Orbital rendezvous and docking of two spacecraft is a topic of continued interest to NASA. For crewed missions, it is frequently the case that the target is cooperative (i.e., is equipped with some sort of navigation aid). If one of the relative navigation instruments is a Flash LIDAR,...

Visual odometry (VO) refers to the estimation of vehicle motion using onboard cameras. A common mode of operation utilizes stereovision to tri angulate a set of image features, track these over time, and infer vehicle motion by computing the apparent point cloud motion with respect to the cameras. It has...

Machine learning techniques have shown considerable promise for automating common visual inspection tasks. For example, Support Vector Machine (SVM) classifiers that have been learned from labeled training data deliver strong detection performance both for finding human faces in...

A software application detects the heart rate of an individual by using a real-time video stream from a common camera connected to their computer. This involves no contact between the user and the camera, or calibration between individual users. NASA’s...

In their quest for better helmet technologies to keep soldiers and marines safe on the battlefield, researchers at Natick Soldier Research, Development and Engineering Center are making a "HEaDS-UP" play.
