Abstract

System for filming a video movie in a real space comprising: —a filming camera (9), —a sensor (16), —a computerized pinpointing module (27) for determining the location of the filming camera, —a monitoring screen (15), —a computerized compositing module (32) for generating on the monitoring screen (15) a composite image of the real image and of a projection of a virtual image, generated according to the filming camera (9) location data.

Claims

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 of the real space detected by the sensor,

a second sensor suitable for transmitting to said computerized pinpointing module natural topographical information of the real space detected by said second sensor, and having at least one characteristic that is different from the first sensor, chosen from among the position, the orientation, the solid angle of view, the acquisition frequency, the optical axis, and the field of view,

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.
