Abstract: A film shooting system comprises: a camera; a sensor system comprising a first optical sensor system comprising one optical sensor and suitable for recording data in an optical mode, and a second sensor system comprising one sensor, suitable for recording data; a computerised tracking module suitable for incorporating the data from one sensor from the first system and from one sensor from the second system, and for determining location data of the camera from this data; a computerised combination module, suitable for repeatedly determining location data of the camera from both the location data determined in the optical mode and in the second mode.
