Scan plaster

Make sure that you have started the module either by clicking on GP GipsScan on the GP Manager start page or by selecting the correct measurement method in the GP FootMess module.

Position the Kinect so that it is not exposed to direct sunlight or light. In order to obtain accurate measurements, the area in front of the Kinect should be free of obstructions at a distance of 1.50 metres.

1. Place the turntable on an elevation of approx. 70 cm and fix the plaster on the turntable with the heel facing downwards. Ensure that the plaster cast is aligned at a 45 - 60° angle on the turntable. The camera should be slightly higher than the plaster cast (see Figure 9).

2. The space behind the plaster should be free of other objects at a distance of 90-110 cm. Other objects could obstruct the measurements.
3. Fix the camera on a tripod or wall mount so that the plantar side of the plaster is centred.
4. Then click on "Scan page" and create a new measurement.

5. The live image window of the 3D scanner opens. (see Figure 10)
6. The measurement process can be actively started by clicking on the "Repeat" button. Start the measurement process when the plantar side of the plaster is facing the camera.
7. After 1-2 rotations, you can end the measurement by pressing the "Ctrl" Press the button.
8. A second window opens. Here you can use the red dots to position the foot vertically and horizontally (see Figure 11).

9. You can define the cutting lines in the following window. Make sure that the upper red line is not higher than required for the later dafo. You can also specify the material thickness here. If you want to use the scan to construct a moulding, we recommend that you make an entry here. The material thickness is subtracted from the scan so that it is not displayed in the design in CAD.
