This paper describes a robust localization approach for a moving target based on RGB-depth (RGB-D) camera and 2D light detection and ranging (LiDAR) sensor measurements. In the proposed approach, the 3D and 2D position information of a target measured by RGB-D camera and LiDAR sensor, respectively are utilized to find location of target by incorporating visual tracking algorithms, depth information...
This paper describes a novel approach to estimating the position of target based on fusion of RGB-depth camera and 2D light detection and ranging (LiDAR) sensor measurements. In the proposed approach, the 3D and 2D position information of target measured by RGB-D camera and LiDAR sensor respectively are utilized to find location of target by incoporating visual tracker, depth information and vision-LiDAR...
To design the optimal lunar landing trajectory, the periapsis of de-orbit burn phase is usually used as a starting point of the powered descent phase. And the optimal problem is constructed based on the initial states at this point. For this optimal problem, some kinds of result trajectories have the increase in their own altitude at the early stage to earn the enough time to reduce their huge horizontal...
For the interplanetary mission, the spacecraft must require the trajectory correction maneuver (TCM) to reduce the trajectory error due to the influence of unexpected external perturbation forces. There are many kinds of researches focused on these TCM techniques for the impulsive thrust. Among them, the B-plane targeting method is mainly applied to the interplanetary mission as TCM method. However,...
The interest in the production of stereoscopic contents is growing rapidly. High quality stereo material can be produced using vertical stereo camera rig but complex color discrepancies occur because of the optical characteristic of the half mirror. These discrepancies may severely increase an audience's sense of fatigue if s/he watches these stereoscopic contents for a long time. The color matching...
Todaypsilas high-resolution imaging satellites have complicated missions with an agility capability. For this reason, interesting and studying of the optimization problem of satellite mission scheduling have been increased since 1980s. This paper describes the results of mission scheduling using a genetic algorithm. In this paper, the feasibility of applying the genetic algorithm to the satellite...
The genetic algorithms (GAs) have been recently used in many design problems including an orbit design and trajectory optimization problems due to their global search capability and the robust characteristics. Furthermore, the GAs do not require convenient analytical representations of the problem any more. For this reason, the GAs can provide good solutions to the orbital dynamics design problem,...
