Method for performing volumetric reconstruction

Patent, 2024

The present disclosure relates to a method and capturing arrangement for creating a three-dimensional model of a scene. The model comprises a three-dimensional space comprising a plurality of discrete three-dimensional volume elements (V1,1, V1,2) associated with three initial direction-independent color values and an initial opacity value. The method comprises obtaining a plurality of images of said scene and defining a minimization problem. Wherein the minimization problem comprises three residuals, one for each color value, wherein each residual is based on the difference between (a) the color value of each image element of each image and (b) an accumulated direction-independent color value of the volume along each ray path of each image element. The method further comprises creating the three-dimensional model of the scene by solving said minimization problem.
