Patent number: 11807276Abstract: A method includes determining a target specification map that is associated with a task and that indicates, for each respective region of a plurality of regions around a vehicle equipped with a sensor, a target value of a parameter of the sensor. The method also includes determining a capability specification map that indicates, for each respective region, an attained value of the parameter that the sensor is configured to provide. The method additionally includes comparing the capability specification map to the target specification map to determine, for each respective region, a disparity between the target value and the attained value. The method further includes, based on the comparing, identifying one or more of: a first subset of the plurality of regions where the target value exceeds the attained value or a second subset of the plurality of regions where the attained value meets or exceeds the target value.Type: GrantFiled: November 29, 2022Date of Patent: November 7, 2023Assignee: Waymo LLCInventors: Jeremy Dittmer, Ruffin Evans, Vaibhav Nangia, Benjamin Ingram, Erik Chubb, Yonatan Winetraub
