US 2026/0289818 A1 · AUTONOMOUS DRIVING DEVICE FOR CALIBRATING SENSOR PARAMETER AND CALIBRATION METHOD THEREOF

Abstract

An autonomous driving apparatus includes a sensor for performing sensing based on at least one sensor parameter. The apparatus stories first observation information obtained by identifying objects present in a space in which the autonomous driving apparatus is positioned in the memory based on a sensing value of the sensor. The apparatus obtains second observation information obtained from at least one external autonomous driving apparatus and driving history information of the at least one external autonomous driving apparatus from among objects present in the space. The apparatus adds, based on driving history information of the autonomous driving apparatus and the driving history information of the at least one external autonomous driving apparatus, weight values to each of the first observation information and the second observation information stored in the memory, and calibrates the at least one sensor parameter by comparing first and second observation information added with the weight values.
