10 Mounting matrix
12 The mounting matrix is a device tree property used to orient any device
13 that produce three-dimensional data in relation to the world where it is
16 The purpose of the mounting matrix is to translate the sensor frame of
17 reference into the device frame of reference using a translation matrix as
37 reference. This means that the sensor may be flipped upside-down, left-right,
43 to this world. When using the mounting matrix, the sensor and device orientation
