Method and system for texturing an image

A system for rendering an image of a 3D environment, the system comprising:

• a processor;
• and
• a non-transitory computer readable storage medium comprising instructions stored thereon;
• the processor, upon execution of the instructions, being configured for:
• receiving a plurality of reference images, each reference image representing a respective view of the 3D environment according to a respective reference viewpoint position within the 3D environment, each reference image comprising a respective plurality of reference pixels having a respective reference texture value associated thereto;
• generating, using a 3D model representative of the 3D environment, a pre-image of the 3D environment according to a given position within the 3D environment, a given direction and a given field of view, the pre-image comprising a plurality of given pixels having no texture value assigned thereto and each given pixel encompassing a respective portion of the 3D model;
• for each given pixel:
• identifying, amongst the reference viewpoint positions, an adequate viewpoint position for the given pixel;
• identifying a given one of the reference images of which the respective reference viewpoint position matches the adequate viewpoint position and for which a given one of the reference pixels encompasses the respective portion of the 3D model;
• and
• assigning a given texture value to the given pixel based on the respective reference texture value associated with the given one of the reference pixels, thereby texturing the pre-image and obtaining a rendered image;
• and
• outputting the rendered image.
