Conventional photometric stereo requires to capture images or videos in a dark room to obstruct complex environment light as much as possible. This paper presents a new method that capitalizes on environment light to avail geometry reconstruction, thus bringing photometric stereo to the wild, such as an outdoor scene, with uncontrolled lighting. We do not make restrictive assumption, and only use simple capture equipments, which include a mirror sphere and a video camera. Qualitative and quantitative experiments indicate the potential and practicality of our system to generalize existing frameworks.
