示例1: onSensorChanged
import android.hardware.SensorManager; //导入方法依赖的package包/类
@Override
public void onSensorChanged(SensorEvent sensorEvent) {
if(sensorEvent.sensor.getType() == Sensor.TYPE_ROTATION_VECTOR) {
synchronized (this.mutex) {
float[] quaternion = new float[4];
SensorManager.getQuaternionFromVector(quaternion, sensorEvent.values);
this.imu.getOrientation().setW(quaternion[0]);
this.imu.getOrientation().setX(quaternion[1]);
this.imu.getOrientation().setY(quaternion[2]);
this.imu.getOrientation().setZ(quaternion[3]);
Collection<Double> tmpCov = Arrays.asList(0.001d, 0d, 0d, 0d, 0.001d, 0d, 0d, 0d, 0.001d);// TODO Make Parameter
this.imu.setOrientationCovariance(tmpCov);
this.quatTime = sensorEvent.timestamp;
// logger.debug("Sensor rotate value : " + this.imu);
// System.out.println("Sensor rotate value : " + this.imu);
}
}
}
示例2: onSensorChanged
import android.hardware.SensorManager; //导入方法依赖的package包/类
@Override
public void onSensorChanged(SensorEvent event) {
// we received a sensor event. it is a good practice to check
// that we received the proper event
if (event.sensor.getType() == Sensor.TYPE_ROTATION_VECTOR) {
// convert the rotation-vector to a 4x4 matrix. the matrix
// is interpreted by Open GL as the inverse of the
// rotation-vector, which is what we want.
SensorManager.getRotationMatrixFromVector(currentOrientationRotationMatrix.matrix, event.values);
// Get Quaternion
// Calculate angle. Starting with API_18, Android will provide this value as event.values[3], but if not, we have to calculate it manually.
SensorManager.getQuaternionFromVector(temporaryQuaternion, event.values);
currentOrientationQuaternion.setXYZW(temporaryQuaternion[1], temporaryQuaternion[2], temporaryQuaternion[3], -temporaryQuaternion[0]);
}
