Calibration of low-cost triaxial magnetometer

Particle Swarm Optimization Algorithm Based Low Cost Magnetometer Calibration

ABSTRACT: Inertial Navigation Systems (INS) consist of accelerometers, gyroscopes and a microprocessor provide inertial digital data from which position and orientation is obtained by integrating the specific forces and rotation rates. In addition to the accelerometers and gyroscopes, magnetometers can be used to derive the absolute user heading based on Earth's magnetic field. Unfortunately, t...

Fall Detection Algorithm Based on Triaxial Accelerometer and Magnetometer

Fall is a precipitous drop from a height, or from a higher position, which may be accompanied by injuries. This is one of the most dangerous and fearful situation in the elderly living. This is the reason, fast and early detection of the fall is very important to save and rescue the people and avoid the badly prognosis. In this article we are presenting a thresholdbased fall detection algorithm...

Low–cost Photometric Calibration for Interactive Relighting

Computer augmented reality is a rapidly emerging field allowing users to mix virtual and real worlds. Our interest is to allow relighting and remodelling of real scenes, using a reflectance estimation method. Most previous work focused on the quality of the results without considering the expense in computation and the price of acquisition equipment. In this paper, we present a low–cost photome...
