Data processing

A method comprising:

• capturing successive images using a plurality of cameras arranged according to a predetermined configuration and each having a coordinate system;
• detecting a current location of one or more elements in the captured images with respect to the coordinate system of a camera;
• generating a common camera coordinate system in dependence upon the respective coordinate systems of the plurality of cameras, comprising generating the common camera coordinate system to comprise a generated set of locations including a three-dimensional array of evenly or non-evenly spaced locations in a three-dimensional space included within a field of view of the plurality of cameras, each location of the set of locations having an associated entry that is empty;
• detecting a current location of a given element with respect to the common camera coordinate system based on images captured by the plurality of cameras;
• for each camera:
• generating, in response to detecting that the current location of the given element corresponds to a location in the set of locations of the common camera coordinate system, first data for that location in the set of locations indicative of a mapping between the coordinate system for the camera and the common camera coordinate system and populating an associated entry for that location with the first data;
• and
• generating, in response to a detection of a location in the set of locations for which the first data is indicative of the mapping for two or more cameras with respect to the common camera coordinate system, second data for that location indicative of a mapping between the coordinate systems for the two or more cameras and populating an associated entry for that location with the second data.

A non-transitory, computer readable storage medium containing computer software which, when executed by a computer, causes the computer to perform a method, comprising:

• capturing successive images using a plurality of cameras arranged according to a predetermined configuration and each having a coordinate system;
• detecting a current location of one or more elements in the captured images with respect to the coordinate system of a camera;
• generating a common camera coordinate system in dependence upon the respective coordinate systems of the plurality of cameras, comprising generating the common camera coordinate system to comprise a generated set of locations including a three-dimensional array of evenly or non-evenly spaced locations in a three-dimensional space included within the field of view of the plurality of cameras, each location of the set of locations having an associated entry that is empty;
• detecting a current location of a given element with respect to the common camera coordinate system based on images captured by the plurality of cameras;
• for each camera:
• generating, in response to detecting that the current location of the given element corresponds to a location in the set of locations of the common camera coordinate system, first data for that location in the set of locations indicative of a mapping between the coordinate system for the camera and the common camera coordinate system and populating an associated entry for that location with the first data;
• and
• generating, in response to a detection of a location in the set of locations for which the first data is indicative of the mapping for two or more cameras with respect to the common camera coordinate system, second data for that location indicative of a mapping between the coordinate systems for the two or more cameras and populating an associated entry for that location with the second data.
