Method for mapping 2-dimensional point of interest in a 3-dimensional view, comprising: capturing a 3-dimensional image with an augmented reality device by obtaining a 3D representation of the 3D image via 3D-sensors and an image sensor of the augmented reality device, and wherein the 3D representation comprises a 2D frame, the 2D-frame being a 2D-image captured by the image sensor and consisting of points defined by two-dimensional frame coordinates, and wherein each point is associated with a depth captured by the 3D-sensors; matching images of a 2D image database with the captured 3D-image, by comparing each 2D image of the 2D image database with the 2D frame of the 3D representation by scaling and translating the 2D image over the 2D frame; wherein the 2D image database comprises 2-dimensional images associated with points of interest having a 2-dimensional data set; wherein first coordinates of a point of interest are determined in relation to a reference point of the image, the reference point being a point suitable to be taken as an origin for a coordinate system; and when the 2D-image matches the 3D image: capturing 3D-data for the matched 2D-image, by: determining frame coordinates of the reference point of the 2D image in the 2D frame; determining scaling information from the 2D image size and the 2D frame size; converting the 2D-data set of the point-of-interest to a 3D-data set by: applying the scaling information to the coordinates of the point of interest; applying the frame coordinates of the reference point to the first coordinates of the point of interest to obtain frame coordinates of the point of interest; and determining a depth-coordinate for the point of interest from the depth associated with the frame coordinates of the point interest and the scaling information, acquiring global position coordinates of the augmented reality device using an absolute positioning sensor; and storing the point of interest with the global position coordinates of the augmented reality device. capturing a 3-dimensional image with an augmented reality device by obtaining a 3D representation of the 3D image via 3D-sensors and an image sensor of the augmented reality device, and wherein the 3D representation comprises a 2D frame, the 2D-frame being a 2D-image captured by the image sensor and consisting of points defined by two-dimensional frame coordinates, and wherein each point is associated with a depth captured by the 3D-sensors;
