摘要
PROBLEM TO BE SOLVED: To obtain an inline type judgment method for a distortion amount whereby the distortion amount can be judged at an equal station to a station for laser processing. SOLUTION: The method is applied to laser processing whereby a laser light is irradiated to a work to apply a distortion. An irradiation pattern of the laser light at the work is picked up by a CCD camera 32 on an equal axis to the laser light. The obtained image is processed by an image-processing apparatus 35 to obtain data related to light and dark. A distortion amount is judged with the use of the obtained data with reference to a table indicating a preliminarily obtained correspondence of the distortion amount and data related to light and dark.
