In this work, we show that using the pinhole model as a basic single-camera, image-formation process is not most appropriate for accurate depth calculation. This is particularly true in robotic vision applications where, often, relatively close-range images must be acquired before final handling of objects. Therefore, a non-negligible error is introduced when the distance between lens center and image plane is set equal to the constant focal length regardless of object depth (i.e., a pinhole camera). The case of the lateral stereo-camera geometry is investigated, where an improved formulation for providing depth information is derived, including the related error analysis. |
