Photometric image formation
WebOct 7, 2024 · In this section we describe our method for tackling the point-light Photometric Stereo problem. In particular, we provide both the details of the assumed image formation model and how normals can be predicted for Photometric Stereo images by using CNN’s trained on reflectance samples (also see Fig. 3). 3.1 Point-light Modeling WebNote. 50mm / 46° (and full frame) is the most similar FOV with human eyes. Thus 50mm lens is called standard lens (标准镜头). telephoto lens (长焦镜头，望远镜头): 视野小, 放大率大. short focal lens (短焦镜头，广角镜头); 视野大, 放大率小. Sensor Size. Bigger sensor size, Wider angle of view. Vice versa.
