Maximum likelihood calibration of a magnetometer using inertial sensors

Magnetometers and inertial sensors (accelerometers and gyroscopes) are widely used to estimate 3D orientation. For the orientation estimates to be accurate, the sensor axes need to be aligned and the magnetometer needs to be calibrated for sensor errors and for the presence of magnetic disturbances. In this work we use a grey-box system identification approach to compute maximum likelihood esti...

ARMY RESEARCH LABORATORY Calibration of Inertial Sensors

____________________________________________________________________ The calibration of accelerometers, angular rate sensors, and inertial measurement units (IMU) increases the accuracy of their measurements. For artillery rounds and most rockets, measurements are acquired while the body is spinning. By the comparison of the sensor output to known input, calibration is accomplished. Calibration...

Modeling and Calibration of Inertial and Vision Sensors

This paper is concerned with the problem of estimating the relative translation and orientation of an inertial measurement unit and a camera, which are rigidly connected. The key is to realize that this problem is in fact an instance of a standard problem within the area of system identification, referred to as a gray-box problem. We propose a new algorithm for estimating the relative translati...

Relative Pose Calibration Between Visual and Inertial Sensors

This paper proposes an approach to calibrate off-the-shelf cameras and inertial sensors to have a useful integrated system to be used in static and dynamic situations. The rotation between the camera and the inertial sensor can be estimated, when calibrating the camera, by having both sensors observe the vertical direction, using a vertical chessboard target and gravity. The translation between...

Fast Relative Pose Calibration for Visual and Inertial Sensors

Accurate vision-aided inertial navigation depends on proper calibration of the relative pose of the camera and the inertial measurement unit (IMU). Calibration errors introduce bias in the overall motion estimate, degrading navigation performance sometimes dramatically. However, existing camera-IMU calibration techniques are difficult, time-consuming and often require additional complex apparat...
