vSLAM

Monokulare, Stereo- und RGB-D-vSLAM (Visual SLAM, visuelle simultane Lokalisierung und Kartierung)

vSLAM (Visual SLAM, visuelle simultane Lokalisierung und Kartierung) ist ein Prozess zur Berechnung der Position und Ausrichtung einer Kamera relativ zur Umgebung, während zugleich die Umgebung kartiert wird. Dieser Prozess verwendet nur visuelle Eingaben der Kamera. Anwendungen für vSLAM umfassen Augmented Reality, Robotik und autonomes Fahren. Weitere Einzelheiten finden Sie unter Implement Visual SLAM in MATLAB.
