Abstract: A work-in-process inspection system is provided and includes a moving image imaging unit that captures a working motion of a worker and an imaging device that captures an image of a vehicle part that is operated on by a worker. A controller determines a difference between the working motion of the worker captured by the moving image imaging device and a predetermined reference motion, and determines a difference between the image captured by the imaging device and a predetermined reference image. Accordingly, whether a predetermined working process has been performed is determined by comparing an image captured through a 3D scanner to a reference motion.
