摘要： The user inclines the apparatus (16) according to the pitch (32) and roll (34) axes to produce inclination signals (θI, φI) which are transformed into corresponding command setpoints (θd, φd) for the drone (10) in terms of attitude of the drone according to the pitch (22) and roll (24) axes of the drone. The drone and the apparatus each determine the orientation of their local reference frame (XlYlZl; XbYbZb) in relation to an absolute reference frame linked to the ground (XNEDYNEDZNED), to determine the relative angular orientation of the drone in relation to the apparatus. Then, the reference frame of the apparatus is realigned on the reference frame of the drone by a rotation that is a function of this relative angular orientation. The realigned values thus correspond to user commands referenced in the reference frame of the apparatus and no longer in that of the drone, which allows for more intuitive piloting when the user is watching the drone.
摘要翻译：使用者根据间距（32）和滚动（34）轴倾斜设备（16）以产生倾斜信号（thetaI，phiI），其被转换成无人机（10）的相应的命令设定点（the tad，phid）根据无人机的俯仰（22）和滚动（24）轴的无人机的姿态。无人机和装置各自确定其相对于与地面（XNEDYNEDZNED）相连的绝对参考框架的其局部参考系（XIIIY1; XbYbZb）的取向，以确定无人机相对于该装置的相对角度取向。然后，通过作为该相对角度取向的函数的旋转，将装置的参考系重新排列在无人机的参考系上。重新排列的值因此对应于在装置的参考系中引用的用户命令，并且不再是无人机的命令，这允许当用户正在观看无人机时更直观地驾驶。

摘要： The drone comprises altitude determination means (134), with an estimator (152) combining the measures of an ultrasound telemetry sensor (154) and of a barometric sensor (156) to deliver an absolute altitude value of the drone in a terrestrial system. The estimator comprises a predictive filter (152) incorporating a representation of a dynamic model of the drone making it possible to predict the altitude based on the motor commands (158) and to periodically readjust this prediction as a function of the signals delivered by the telemetry sensor (154) and the barometric sensor (156). Validation means analyze the reflected echoes and possibly modify the parameters of the estimator and/or allow or invalidate the signals of the telemetry sensor. The echo analysis also makes it possible to deduce the presence and the configuration of an obstacle within the operating range of the telemetry sensor, to apply if need be a suitable corrective action.

摘要： The drone (10) comprises an onboard video camera (14) picking up a sequence of images to be transmitted to a remote control. The user selects an exposure mode such as forward or sideways, panoramic or boom plane, tracking, defining a trajectory to be transmitted to the drone. Corresponding setpoint values are generated and applied to a processing subsystem controlling the motors of the drone. Once the drone is stabilized on the prescribed trajectory (38), the exposure by the video camera (14) is activated and the trajectory is stabilized by an open loop control avoiding the oscillations inherent in a servocontrol with feedback loop.

摘要： A vertical-view camera (16) delivers an image signal (ScamV) of the ground overflown by the drone. Gyrometric sensors (102) measure the Euler angles (φ, θ, Ψ) characterizing the attitude of the drone and delivering a gyrometric signal (Sgyro) representative of the instantaneous rotations. Rotation compensation means (136) receive the image signal and the gyrometric signal and deliver retimed image data, compensated for the rotations, then used to estimate the horizontal speeds of the drone. The camera and the inertial unit are piloted by a common clock (160), and it is provided a circuit (170) for determining the value of the phase-shift between the gyrometric signal and the image signal, and to apply this phase-shift value at the input of the rotation compensation means (136) to resynchronize the image signal onto the gyrometric signal before computation of the retimed image data.

摘要： The drone comprises: a vertical-view camera (132) pointing downward to pick up images of a scene of the ground overflown by the drone; gyrometer, magnetometer and accelerometer sensors (176); and an altimeter (174). Navigation means determine position coordinates (X, Y, Z) of the drone in an absolute coordinate system linked to the ground. These means are autonomous, operating without reception of external signals. They include image analysis means, adapted to derive a position signal from an analysis of known predetermined patterns (210), present in the scene picked up by the camera, and they implement a predictive-filter estimator (172) incorporating a representation of a dynamic model of the drone, with as an input the position signal, a horizontal speed signal, linear and rotational acceleration signals, and an altitude signal.

摘要： The attitude and speed of the drone are controlled by angular commands applied to a control loop (120) for controlling the engines of the drone according to the pitch and roll axes. A dynamic model of the drone, including, in particular, a Kalman predictive filter, represents the horizontal speed components of the drone on the basis of the drone mass and drag coefficients, the Euler angles of the drone relative to an absolute terrestrial reference, and the rotation of same about a vertical axis. The acceleration of the drone along the three axes and the relative speed of same in relation to the ground are measured and applied to the model as to estimate (128) the horizontal speed components of the cross wind. This estimation can be used to generate corrective commands (126) that are combined with the angular commands applied to the control loop of the drone in terms of pitch and roll.
