Patent Images

1. A method of processing image data defining a plurality of sequences of images, each from a respective camera, of a plurality of objects moving in a scene to produce signals defining representations of the objects in a three-dimensional computer model, the method comprising the steps of:

  • processing image data from a first of the cameras to identify image data relating to objects in the scene;

    processing image data from a second of the cameras to identify image data relating to objects in the scene;

    processing the identified image data from the first camera for each object to define an object representation in the three-dimensional computer model having a height dependent upon the image data for the object from the first camera;

    processing the identified image data from the second camera for each object to define an object representation in the three-dimensional computer model having a height dependent upon the image data for the object from the second camera;

    comparing the height of the representation of each object generated in dependence upon image data from the first camera with the height of the representation of the corresponding object generated in dependence upon image data from the second camera; and

    generating object representations in the three-dimensional computer model in dependence upon the height comparisons, wherein, when the heights of the corresponding representations are not within a predetermined amount of each other, the taller representation is split into a first portion having a height corresponding to the height of the smaller representation and a second portion comprising the remaining part of the taller representation, and wherein a further representation is defined in the three-dimensional model by re-positioning the second portion in the three-dimensional model.
