Labbook IMAV

Installed the Cullmann Revomax RB5.1 ball heads behind the Optitrack cameras. This ball head had a 3/8" screw on the background, so I bought at the Haarlemerdijk four inserts (converting from 3/8" to 1/4").
Performed a calibration. Enough samples where acquired (> 1000 for each camera), which resulted in a Overall Wand Error of 0.182 mm (exceptional). This corresponds with a Overall Mean 3D error of 0.503 mm (2D 0.133 pixels):
Used the triangle on the middle of the soccer field to define the ground plane. Had to rotate over the x-axis over 180 degrees to get the orientation right. Rotated around the y-axis in steps of 10 and 1 degrees until the cameras where in line. Saved the calibration under the name "6 tilted cams":

Installed Motive 1.7.5 and downloaded the Camera SDK 1.7.5.
I ordered connection pieces with a hole for a 1/4" and a 10 mm screw, so that I count mount them on the railing (note the curtains!).
One camera is visible in the Calibration view:
The other cameras are taken by Ruben to the GameLab.
