Three-dimensional reconstruction technology has been widely used in the field of industrial automation. However, traditional 3D reconstruction methods are difficult to obtain accurate results from high-temperature products of industrial production lines such as glass and forgings that are characterized by a single surface structure, high reflectivity and no texture, because these high temperature products generate infrared polarized radiation. We propose a three-dimensional reconstruction method of the target based on infrared radiation polarization imaging. First, we establish an infrared polarization radiation model, and analyze the relationship between the infrared radiation polarization state and the normal vector of the target surface. Finally, we obtain the three-dimensional morphology of the target surface by integrating the normal vectors. The method does not rely on the structure and texture information about the target surface, has low lighting requirements, and can reconstruct the 3D morphology of the target surface with only one data acquisition. Therefore, it is easy to implement and has a wide range of applications.
