Inexpensive and Automatic Calibration for Acceleration Sensors
In this paper, we present two methods for calibration of acceleration sensors that are inexpensive, in-situ, require minimum user interaction and are targeted to a broad set of acceleration sensor applications and devices. We overcome the necessity of orthogonal axes alignment by extending existing calibration methods with a non-orthogonal axes model. Our non-orthogonal method can furthermore b...
متن کاملAutomatic Marker Field Calibration
In many augmented reality applications a marker field (set of markers) is used to define the 3Dcoordinate transformation between the camera and the virtual objects. In most systems, the physical positions and pose of each marker relative to each others need to be measured in advance. This calibration process is often time consuming and inaccurate if done by hand. We present an automatic calibra...
متن کاملAutomatic Calibration of Multiple Coplanar Sensors
This paper describes an algorithm for recovering the rigid 3-DOF transformation (offset and rotation) between pairs of sensors mounted rigidly in a common plane on a mobile robot. The algorithm requires only a set of sensor observations made as the robot moves along a suitable path. Our method does not require synchronized sensors; nor does it require complete metrical reconstruction of the env...
متن کاملTransient calibration of electric field sensors
An electric field sensor calibration system that operates in the time-domain is described and its accuracy is assessed. The system makes use of a broadband, unterminated transient test cell that is simple to construct by comparison with matched TEM or GTEM cells. An advantage of the transient technique is that the frequency response of the test equipment does not have to be characterised. Furth...
متن کاملAutomatic Calibration of 3D Ultrasound Probes
Navigation systems based on intra-operative ultrasound have been introduced for different surgical procedures and interventions. The accuracy of the ultrasound probe calibration is a main contribution to the overall accuracy of the navigation system. Different calibration methods based on phantoms have been introduced. The challenge of the calibration procedure is to identify the phantom struct...
