WebFeb 12, 2024 · Local motion signals are determined through a technique called Structure-from-Motion (SfM) in which the camera is fixed and the target rotates or the camera moves around the fixed target (Schonberger and Frahm 2016). Local motion signals are, therefore, used to determine and calibrate the object points’ spatial position that will shape the model.
