, a vision lateral position based box, or a radar only based box, the fusion tracker can balance accuracy and speed when drawing, repositioning, or resizing bounding boxes, even under congested traffic or other high volume situations.
