Embodiment Construction
[0029] The drone target speed measurement system of the present invention includes: a satellite receiver, an inertial navigation system, and an aerial photoelectric reconnaissance platform. Among them, the aerial photoelectric reconnaissance platform is installed on the UAV in an upside-down manner. During the flight of the UAV, its position and attitude are changing. The stable tracking function of the aerial photoelectric reconnaissance platform can isolate the jitter of the optical axis in the inertial space caused by the attitude movement of the carrier and other disturbing moments, so as to ensure the acquisition of clear image.
[0030] After obtaining the image of the target of interest, the image tracker of the aerial photoelectric reconnaissance platform starts to work, keeping the target in the center of the field of view of the visible light camera to achieve stable tracking of the target, such as figure 1 shown. When measuring the speed of the target, the optical...
