Latest Patents

One of Zhao’s recent inventions, “System and Method for Unifying Heterogeneous Datasets Using Primitives,” describes a way to combine traffic or driving datasets and organize their records into timestamp-based time series. Bayesian learning methods, including hidden Markov models, can identify traffic primitives—sequences of records representing actions such as turning, stopping, or accelerating. The resulting index allows researchers to query relevant records and use them to train or test learning-based algorithms. The data can also be organized by sensor to support queries involving particular sensor and traffic-primitive combinations.

Another invention, “System and Method for Determining Optimal LiDAR Placement on Autonomous Vehicles,” addresses how to position LiDAR sensors to improve coverage. The method divides a vehicle’s range of interest into equal-sized cubes, models each sensor’s coverage based on its laser configuration, and optimizes sensor locations to maximize the number of captured cubes. It can also determine suitable pitch and roll angles for the sensors.

Career Highlights

Zhao’s patent work connects data-driven methods with practical challenges in autonomous driving. His inventions address both the preparation of driving data for research and the placement of sensors on vehicles.
