In recent years, AR and VR have been developing. The advantage of the virtual world is that objects can be viewed in 3D and real-world information can be shared. However, to accurately reflect real-world objects in the virtual world, it is necessary to take into account the effects of the lighting environment. In this study, we propose a method to obtain the shading information of an object using FFT (Fast Fourier Transform), reproduce the same situation in a virtual space, compare it, and estimate the light source.
