摘　　要：针对红外无损检测的特殊性 ,讨论适用于红外无损检测的图像处理 ,设计适合于红外无损检测的图像处理算法 ,重点解决了非均匀加热条件下红外图像的校正和局部对比度不同条件下的缺陷分割问题 .使红外无损检测与评价达到可视化、智能化、自动化 ,以充分发挥红外无损检测的优势 .According to the peculiarity of infrared nondestructive test, image processing and analysis approach suited for that test was proposed. As two focal points, the correction problem of infrared image under non uniform heating condition, and defect separation problem of infrared image under different location contrast condition, both were solved. The results show that both approaches can improve the evaluation ability of the infrared vision testing system, make it visual,intelligent and automatic.
