The NASA Vision Workbench (VW) is a modular, extensible, cross-platform computer vision software framework written in C++. It was designed to support a variety of space exploration tasks, including automated science and engineering analysis, robot perception, and 2D/3D environment reconstruction, though it can also serve as a general-purpose image processing and machine vision framework in other contexts as well. The VW was developed within the Autonomous Systems and Robotics area of the Inteligent Systems Division at NASA's Ames Research Center.
