Motion analysis module: 3D posture analysis
The 3D posture analysis presents more detailed posture values. In contrast to the
2D posture analysis, three cameras are needed
to capture the body postures. So the human posture is captured and analysed synchronously
from three perspectives.
In order to not get just a snapshot of the posture, the patient is captured three
times with a rotation of 45 degrees each.

3D posture analysis has less requirements for the needed space to be set up compared
to the previous one.
It is only a space of 1 x 2,5m needed. Due to the V-form of the new camera stand,
the cameras enable a precise 3D reconstruction of all body axes, which is easily
performed, aided by the semi-automatic marker detection algorithm.
The camera stand can be mounted either on the wall or on a tripod or on a solid
bar with floorplate. The background panel is very useful for calibration when 2D
posture analysis is done.

Calibration
To perform a 3D posture analysis, a calibration of the measuring spot is necessary.
This can be automatically done with the help of a calibration frame, especially
designed by CONTEMPLAS for this purpose. This calibration frame allows an exact
calibration (with an accuracy of up to 1/10th millimeter). Once the calibration
is done, you can analyse patients until you change the camera position or the zoom
factor.

Analysis and results
In the analysis protocol, additional body points are integrated into the calculation
of the measuring results in order to calculate the body rotations. The acquisition
of the body points can be done manually or as far as possible automatically.
Additionally to all results of the 2D posture analysis, the 3D posture analysis
provides the calculation of pelvic rotations and shoulder rotations. These two values,
which cannot be measured by 2D posture analysis, provide important information which
may be essential for the treatment of the defective postures. It goes without saying,
that all quantitative and qualitative measuring tools are available for an optimal
visualization.
Report
Similar to the report generated when you perform a 2D posture analysis, all measured
results are automatically illustrated and displayed. You can freely combine your
individual report pages with the automatic report pages.
