[0049] figure 1A micro-drone 2 according to the invention is shown. The micro-drone (weight about 80 grams) is a helicopter with two rotors 4, 6 spanning about 50 cm. The micro-drone 2 is able to fly autonomously by controlling its linear forward speed and altitude based on optical flow measurements. In particular, the micro-drones are able to follow floors and ceilings and land. The micro-drone has the property of being able to navigate without measurements in an inertial ground reference frame.

[0050] This type of micro- or nano-drones may be suitable for search, reconnaissance or rescue, especially when the terrain is steep or in environments with buildings and / or when GPS navigation is not possible or desirable Task.

[0051] In addition to the two rotors 4, 6, the micro UAV 2 also includes two motors 8, 10, a main body 12 and a ground identification device 14, the two motors 8, 10 are used to drive the rotors. Body 12 defines a longitudinal axis X-X. The body comp...

Abstract

The invention relates to a surface recognition device for autonomous movement of a surface by an aircraft, said device comprising: a probe head comprising at least one sensor for a property which depends on the center-to-surface distance of the probe head distance, each sensor covers a detection zone (ZV) centered on the line of sight (ZC); a system (24) for orientation of the detection zone (ZV) for each sensor; and a controller, which processes data from each sensor and control the system (24) based on said signal. A controller estimates the direction of the perpendicular to the surface and uses the system (24) to rotate each sensor's line of sight (ZC) in a direction spaced by a reorientation angle from the direction of the perpendicular.

Description

technical field [0001] The invention relates to a surface recognition device for recognizing the autonomous movement of a mobile aircraft at a distance from a surface, said surface recognition device comprising: [0002] a) a surface probe defining a coordinate system fixed to the probe, the coordinate system having an origin at the center of the probe, the coordinate system also having a forward axis, a yaw axis, an up axis, the probe comprising a at least one sensor of a quantity that depends on the distance of the center of the probe head from the surface, each sensor covering a detection area centered on the line of sight; [0003] b) an orientation system for orienting the detection field of each sensor by rotating the detection field about the yaw axis; and [0004] c) A controller adapted to receive and process signals from each sensor and to control the system for orienting the detection zone based on said signals. Background technique [0005] Such a device is des...
