Abstract
The invention relates to a space coordinate gauge correcting system for a linear laser scanning test head. The system comprises the linear laser scanning test head, a three coordinate measuring instrument, a corrective gauge, a correction algorithm, a measuring system software and a computer system; the linear laser scanning test head is mechanically connected with the three coordinate measuring instrument; measurement data (linear laser scanning test head measurement data L0, L1 and L2 and a coordinate value delta of the three coordinate measuring instrument moving from a position of obtaining the measurement data L1 to a position of obtaining the measurement data L2) are obtained by scanning and measuring the corrective gauge; and by calculating due to the correction algorithm, a data transformation matrix R and a translation transformation quantity T both of which are used for transforming the linear laser scanning test head measurement data L into space coordinate data consistent with a three coordinate measuring instrument coordinate system M are obtained. When the three coordinate measuring instrument is operated and the measurement is performed by utilizing the laser scanning test head, a transformation formula is M=R*L+T; and the linear laser scanning test head measurement data L is transformed into the three coordinate measuring instrument coordinate system data M.
