角度框架是对象在 3D 空间中的方向的表示。它通常使用欧拉角或四元数来描述。请参阅 http://en.wikipedia.org/wiki/Euler_angles 和 http://en.wikipedia.org/wiki/quat ERNIons_and_spatial_rotation。

什么是 9轴运动传感器？

9轴运动传感器结合了陀螺仪、加速度计和磁力计传感器数据。生成的角度框架是相对于重力（向下）和北方的。9轴运动传感器目前在嵌入式 MotionApps 平台中不可用。 9轴运动传感器优于 6轴imu的优势在于 9轴运动传感器结果可用于导航和其他需要有关相对于N极的角度信息的应用程序。它还消除了 6轴imu解决方案中可能存在航向漂移。

人体运动传感器是什么？

你指的人体运动传感器是检测人体移动的PIR传感器吗？红外线热释电传感器PIR对于径向移动反应最不敏感,而对于横切方向(即与半径垂直的方向)移动则最为敏感. 世强这边有代理ROHM的红外热释电传感器放大器BD9251FV，有可用于人体检测的红外温度传感器的单点和点阵温度传感器，如MLX90614,MLX90615,MLX90621,MLX90640等。

TDK-invensense的运动传感器输出四元数，什么是四元数？如何使用四元数？

四元数是由一个实数和三个虚数组成的数，q = a + ib + jc + kd 四元数以与角度theta和旋转轴v相关的形式表示旋转框架，其中v是三维单位（长度为1）向量，并且q = sin（theta / 2）+ i * vx * cos（theta /2) + i * vy * cos(theta/2) + k * vz * cos(theta/2) DMP 将 MotionFusion 解决方案计算为四元数，因为他可以最明显的表示物体的运动状态

运动传感器能够识别出来运动的剧烈程度吗？手机好像能够识别出来，跑步、走路、蛙跳等等，这些能够识别出来吗。

您好，运动传感器有很多分类，例如有检测人体运动反映的，有检测机械运动以及其他物体运动的，人们一般泛指的运动传感器是指电子类传感器。运动传感器可以用来测量与运动有关的位置、位移、速度、加速度、振动位移、振幅、波动传播等物理量，广泛应用于教学模拟、科研、航天、遥测、自动化等领域，乃至日常生活中的手机也用上了运动传感器。例如我们选型中可以了解的加速度传感器、三轴传感器、陀螺仪传感器、心率传感器等；具体的你可以参考下罗姆的手册：https://www.sekorm.com/doc/2156515.html，看你需要哪一种传感器，我们再进一步支持

What is a quaternion? How do I use a quaternion?

A quaternion is a number with a real and three imaginary components, q = a + i b + j c + k d. A quaternion represents a rotational frame in a form related to the angle theta and axis v of rotation, where v is a three dimensional unit (length 1) vector, and q = sin (theta / 2) + i * vx * cos(theta/2) + i * vy * cos(theta/2) + k * vz * cos(theta/2) You can easily convert a quaternion to Euler angles or a rotation matrix. http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation The DMP calculates the MotionFusion solution as a quaternion because it is the most efficient representation for mathematical applications.

What is an angular frame ?

An angular frame is a representation of an object’s orientation in 3D space. It is commonly described using euler angles or a quaternion. Please see http://en.wikipedia.org/wiki/Euler_angles, and http://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation. An angular frame does not describe the 3D location of an object, only its rotation relative to a reference. The reference rotation for a 6-axis angular frame is flat and level—that is, the vertical axis of the object is aligned with up/down. The reference rotation for a 9-axis angular frame is flat, level, and north: the vertical axis of the object is aligned up/down, and the forward axis of the object is aligned north/south.

Is the way the sensor fusion works being documented for the user?

The Algorithms for sensor fusion is InvenSense IP, and runs in encrypted form on the DMP or as a binary on the host. Sensor fusion outputs quaternions, which is a 3D representation of the movement of an object in space. As long as the Application is using quaternions, there is no need for the system developer to get burdened with the details of sensor fusion implementation.

What are Euler angles? How do I use Euler angles?

Euler angles are a representation of an angular frame, as are quaternions and rotation matrices. Euler angles are a set of three angles, corresponding to pitch, roll, and yaw. Euler angles may be constructed according to many conventions. The axes of and ordering of ordering of pitch, roll, and yaw vary by convention. The Embedded MotionApps Platform makes Euler angles available in the three most common conventions with MLGetEulerAnglesX, MLGetEulerAnglesY, and MLGetEulerAnglesZ. See the Embedded MotionApps Platform Functional Specification for specific details on the definition of these conventions. Euler angles are not commutative. For any Euler angles A, B, a rotation A followed by B is not (B + A) is necessarily equal a rotation B followed by A (B + A). Because of this algebraic property, Euler angles are often not very useful for signal processing applications. Euler angles suffer from a pair of singularity points at which only two of the three angles are significant. The derivative of the Euler angles is discontinuous at this point. This condition is often called gimbal lock.

What does the hardware do and what does the BSP do? Does the hardware without any additional mcu have the quaternion 6 dof fusion output? Is there any hardware that can combine a compass in the attitude results?

The motion algorithms has two major components to it, sensor fusion and calibration. Sensor fusion runs on the DMP (in hardware), while calibration runs on the micro. The hardware sensors (Gyro, and Accel) detect motion, while the BSP has manages the I2c, Timer, and Non volatile memory interfaces. The hardware does perform 6-axis (dof) sensor fusion through the dedicated DMP computation engine. The next release of Embedded MPL software will enable 9-axis sensor fusion that runs in a fully self contained fashion on the DMP. Currently the DMP does not support 9-axis sensor fusion due to a degraded performance. We are planning to eventually push full 9-axis operation to the DMP. 10 axis (altitude) sensor fusions can be performed on the MCU by taking the 9-axis sensor fusion results from hardware, and combining with altitude information from a pressure sensor.
