摘要
Purpose - Film is an important recording medium in industry. How to ensure film quality is a problem, because the film is produced in a dark room. Aims to focus on this. Design/methodology/approach - An inspection system based on machine vision is presented which could assure illumination and imaging at 940 nm which is safe for film. Findings - An objective evaluation is given using an image processing method and satisfactory results are obtained. Now, the inspection system is used by the biggest film company in China. Originality/value - This work focuses on an important issue in film production.
