In this work a calibration method which is easy to use and is capable of calibrating a combination of a magnetometer and an accelerometer is described. The calibration method accounts for hard and soft iron effects created by the platform, sensor errors like biases, scale factors and non-orthogonalities as well as the relative orientation between the magnetometer and the accelerometer. The algorithm...
This paper discusses the design and implementation of a light-weight thermal camera payload for small fixed-wing UAVs with a pan/tilt mechanism and georeferencing based on a simple autopilot's GPS and IMU. Further, an effective and simple method to accurately calibrate a thermal camera is developed and tested. In order to evaluate the accuracy of the georeferencing algorithm, a test flight was conducted...
Unmanned Aerial Systems are currently in use for a wide variety of applications with digital cameras and thermal cameras, but recent advances in Short Wave Infrared (SWIR) imaging systems or imagers have led to their commercial availability. The SWIR spectrum is a reflected light region and similar to near-infrared (NIR) is invisible to human eyes. The unique properties of this spectrum such as penetration...
