The invention discloses a three-axis anti-shake aerial photography platform for multi-rotor unmanned hot air airships, comprising: an energy consumption optimization module and a displacement compensation module; the energy consumption optimization module includes a motor control module and a platform locking module; The motor control module is used to control the speed / rotation angle of the motor; the pan-tilt locking module is used to lock the pan-tilt; the displacement compensation module is used to adjust the pan-tilt in real time according to the continuous changes of the flight path and the relative position of the target Attitude, stabilize the staring target, improve the effect of ground reconnaissance and detection; and introduce relative motion into the gimbal control link according to the estimated value of the fused target motion state. The present invention provides a three-axis anti-shake aerial photography platform for multi-rotor unmanned hot air airships. By adopting the smooth operation design of the code disc, the mechanical transmission and the mechanical transmission driven by the platform's azimuth / height angle change can be reduced as much as possible. The output torque of the motor drive required by the limit position, thereby reducing the actual working energy consumption of the motor.
Description
technical field [0001] The invention relates to the field of hot air airships, in particular to a three-axis anti-shake aerial photography head used for a multi-rotor unmanned airship. Background technique [0002] The PTZ is a supporting device for installing and fixing the camera. It is divided into two types: fixed and electric PTZ. The fixed PTZ is suitable for situations where the monitoring range is not large. After installing the camera on the fixed PTZ, you can adjust the level and tilt of the camera. After reaching the best working posture, you only need to lock the adjustment mechanism. The electric pan / tilt is suitable for scanning and monitoring a large area, and it can expand the monitoring range of the camera. The high-speed attitude of the electric pan / tilt is realized by two executive motors, and the motors receive signals from the controller to run and position accurately. Under the action of the control signal, the camera on the PTZ can not only scan the ...
