1. A method of measuring a relative pose between two cameras, comprising: selecting a time offset value corresponding to a time shift between the two cameras; adding the time offset value to data captured by each of the two cameras in order to minimize the time shift and approximately synchronize the two cameras; and calculating a transformation parameter using the time offset value capable of transforming data in a coordinate frame of one of the two cameras into a coordinate frame of the other of the two cameras so as to obtain the relative pose.
