Coordinates re-calculation

In some cases you may need to re-calculate the coordinate system in your code. For example, when Artec scanner is mounted on robotic arm, you may want to use coordinates of tripod mounting instead of the position of the main camera.

This article contains brief information about coordinates re-calculation, more comprehensive workflow as well as texture coordinates re-calculation is described here in Artec SDK documentation (navigate to the section "Coordinates and Transformation Matrices").

 

Artec Eva

(1) the center of the main camera of Artec Eva
(2) tripod mounting point

To recalculate (1) to (2), please use this matrix with coordinates:
1           0              0             0
0           0.983      -0.186     44.633
0           0.186       0.983     -27.776
0           0              0             1

 

Artec Spider/Space Spider

(1) the center of the main camera of Artec Spider/Space Spider
(2) tripod mounting point

To recalculate (1) to (2), please use this matrix with coordinates:
-1    0                  0                 0
0     0.954709     0.297542    120.97
0     0.297542    -0.954709    16.053
0     0                  0                  1
