Flash and Peep: a Robust Method for Finding and Tracking Displays
نویسندگان
چکیده
We present a two-step method for the localization of displays using cameras and visual markers on screens. Displays can attract attention by flashing in a characteristic pattern and color. Once they’re found by a camera, their exact position can be calculated robustly from a set of markers they show. To make the method numerically stable, a certain degree of redundancy must exist in the environment. We describe how this method was implemented in our experimental instrumented environment and show a simple example of the system in operation.

Robust Control of a Quadrotor
In this paper, a robust tracking control method for automatic take-off and trajectory tracking of a quadrotor helicopter is presented. The designed controller includes two parts: a position controller and an attitude controller. The attitude controller is designed by using the sliding mode control (SMC) method to track the desired pitch and roll angles, which are the output of position controll...

Developing optimal flocking control procedure is an essential problem in mobile sensor networks (MSNs). Furthermore, finding the parameters such that the sensors can reach to the target in an appropriate time is an important issue. This paper offers an optimization approach based on metaheuristic methods for flocking control in MSNs to follow a target. We develop a non-differentiable optimizati...

متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...
