Abstract
An image processing method includes generating an initial representation of a three-dimensional environment using a three-dimensional array of elements having a first spatial resolution with respect to the three-dimensional environment; generating a distance field, DF, representation from the initial representation, the DF representation including a three-dimensional array of distance values having a second spatial resolution with respect to the three-dimensional environment; and applying a data compression process to the DF representation to generate a data-compressed DF representation.

An image processing method comprising:
- generating an initial representation of a three-dimensional environment using a three-dimensional array of elements having a first spatial resolution with respect to the three-dimensional environment;
- generating a distance field, DF, representation from the initial representation, the DF representation comprising a three-dimensional array of distance values having a second spatial resolution with respect to the three-dimensional environment;
- and
- applying a data compression process to the DF representation to generate a data-compressed DF representation,
- wherein the first spatial resolution is a measure of a distance between adjacent points in the three dimensional array of elements, and
- wherein the second spatial resolution is a measure of a distance between adjacent points in the three-dimensional array of distance values.
A non-transitory, machine readable storage medium which stores computer software which, when executed by a computer, causes the computer to perform a method for:
- generating an initial representation of a three-dimensional environment using a three-dimensional array of elements having a first spatial resolution with respect to the three-dimensional environment;
- generating a distance field, DF, representation from the initial representation, the DF representation comprising a three-dimensional array of distance values having a second spatial resolution with respect to the three-dimensional environment;
- and
- applying a data compression process to the DF representation to generate a data-compressed DF representation,
- wherein the first spatial resolution is a measure of a distance between adjacent points in the three dimensional array of elements, and
- wherein the second spatial resolution is a measure of a distance between adjacent points in the three-dimensional array of distance values.
Image processing apparatus comprising:
- a processor configured to generate an initial representation of a three-dimensional environment using a three-dimensional array of elements having a first spatial resolution with respect to the three-dimensional environment;
- a distance field, DF, representation generator configured to generate an DF representation from the initial representation, the DF representation comprising a three-dimensional array of distance values having a second spatial resolution with respect to the three-dimensional environment;
- and
- a data compressor configured to apply a data compression process to the DF representation to generate a data-compressed DF representation,
- wherein the first spatial resolution is a measure of a distance between adjacent points in the three dimensional array of elements, and
- wherein the second spatial resolution is a measure of a distance between adjacent points in the three-dimensional array of distance values.
