Device and method of anti-unmanned aerial vehicle based on multi-camera tracking and positioning
View Patent ↗A device and a method of anti-unmanned aerial vehicle based on multi-camera tracking and positioning, including: a bracket, defined a center, a circumference surrounding the center and a central axis passing through the center; at least three cameras, the cameras are evenly distributed and inclined outwardly on the circumference of the bracket, and center lines of view of the cameras forms an inverted cone; a directional antenna, configured to be arranged on the central axis of the bracket; an electromagnetic module, configured to be coupled to the directional antenna; a pan-tilt, connected to the center of the bracket and configured to drive the bracket to rotate; and a control unit, configured to control the pan-tilt to track a target and lock on to the target according to the video image provided by the cameras, such that the electromagnetic module is manipulated to attack the target.
1. A device of anti-unmanned aerial vehicle based on multi-camera tracking and positioning, comprising:
a bracket defining a center, a circumference surrounding the center, and a central axis passing through the center;
at least three cameras, wherein the cameras are evenly distributed and inclined outwardly arranged on the circumference of the bracket, and center lines of view of the cameras forms an inverted cone;
a directional antenna arranged on the central axis of the bracket;
an electromagnetic module coupled to the directional antenna;
a pan-tilt, connected to the center of the bracket and configured to rotate the bracket; and
a control unit, configured to control the pan-tilt to track a target and lock on to the target according to the video image provided by the cameras, so as to manipulate the electromagnetic module to attack the target.
2. The device of claim 1 , wherein fields of view of the cameras are all rectangular, and overlapping areas shared by the cameras correspond to the central axis of the bracket, when the target enters the overlapping areas and is imaged in all cameras, it means that the target is aligned by the directional antenna.
3. The device of claim 1 , wherein the larger a radius of the circumference defined by the bracket is, the smaller an angle between the central line of view of the camera and the central axis defined by the bracket is.
4. The device of claim 1 , wherein the bracket is a cross-shaped bracket, and the number of the cameras is four.
5. The device of claim 4 , wherein a gunshot of the electromagnetic gun is set within two hundred meters.
6. The device of claim 1 , wherein the cameras are high definition cameras with infrared function.
7. The device of claim 1 , wherein the directional antenna is a yagi antenna.
8. The device of claim 1 , wherein the pan-tilt is an omnidirectional pan-tilt.
9. The device of claim 1 , wherein the control unit comprises: an image analysis module, configured to analyze the video images provided by the cameras, and to control the pan-tilt and/or electromagnetic module according to an analysis result; a communication module, configured for external communication; and a power supply module, configured for providing a working power.
