Kalman Filters in Geotechnical Monitoring of Ground Subsidence Using Data from MEMS Sensors
The fast development of wireless sensor networks and MEMS make it possible to set up today real-time wireless geotechnical monitoring. To handle interferences and noises from the output data, Kalman filter can be selected as a method to achieve a more realistic estimate of the observations. In this paper, a one-day wireless measurement using accelerometers and inclinometers was deployed on top ...
متن کاملUse of Mems Accelerometers/inclinometers as a Geotechnical Monitoring Method for Ground Subsidence
Accelerometer and inclinometer are inertial sensors capable of measuring corresponding magnitude of Earth gravitational field along the direction of each axis. By means of rotation matrices related to inertial navigation methods, the output values of a three-dimensional accelerometer or a two-dimensional inclinometer can be transformed and processed into the azimuth and dip angle of the monitor...
متن کاملRadar Interferometry for Ground Subsidence Monitoring Using Alos Palsar Data
This paper describes the results using data from ALOS and ENVISAT satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using the differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by the noise due to the spatial and tempor...
متن کاملUnscented Kalman Filtering for Attitude Determination Using MEMS Sensors
This paper presents the results of a quaternion-based unscented Kalman filtering for attitude estimation using low cost MEMS sensors. The unscented Kalman filter uses the pitch and roll angles computed from gravity force decomposition as the measurement for the filter. The immeasurable gravity accelerations are deduced from the outputs of the three axes accelerometers, the relative acceleration...
متن کاملMonitoring Ground Subsidence in Shanghai Maglev Area Using PALSAR and ASAR Data
Shanghai maglev is a very fast traffic tool, so it is very strict with the stability of the roadbed. However, the ground subsidence is a problem in Shanhai because of the poor geological condition and some human-induced factors. So it is necessary to monitor ground subsidence in the area along the Shanghai maglev precisely and frequently. Traditionally, precise levelling method is used to surve...
