  • Publication number: 20230278589
    Abstract: A method of simulating a sensor in an autonomous driving simulation includes obtaining values for a plurality of attributes of a target object to be sensed by a sensor simulator in the autonomous driving simulation. The sensor simulator may simulate an active sensor that outputs rays to an object and receives reflections of the rays from the object. The method also includes inputting the obtained values for the plurality of attributes to a predetermined reflection rate table to obtain a reflection rate mapped to the obtained values; and generating sensor data corresponding to the target object based on the obtained reflection rate.
