This work describes a physical refraction model stereo vision system calibration. A back projection and a stereo optimization are used to find the cameras axis and distances from its central point to the water tank glass. The system performs inverse triangulation, also known as mesh oriented measurements. In order to evaluate the refraction model performance, laboratory experiments were conducted...
This work proposes a method for calibrating an underwater laser triangulation system. It consists of a complete in-air calibration and an underwater image of a calibrated standard. The refraction between air and water is predicted by estimating the refractive window distance from the camera using the underwater image. This method was evaluated using reference objects and the errors compared with the...
