Original Abstract Submitted

there is provided techniques for generating a dense 3d point cloud of a scene. a method is performed by an image processing device (). the method comprises performing (s) sequential matching for a set of images, obtained from an image scan of the scene, where each image has a color value and a depth value, to establish a correspondence between consecutive images in the set of images, to generate a sparse 3d point cloud from the images, and to estimate one camera pose value for each image. the method comprises determining (s) one reliability value for each camera pose value. the method comprises generating (s) the dense 3d point cloud, when a lowest value of all determined reliability values is larger than a threshold reliability value, by densification of the sparse 3d point cloud and using the estimated camera pose values.
