- W3003437811 abstract "We address the problem of non-contact geometrical measurements of hard-to-reach objects that is an important task in various industrial and medical applications. We have developed two small-size prism-based systems for simultaneous acquisition of stereoscopic images by a single sensor. For a correct mathematical description of these systems, we use a ray tracing camera model based on a vector form of Snell’s law. We demonstrate that using the chessboard calibration target allows simultaneous geometrical calibration and image quality assessment. We show that the appearance of chromatic aberrations in RGB images caused by the prism may be significantly reduced by applying separate rectification procedure to each color channel. Experiments confirm that the developed optical systems provide high image quality and the software provides high precision of three-dimensional (3D) geometrical measurements. Described systems may become the basis of small-diameter endoscopic probes for various applications." @default.
