Claim:
1. A measuring apparatus comprising: an optical image input unit configured by a circuit or a computer, to acquire optical image data of a figure pattern obtained by an external pattern inspection apparatus, which inspects a defect of a pattern formed on a target object to be inspected by scanning an inspection region of the target object to be inspected, from the external pattern inspection apparatus, wherein the measuring apparatus is arranged independently from the external pattern inspection apparatus, outside the external pattern inspection apparatus; a design data input unit configured by a circuit or the computer, to acquire design data of the pattern formed on the target object to be inspected; a reference image generation unit configured by a circuit or the computer, to generate reference image data to be compared with the optical image data, by carrying out image development of the design data, independently from an inspection of the defect of the pattern performed by the external pattern inspection apparatus; a positional deviation distribution generation unit configured by a circuit or the computer, to generate positional deviation distribution by measuring a positional deviation amount of the pattern on the target object to be inspected, by using the optical image data obtained from the external pattern inspection apparatus and the reference image data having been generated, independently from an inspection of the defect of the pattern performed by the external pattern inspection apparatus; and an output unit configured by a circuit or the computer, to output generated positional deviation distribution of the pattern on the target object to be inspected, independently from an inspection of the defect of the pattern performed by the external pattern inspection apparatus, wherein the optical image input unit further acquires, from the external pattern inspection apparatus, the optical image data together with position data of the optical image data, which is obtained by the external pattern inspection apparatus while the optical image data is also obtained by the external pattern inspection apparatus, and the positional deviation distribution generation unit generates the positional deviation distribution by further using the position data of the optical image data which has been acquired.
