In this paper.the detailed algorithm for directional emissivity correction by 3D object reconstruction is presented.The method is based on photogrammetric Direct Linear Transformation (DL T) with numerical improvements to achieve better convergence.The results of DL T solution are used to correct the qirectional emissivity and introduce the distance dependent transmission of ambient.Presented algorithm was practically tested in multichannel video-thermal system with one thermal and four optical channels.The algorithm is useful in various applications.e.g.: in
