This paper proposes a calibration procedure in order to minimize the process time and cost. It relies on the suggestion of optimal positions, in which the calibration procedure takes place, and on position number optimization. Furthermore, this paper describes and compares three useful calibration algorithms applicable on triaxial accelerometer to determine its mathematical error model without a need...
This paper is on measuring a reliable linear velocity using a fuzzy inference system (FIS) for an inertial navigation system (INS). A conventional INS has been utilized to measure yaw angle using a gyro sensor and linear velocity through an accelerometer. However, linear velocity is not accurate because an INS has problems which are error by sensor error and cumulating errors of the accelerometer...
This research was motivated by a need for accurate UAV navigation using camera(s) to augment inertial navigation unit data while flying over, or through an urban environment. The process of position determination using cameras follows a sequence of well defined steps. First features must be found in consecutive-in-time images and then matched across time. The underlying camera motion, as defined by...
