12月23日的Sensor fusion应用程序分析

This application demonstrates the capabilities of various sensors and sensor-fusions. Data from the Gyroscope, Accelerometer and compass are combined in different ways and the result is shown as a 3D compass that can be rotated by rotating the device. The major novelty in this application is the fusion of virtual sensors: "Improved Orientation Sensor 1" and "Improved Orientation Sensor 2" fuse the Android Rotation Vector with the virtual Gyroscope sensor to achieve a pose estimation with a previously unknown stability and precision. Apart from these two sensors, the following sensors are available for comparison: - Improved Orientation Sensor 1 (Sensor fusion of Android Rotation Vector and Calibrated Gyroscope - less stable but more accurate) - Improved Orientation Sensor 2 (Sensor fusion of Android Rotation Vector and Calibrated Gyroscope - more stable but less accurate) - Android Rotation Vector (Kalman filter fusion of Accelerometer + Gyroscope + Compass) - Calibrated Gyroscope (Separate result of Kalman filter fusion of Accelerometer + Gyroscope + Compass) - Gravity + Compass - Accelerometer + Compass - Deprecated Android Orientation Sensor (Complementary filter fusion of Accelerometer + Gyroscope + Compass) The source code is publicly available and the link can be found in the About-section.
