Abstract

The present invention relates to a drone platform which enables modularized driving units for controlling motors to be directly installed on drone arms in various forms, can be easily attached to and detached from the main body of a drone, and thus can improve convenience in the management of a drone and significantly reduce purchase and management costs.

Abstract

The present invention relates to a device which is attached to each of a plurality of drone arms provided in a drone to maintain stability while supporting a rotor-rotating motor and can precisely tilt the drone arm by a certain angle, the device comprising: a fixed frame which comprises a first frame for installing a servo motor and a second frame for installing a shaft and is fixedly installed to an end portion of the drone arm; a servo motor which is fixedly installed in the inner space of the first frame so that the axial direction of a rotational axis is the same as the lengthwise direction of the drone arm; a servo horn which is installed to rotate in conjunction with the rotational axis of the servo motor; a shaft which is rotated in conjunction with the servo horn, and simultaneously rotates a tilt portion; and the tilt portion which is rotated in conjunction with the shaft while being coupled to the shaft, and tilts, by a certain angle, the rotor-rotating motor fixedly installed at the upper end of the tilt portion.

Abstract

The present invention relates to a method that switches a drone to flight using visual navigation in a situation in which it is impossible to use a GNSS signal, wherein a camera is zoom-controlled according to the altitude, and a correction coefficient dependent on the zoom magnification can be applied to optical flow calculation for visual navigation to achieve autonomous flight through accurate direction identification and velocity calculation.

Abstract

The present invention relates to a method for correcting an angle error generated in a gimbal, consisting of: calculating an angle error value of the gimbal on the basis of an adjustment value checked when rotation of the gimbal is controlled while identifying and tracking a specific target in a vertically downward image captured by a camera mounted on a drone; and using the calculated angle error value for correction.
