1. A processor-implemented method for 3-dimensional (3D) model reconstruction, the method comprising:

  • receiving, by a processor-based system, a plurality of static images of a scene, each static image generated by a static camera, the static camera positioned at a fixed location and oriented at a fixed viewing angle;

    receiving, by the processor-based system, a plurality of dynamic images of the scene, each dynamic image generated by a movable camera;

    performing, by the processor-based system, 3D reconstruction of a foreground of the scene, based on the static images;

    performing, by the processor-based system, 3D reconstruction of a background of the scene, based on the static images and the dynamic images; and

    superimposing, by the processor-based system, the reconstructed 3D foreground and 3D background, with alignment based on calibration parameters of the static and movable cameras, to provide a hybrid 3D reconstruction of the scene, the calibration parameters including at least one of focal length of the cameras, principal point of the cameras, rotation matrix of the cameras, and translation vector of the cameras.
