Introduce a CAD-based visual inspection system, which is designed to measure geometry dimension of sheet metal parts
automatically, such as distance, angle, parameters of circle, etc. The inspection system extracts the features of sequence
images depending on CAD data, and then to reconstruct real 3D of part. It outputs the measurement results against the
various requirements of customer. The main contents of the paper include searching and matching of group of lines with
image space constrains; visual inspection and reconstruction of sheet metal parts based on the photogrammetry
generalized point photogrammetry. The result of experiments shows that the inspection system is robust and achieves the
precision level of repeated manual measurement of an experienced inspector. The arithmetic discussed in the paper has
potential to deal with another object with sharpness edges except sheet metal part.
