Optical Air Flow Measurements in Flight
WebMar 28, 2024 · Optical flow, which can be extracted from a monocular camera, provides a very promising solution for miniaturization. Optical flow refers to the apparent visual motion of objects in a scene relative to an observer. 1 This information tells us not only how fast the camera moves, but also how close it is relative to the things it sees. Flying insects use it … WebMember of the Advanced Sensing and Optical Measurement Branch at the NASA Langley Research Center, Hampton, Virginia. I specialize in laser … WebTime of flight ( ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate). early day motion 908
