Abstract：The temperature measurement process of infrared thermal image has a large amount of noise, which has seriously hampered the precision and accuracy of infrared thermal image. In order to accurately detect the correlative parameters of the measured object in the infrared thermal image, a 2D meshless denosing method based on infrared thermal images is proposed. Bilateral filtering, anisotropic denoising, meshless denoising are combined to create a 2D meshless denoising model. The model parameters are estimated by using robust regression algorithm, and realize infrared thermal images with meshless denoising. And it enhances the temperature measurement precision of infrared thermal image. Finally, the feasibility of the proposed method is verified by simulation experiments and the method lays the theoretical foundation for military, scientific research and other areas of temperature measurement of infrared thermal image.
