In this paper, we focus on subjective and objective Point Cloud Quality Assessment (PCQA) in an immersive environment study the effect of geometry texture attributes compression distortion. Using a Head-Mounted Display (HMD) with six degrees freedom, establish PCQA database, named SIAT Database (SIAT-PCQD). Our database consists 340 distorted point clouds compressed by MPEG cloud encoder combin...

Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched within the conventional flight envelope for a small UAV. Optimal maneuverability of the inte...

This article focuses on human navigation, by proposing a system for mapping and selflocalization based on wearable sensors, i.e., a laser scanner and a 6 Degree of Freedom Inertial Measurement Unit (6DOF IMU) fixed on a helmet worn by the user. The sensor data are fed to a Simultaneous Localization And Mapping (SLAM) algorithm based on particle filtering, an approach commonly used for mapping a...
