Localization is the most important basic information for unmanned aerial vehicles (UAV) during their missions. Currently, most UAVs use GNSS to calculate their own position. However, when faced with complex electromagnetic interference situations or

In this paper, we propose a novel extrinsic calibration method for camera networks based on a pedestrian who walks on a horizontal surface. Unlike existing methods which require both the feet and head of the person to be visible in all views, our met

The wavefront compensation effect of the micro corner-cube-reflector arrays (MCCRAs) in modulating retroreflector (MRR) free-space optical (FSO) link is investigated by wave-optics (WO) simulation method that is based on the split-step beam propagati

Downlink antenna arraying is an effective method to improve the ground receiving capacity instead of the large-aperture antenna in the future deep space explorations, and that the arraying combining algorithm is the key factor in influencing the syst

Free-space optical (FSO) communication utilizing a modulating retro-reflector (MRR) is an innovative way to convey information between the traditional optical transceiver and the semi-passive MRR unit that reflects optical signals. The reflected sign
