Description: |
|
This is mounting matrix for motion sensors. Mounting matrix |
|
is a 3x3 unitary matrix. A typical mounting matrix would look like |
|
[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be |
|
easy to tell the relative positions among sensors as well as their |
|
positions relative to the board that holds these sensors. Identity matrix |
|
[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly |
|
aligned with each other. All axes are exactly the same.
