We present the design of an all-accelerometer inertial measurement unit (IMU). The IMU forms part of an intelligent hand-held microsurgical instrument that senses its own motion, distinguishes between hand tremor and intended motion, and compensates in real-time the erroneous motion. The new IMU design consists of three miniature dual-axis accelerometers, two of which are housed in a sensor sui...

Robot calibration is a useful diagnostic method for improving the positioning accuracy in robot production and maintenance. An online robot self-calibration method based on inertial measurement unit (IMU) is presented in this paper. The method requires that the IMU is rigidly attached to the robot manipulator, which makes it possible to obtain the orientation of the manipulator with the orienta...

The localization of persons in indoor environments is nowadays an open problem. There are partial solutions based on the deployment of a network of sensors (Local Positioning Systems or LPS). Other solutions only require the installation of an inertial sensor on the person's body (Pedestrian Dead-Reckoning or PDR). PDR solutions integrate the signals coming from an Inertial Measurement Unit (IM...

The proper execution of the sprint start is crucial in determining the performance during a sprint race. In this respect, when moving from the crouch to the upright position, trunk kinematics is a key element. The purpose of this study was to validate the use of a trunk-mounted inertial measurement unit (IMU) in estimating the trunk inclination and angular velocity in the sagittal plane during ...

For the work programme BIOTOPMONITORING VIENNA of the Austrian Health Institute, multi-spectral air-borne scanner data have been recorded in the intention of automation supported identification and classification of forests and green urban areas in Vienna. Before multi-spectral and textural image analysis can be performed, the scanner data have to be geometrically rectified (georeferenced) with...

In this paper, we present various procedures to support a ZUPT-based MEMS IMU navigation application by available external building models and photographs of evacuation plans. In detail, these are approaches for horizontal alignment of the track using the external building shell, for height correction by stair and elevator detection, for the extraction of the initial position and direction usin...

Figure 1 represents the paradigm of laser scanning. A paradigm as generally known focuses on the basics and ignores minor matters. The paradigm of laser scanning can be characterised in the following way: • A bundle of 3D-vectors, positioned by GPS and oriented by IMU • Active sensors Figure 2 illustrates the paradigm of Stereo-Photogrammetry and can be characterized by: • 2 directed bundles, w...

MOTIVATION Foot placement and its variability can serve as indicators of mobility and walking ability as a function of age, injury, and disease in humans. Inertial measurement units (IMU) can potentially quantify foot motion without need for laboratorybased motion capture equipment, and for relatively long bouts of walking during daily living. One limitation is that integration of IMU data is s...

Inertial measurement units (IMU) are commonly used in pedestrian and robotic navigation applications and research. Although many IMUs are commercially available, almost all of them are non-customizable and they process the collected raw data before presenting them to the user. However, this creates a limitation for researchers due to the fact that they have to rely on a set of per-processed dat...

Accurate position and orientation data are the bases for successful navigation. In this paper, we design and analyze the micro-navigation satellite network that share orientation information among the satellite network. Satellites use GPS, IMU and lasers to align with each other, transferring and sharing the accurate absolute and relative orientation information. Our design includes a GPS and I...
