Abstract: Methods, systems and apparatuses may provide for technology that obtains multi-camera video data including a first 2D image corresponding to a first camera and a second 2D image corresponding to a second camera. The technology may also identify an association between a first instance of a 3D object in the first 2D image and a second instance of the 3D object in the second 2D image, and automatically generate a 3D bounding box around the 3D object based on the association between the first instance and the second instance.

Abstract: Methods and apparatus to detect collision of a virtual camera with objects in a three-dimensional volumetric model are disclosed herein. An example virtual camera system disclosed herein includes cameras to obtain images of a scene in an environment. The example virtual camera system also includes a virtual camera generator to create a 3D volumetric model of the scene based on the images, identify a 3D location of a virtual camera to be disposed in the 3D volumetric model, and detect whether a collision occurs between the virtual camera and one or more objects in the 3D volumetric model.
