چکیده

This paper is concerned with the problem of estimating the relative translation and orientation between an inertial measurement unit and a camera which are rigidly connected. The key is to realise that this problem is in fact an instance of a standard problem within the area of system identi cation, referred to as a gray-box problem. We propose a new algorithm for estimating the relative translation and orientation, which does not require any additional hardware, except a piece of paper with a checkerboard pattern on it. Furthermore, covariance expressions are provided for all involved estimates. The experimental results shows that the method works well in practice.

Tightly Coupled UWB/IMU Pose Estimation, Report no. LiTH-ISY-R-2913

In this paper we propose a 6DOF tracking system combining UltraWideband measurements with low-cost MEMS inertial measurements. A tightly coupled system is developed which estimates position as well as orientation of the sensor-unit while being reliable in case of multipath e ects and NLOS conditions. The experimental results show robust and continuous tracking in a realistic indoor positioning ...

Tight Integration Between IMU and GPS for Sounding Rockets, Report no. LiTH-ISY-R-2929

This report presents integrity monitoring and integration methods for an Inertial Measurement Unit (imu) and a gps receiver. The methods are applied to data from a Maxus sounding rocket used for microgravity research. It is crucial to determine the rocket position during launch to ensure a safe landing location. Today, the navigation relies on imu integration only. Involving a gps receiver enha...

A Planning Algorithm of a Gimballed EO/IR Sensor for Multi Target Tracking, Report no. LiTH-ISY-R-2887

This report proposes an algorithm for planning the aiming direction of a vision sensor with limited field-of-view for tracking of multiple targets. The sensor is mounted in an actuated gimbal on an unmanned aerial vehicle (UAV). Dynamic constraints of the gimbal are included implicitly and a genetic algorithm is used to solve the optimization problem.
