摘要： A processor-implemented method with sensor calibration includes: estimating a portion of a rotation parameter for a target sensor among a plurality of sensors based on a capture of a reference object; estimating another portion of the rotation parameter for the target sensor based on an intrinsic parameter of the target sensor and a focus of expansion (FOE) determined based on sensing data collected with consecutive frames by the target sensor while the electronic device rectilinearly moves based on one axis; and performing calibration by determining a first extrinsic parameter for the target sensor based on the portion and the other portion of the rotation parameter.

摘要： A traveling route changing apparatus included in a vehicle determines whether an emergency vehicle is present among nearby vehicles located around the vehicle, tracks a movement of the emergency vehicle, determines whether to change a traveling route of the vehicle such that the emergency vehicle travels without being obstructed by the vehicle, generates candidate routes to change the traveling route of the vehicle, evaluate a risk involved with each of the candidate routes, and control the vehicle based on a candidate route having a lowest risk. Thus, the vehicle may travel along a selected candidate route, and the emergency vehicle may travel without being obstructed by the vehicle.

摘要： A slurry composition is used to treat a surface of a target structure including at least one of a first polishing target film and a second polishing target film, which include different materials from each other, by a chemical mechanical polishing (CMP) process. The slurry composition includes: polishing particles; a first inhibitor including a nonionic polymer to selectively bond to the first polishing target film; and a second inhibitor including an anionic polymer to selectively bond to the second polishing target film. A method of manufacturing an integrated circuit device includes: forming, on a substrate, a target structure including at least one of a first polishing target film and a second polishing target film; applying the slurry composition onto the target structure; and treating a surface of the target structure by a CMP process while the slurry composition covers the target structure.
