There is provided a method for creating a voxel occupancy model. The voxel occupancy model is representative of a region of space which can be described using a three-dimensional voxel array. The region of space contains at least part of an object. The method comprises receiving first image data, the first image data being representative of a first view of the at least part of an object and comprising first image location data, and receiving second image data, the second image data being representative of a second view of the at least part of an object and comprising second image location data. The method also comprises determining a first descriptor, the first descriptor describing a property of a projection of a first voxel of the voxel array in the first image data, and determining a second descriptor, the second descriptor describing a property of a projection of the first voxel in the second image data. The method also comprises assigning an occupancy value to the first voxel based on the first and second descriptors, the occupancy value being representative of whether the first voxel is occupied by the at least part of an object.
