3D Like human vision, the MD Robotics Instant Scene Modeler (iSM) uses a pair of cameras to observe a scene. As each camera looks at the scene from a slightly different angle iSM can measure distances to hundreds of thousands of points in each scene. When the cameras move, new objects come into the field of view. iSM automatically matches new images, computes camera motion, and seamlessly merges 3D data into one virtual model. The model is calibrated, and instantly provides measurements for immediate viewing or can be saved for future reference.
