Infrared Image Registration of Circuit Board Based on ROI Mutual information
摘要
Abstract
Infrared image registration of circuit board is a major research content on fault detection system of circuit board by infrared images. The background region gray of circuit board infrared image is monotonous and the outlines of components’ exothermic areas are rough with extensive radial areas that are influenced by environment, which have great effects on registration accuracy and efficiency. Combining these features, this technique can extract exothermic chips’ outlines of circuit board by phase consistency. Then it changes the areas within the outline into infrared image ROI of circuit board by regional increasing methods. Based on ROI image registration, it not only retains image information as much as possible, but also reduces markedly operand mutual information. The experiment shows the image registration algorithm can ensure registration accuracy and enhance registration efficiency drastically compared with not drawing ROI, which has practicality and robustness.关键词
