+4_yAxis_rotation_reconstruction.py
+====================================
+Berechnet die Rotationsachse eines Gelenks aus drei Board-Erkennungs-Timestamps.
+
+Gegeben drei Messungen (Pos A, B, C) – in denen dieselben fremd-Marker
+(link != 'Board') erkannt wurden – bestimmt das Skript:
+ - Richtung der Rotationsachse (axisDir, Einheitsvektor)
+ - Referenzpunkt auf der Achse (axisPoint_mm)
+ - Residuen pro Punkt (Qualitätsmass)
+
+Methode (doc/04_y_achse.md):
+ Jeder Marker bewegt sich auf einem Kreisbogen. Die Ebene des Kreises
+ steht senkrecht zur Rotationsachse → Normalenvektor = Achsenrichtung.
+ Der Umkreismittelpunkt des Dreiecks P1-P2-P3 liegt auf der Achse.
+
+ Statt nur dem Marker-Zentrum werden alle vier Ecken (corners_m) verwendet:
+ das liefert 4× mehr Datenpunkte und macht die Schätzung robuster.
+
+Usage:
+ python3 4_yAxis_rotation_reconstruction.py
