1. System for filming video footage in a real space defined in a real reference system, wherein the system for filming video footage comprises:
a filming camera, suitable for recording a real image for a plurality of discrete time frames, a location pinpointing system, comprising:
at least one sensor, provided with location data relative to the filming camera that are known for each time frame, and suitable for transmitting to a computerized pinpointing module the natural topographical information detected by the sensor,a computerized pinpointing module suitable for determining, for each time frame, the filming camera location data in the real reference system based on location data of the sensor, and on a comparison of the natural topographical information and a predetermined three-dimensional model of the real space, a monitoring screen, a computerized compositing module suitable for generating on the monitoring screen, for each time frame, a composite image of the real image and of a projection of a virtual image taken from a database of virtual animations, said projection generated according to the filming camera location data in the real reference system. |
