    Machine vision technology has been successfully applied into various automated production lines in developed countries in the past years, and recently replaces lots of operators in the assembly production lines of China. Currently, the worldwide manufacturers are encountering the new problem: the increasing cost of the human labor for cosmetic defects inspection is conflicting with the increasing quality demand from the end consumers. The manufactures must spend huge amount of money on hiring workers to perform cosmetic defect inspection. Machine Vision is the most feasible direction for solving this problem, but most of the existing vision technologies are usually only good at dimensional measurement. Some commercial software providers try to build in cosmetic defect inspection modules, which are either template matching based or inflexible coding approaches. Their software cannot fulfill the high requirement of cosmetic defects inspection due to low robustness, long trial run time, and high knowledge requirement in certain domain. Therefore, this project proposes deep machine vision platform technologies to empower the vision application for defect inspection. Along these lines, the project team propose the following IP protected platform technologies to tap the market requirement, including: (1) rapid vision application development technologies for vision measurement software; (2) deep learning defect detection technologies which discover the defect detection rules from a set of vision training data, rather than manually designed by the vision engineers; (3) deep learning based defect classification technologies for advanced defect analysis; (4) 2.5D/3D glass inspection illumination and capture technologies. The proposed technologies can be widely used in different industries, such as consumer electronics (CE) manufacturing, semi-conductor manufacturing, etc. In particular, for CE industries, the major manufacturers locate in China and the revenue is increasing rapidly by years. Taking the mobile phone display manufacturing as example, more than 81% of the products are made in China. The proposed platform technologies can help manufacturers to build up vision solution for inspection purpose in a quick and low cost way. Furthermore, the deep machine vision platform technologies can help the users save 50% of vision application trial run time and reduce 30% of total cost.
