Development of Sealant Inspection System Using Image Processing with Reduced Effect of Ambient Light

Abstract

In recent years, a variety of manufacturing is being developed. In the factory production line, an automatic inspection system with lower cost and higher precision is needed. Many inspection systems use image processing. However, generally the inspection system using image processing cannot be examined in certain optical condition, i.e., room light or sunlight can greatly affect the performance. Another problem is high cost for capital investment of the inspection system. In order to solve these problems, an image processing method using the YCbCr color space characteristics and cyan light is proposed. Also, an inexpensive system for its implementation is developed. Finally, the inexpensive image processing inspection system for reducing the influence of ambient light can be realized.
