1. A computer-implemented method for dynamically generating a three-dimensional (3D) scene, comprising: acquiring a red green blue (RGB) image of the 3D scene, wherein the RGB image is in RGB color space; converting the RGB image from RGB color space to a luminance (Y) and chrominance (UV) image in YUV color space comprising luminance (Y) information and UV information; acquiring reflectance information of the 3D scene from a laser scanner; based on a blending function, blending the luminance information with the reflectance information resulting in a blended YUV image, wherein the blending function provides for completely replacing the luminance information with the reflectance information; converting the blended YUV image from YUV color space into RGB color space resulting in a blended RGB image; and outputting the blended RGB image.
