In general photometric stereo is used to obtain 3D model for small objects or material samples with indoor scenes. By collecting the sky video of the time-lapse video, we can obtain reflectance and surface normal on building of natural lighting outdoor scenes. From the sky video, the natural lighting environments, and sun information are obtained Applications of the reconstruction of the time-lapse video are also demonstrated.
