Distribute & Erase, a Self-Calibration Algorithm for Ultrasound Based Localization Systems
نویسندگان
چکیده
Most indoor localization systems are based on static sensor nodes with known position. By means of this infrastructure and measured distances to the static nodes, mobile nodes can localize themselves. But a major problem is the manual position determination of all static sensor nodes, since this procedure is time consuming and fault-prone. In this paper, we present Distribute & Erase, a self-calibration algorithm for ultrasound based localization systems. Distribute & Erase calibrates progressively, is fault tolerant, and achieves an accuracy of millimeters.

A New Approach to Self-Localization for Mobile Robots Using Sensor Data Fusion
This paper proposes a new approach for calibration of dead reckoning process. Using the well-known UMBmark (University of Michigan Benchmark) is not sufficient for a desirable calibration of dead reckoning. Besides, existing calibration methods usually require explicit measurement of actual motion of the robot. Some recent methods use the smart encoder trailer or long range finder sensors such ...

The designing of advanced driver assistance systems and autonomous vehicles needs measurement of dynamical variations of vehicle, such as acceleration, velocity and yaw rate. Designed adaptive controllers to control lateral and longitudinal vehicle dynamics are based on the measured variables. Inertial MEMS-based sensors have some benefits including low price and low consumption that make them ...
متن کاملHigh-accuracy ultrasound target localization for hand-eye calibration between optical tracking systems and three-dimensional ultrasound
Real-time target localization in ultrasound is useful in many clinical and scientific areas. For example in radiation therapy tumors can be localized in real-time and irradiated with a high accuracy. To measure the position of an ultrasound target in a global coordinate system or to extend the tracking volume by moving the ultrasound transducer an optical marker is attached to it and observed b...
متن کاملA fully automatic calibration procedure for freehand 3D ultrasound
This paper describes a novel method for calibration of freehand three-dimensional (3D) ultrasound. A position sensor is mounted on a conventional ultrasound probe, thus the set of B-scans can be localized in 3D, and can be compounded into a volume. The calibration process aims at determining the transformation (translations, rotations, scaling) between the coordinates system of images and the c...

Abstract: Distribution economic burden in power system is one of the important and essential issues in power plant production planning. This thesis presents the economic burden for generating power plants with smooth and uneven functions and considering the constraints of the power plant (steam valve, forbidden areas, with and without transmission losses) in a multi-generator power system. The ...
