INERTIAL DIMENSIONAL METROLOGY

A method of performing dimensional metrology of an object () includes incorporating an Inertial Measurement Unit (IMU-) with an elongate probe () in a portable metroprobe (). A tip () of the probe () has an offset length (L) from an origin () of a coordinate system in the IMU () and position (X,Y,Z) thereof is correlated based on attitude (A,B,C) measurement of the IMU (). The metroprobe () is transported in sequence to a complement of survey points (Pn) on the object () for measuring corresponding coordinates (X,Y,Z) thereof based on measured attitude (A,B,C) of the IMU ().
