Mounting matrix 8*4882a593Smuzhiyun is a 3x3 unitary matrix. A typical mounting matrix would look like 9*4882a593Smuzhiyun [0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be 10*4882a593Smuzhiyun easy to tell the relative positions among sensors as well as their 11*4882a593Smuzhiyun positions relative to the board that holds these sensors. Identity matrix 12*4882a593Smuzhiyun [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly 13*4882a593Smuzhiyun aligned with each other. All axes are exactly the same. 14
