Study of Registration of Infrared Thermal Wave Images Based on Genetic Algorithm
基于遗传算法的红外热波图像配准技术研究

Because the angle of field of view of an infrared thermal imager is limited and higher resolution is required for the obtained thermal wave image, the thermal wave nondestructive detection of a large object can be implemented only when several images are jointed. For the joint of images, the premise is that the images should be registered precisely. According to the concept of template matching, the Genetic Algorithm (GA) is incorporated into the infrared thermal wave image registration. Through the modification of selection strategy, an adaptive crossover and mutation probability is designed to realize precise registration of thermal images. The experimental result shows that the method can realize the precise registration of thermal images and its operation speed and stability are improved.
