Monocular Vision SLAM-Based UAV Autonomous Landing in Emergencies and Unknown Environments

Tao Yang, Peiqi Li, Huiming Zhang, Jing Li, Zhi Li

This paper proposes and implements a monocular vision-based drone autonomous landing system in emergencies and in unstructured environments. In this system, a novel map representation approach is proposed that combines three-dimensional features and a mid-pass filter to remove noise and construct a grid map with different heights.

Anti-UAVs Surveillance System based on Ground Random Fisheye Camera Array

Zhi Li, Tao Yang, Jing Li, Zhuoyue Zhang, Ruikai Liu, Bolin Xie

This paper mainly focuses on monitoring various UAVs in unknown and GPS-denied wide areas. We innovatively construct a novel antiUAVs surveillance system based on ground random fisheye camera array.

Geodetic Coordinate Calculation Based on Monocular Vision on UAV Platform

Zhi Li, Tao Yang, Guangpo Li, Jing Li, Yanning Zhang

This paper mainly studied a method of geodetic coordinate calculation based on monocular vision on UAV platform, which is extension and expansion of the traditional monocular vision measurement method. Our system only needs a monocular camera carried on UAV platform and combines the latest ORB-SLAM algorithm.
