Flight state recognition for UAV optical flow velocity measurement
نویسندگان
چکیده
Abstract For the visual navigation and positioning of drones, optical flow algorithm is used to calculate flight speed drone, calculation errors its rotation state, vertical take-off landing state. Based on characteristics data, this paper compares various classification methods. It uses median KNN curve vector simplify feature quantity. Finally, it realizes motion UAV with based SVM algorithm. State recognition experiments have proved that method can effectively identify state UAV, efficiency high.

Inertial Measurement and Filtering of a UAV flight
Unmanned aerial vehicles with high agility and high performance through vertical take-off and landing (VTOL) and multirotor system have been the goal within reach of the mankind since the invention of the motion sensors. This paper details the use of an inertial measurement system consisting of a gyroscope and an accelerometer which was used on a quadrotor we built from scratch and called 'Quad...
متن کاملLaser Doppler Velocity Profile Sensor: Technical Advances for the Optical Flow Rate Measurement of Natural Gas
− The precise measurement of the flow rate of natural gas is of vital economical importance since natural gas contributes highly to the total energy mix. In this paper we report about a laser Doppler velocity profile sensor specifically designed to suit the measurement conditions at the optical test facility of the German natural gas flow rate standard. The profile sensor is an extension of the...

متن کاملState-Space Optical Flow
| Optical ow estimators of motion in image sequences are sometimes found using varia-tional frameworks, which produce partial diierential equations as the estimators. In this paper, we show that certain state-space formulations, solved by linear smoothing theory, lead to these same solutions. The advantages of viewing these problems in this way include explicit stochastic motion models, a prior...
متن کاملUAV In-Flight Awareness Concept
This work proposes an innovative concept, called InFlight Awareness (IFA), expanding the concept of Sense And Avoid and aiming situational awareness in both controlled and non-controlled airspace for unmanned aircraft. From events occurring either internally or externally to the aircraft, the proposed system checks symptoms (taking into account the capabilities of the platform), data from both ...
