Claim One:
1. An optical displacement measurement system of an optical cutting method for measuring a profile shape of a measurement target by a triangulation method, the optical displacement measurement system comprising: a light projection unit for radiating light on the measurement target along one direction; a light receiving unit for receiving reflected light from the measurement target and for generating captured image data indicating an image of the measurement target based on an amount of received light; an imaging setting unit configured to set states of a plurality of imaging parameters for setting an imaging condition; an imaging control unit for controlling the light projection unit and/or the light receiving unit to generate a plurality of pieces of captured image data corresponding respectively to a plurality of imaging conditions by changing a state of any of the plurality of imaging parameters set by the imaging setting unit; a profile generation unit for generating profile data indicating a profile shape based on each piece of generated captured image data; and a reliability calculation unit for calculating, based on each piece of generated profile data or captured image data corresponding to the profile data, a degree of reliability of a profile shape indicated by the profile data.
