| 摘 要： | 主动式红外热波无损探伤技术是一种新型的快速、高效的检测技术.然而,在检测过程中获取的红外图像常常受到加热不均、表面发射率不均以及环境干扰等因素的影响而导致图像质量降低,普遍存在"低对比度、高噪声"等缺点,加大了对缺陷定量识别的难度.为此,在传统的Butterworth高通滤波器的基础上,采用改进的同态增晰技术,选取合适...

| Abstract: | Active infrared thermal wave nondestructive testing(NDT) is a kind of new-style,fast and high-effective testing technology.However,the infrared image acquired by the infrared camera in the experiment always have the problems such as low-contrast and high-noise,which are resulted from uneven heating,uneven surface emissivity and environmental disturbance.Obviously,these problems make the defects quantitative distinguished difficulty.Therefore,an improved homomorphic filtering method was presented in this pap... |
