Abstract:
Embodiments of the present disclosure provide methods for determining an object location of an object. In the method, a group of measurement locations for a group of feature marks in the object are collected from a group of sensors, respectively. A group of estimation locations are obtained for the group of feature marks based on the object location and a group of offsets between the group of estimation locations and the object location, respectively.
