Abstract: Aiming at the great difficulties such as infrared background modeling, a method of implanting real infrared target image into real infrared background image is proposed in this study. First of all, the gray scale of the target image and the background image are used to inverse the radiation brightness of the target, background around the target and the new background which is needed to implant the target. After that, using Stephen Boltzmann’s law, the blackbody equivalent temperature of target and background is calculated based on the radial brightness. According to the temperature consistency, target temperature under the new background is calculated by the blackbody equivalent temperature, and then the gray scale of the target under the new background is obtained. Considering the mutual radiation of target edge and the surrounding background, target edge pixels and background pixels are merged through the process of convolution. In the process of convolution, Gaussian kernel matrix is adopted to blur the pixels between the target edge and the surrounding background. Experimental results show that the method can implant target effectively, with higher image resolution and better preservation of the texture information. Furthermore, the fusion method is based on temperature field consistency which is more reliable. This study is expected to complete the target implantation from a new angle.
