About

Oleg Alexandrov is a researcher specializing in planetary photogrammetry, autonomous robotic navigation, and computer vision, with a particular focus on space exploration applications. His most significant contribution is his foundational role in developing the NASA Ames Stereo Pipeline, a widely adopted open-source software suite for processing stereo imagery from satellites, rovers, and aerial cameras across Earth and other planetary bodies. This landmark tool has amassed over 447 citations, underscoring its transformative impact on the geospatial and planetary science communities worldwide. Beyond terrain processing, Alexandrov has made substantial contributions to autonomous robotics in space environments, particularly through his work on Astrobee, NASA's free-flying robot aboard the International Space Station. His research on visual localization under challenging lighting conditions and landmark-based navigation has helped enable truly autonomous robotic operations in microgravity — a technically demanding frontier. More recently, he has turned his attention to change detection in space habitats using 3D point clouds, paving the way for robotic caretaking of future deep-space stations like Gateway. His archival work revisiting Apollo-era photogrammetric systems further demonstrates a rare ability to bridge historical spaceflight data with modern computational methods.
