Title: Method for evaluating horizontal speed of drone, particularly of drone capable of performing hovering flight under autopilot
Inventor: DERBANNE THOMAS
IPC: B64C13/20
Filed: 2011-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for evaluating the horizontal translation speed of a drone.SOLUTION: The method operates by estimating the differential movement of the scene picked up by a vertically-oriented camera. Estimation includes periodically and continuously updating of a multi-resolution representation of the pyramid of images type modeling a given picked-up image of the scene at different, successively-decreasing resolutions. For each new picked-up image, an iterative algorithm of the optical flow type is applied to the representation. The method also provides responding to the data produced by the optical-flow algorithm to obtain at least one texturing parameter representative of the level of micro-contrasts in the picked-up scene and obtaining an approximation of the speed. To the parameters, a series of the predetermined criteria are subsequently applied. If the series of criteria are satisfied, the system switches from the optical-flow algorithm to an algorithm of the corner detector type.
