1. An autonomous vehicle (AV) system comprising:

  • one or more processors of a machine; and

    a machine-storage medium storing instructions that, when executed by the one or more processors, cause the machine to perform operations comprising;

    accessing an incoming data point output by a light detection and ranging (Lidar) unit during operation of the AV system;

    inferring, using a reflectance inference model, a reflectance value of an object based on the incoming data point, the reflectance inference model comprising a mapping of a set of previously collected data points to a coordinate system using range and raw intensity values of the previously collected data points as coordinates, the reflectance value being interpolated from at least two previously collected data points of the set of previously collected data points mapped to the coordinate system, each of the two previously collected data points corresponding to one of multiple known reflectance values; and

    determining one or more characteristics of the object based on the inferred reflectance value.
