Abstract

The invention belongs to the filed of visual navigation, and discloses a cooperative target designing and locating method for unmanned aerial vehicle autonomous landing. The method is based on the principle of being simple in structure and convenient to identify, having direction guidance, and facilitating accurate locating under the affine transformation condition, the shape, size, color, position arrangement and radiation band and power of the cooperative target are designed, and then an identification scheme of the cooperative target is designed. The identification scheme comprises 5000-meter far distance naval vessel position detection, 1000-meter middle distance runway plane locating and 500-meter near distance vessel landing position locating. By means of the cooperative target designing and locating method, safety and success rate of unmanned aerial vehicle autonomous landing can be improved, and the designed cooperative target is convenient to identify and locate and high in robustness. By means of computer view, the cooperative target can be fast identified, and unmanned aerial vehicle autonomous landing is achieved.

Description

technical field [0001] The invention belongs to the technical field of visual navigation, and in particular relates to a cooperative target design and positioning method for unmanned aerial vehicle autonomous landing. Background technique [0002] In the field of navigation technology, the existing autonomous landing / landing navigation methods for UAVs include: Global Positioning System (GPS), Inertial Navigation System (INS), visual navigation system and combined navigation system composed of various methods. At present, in the navigation and landing guidance of unmanned aerial vehicles, the most widely used is to use the GPS / SINS integrated navigation system combined with the altimeter to complete, and SINS stands for strapdown inertial navigation system. Among them, GPS is restricted by foreign countries. When it is turned off or interfered, the safety and reliability of the landing / landing system will be greatly affected; the error of inertial navigation will increase in...
