Abstract: A method and system for 3D modeling of a construction or structure based on producing a 3D image from digital 2D images of the construction or structure, transforming the 3D image to a data point cloud presentation, electing a collection of data points, identifying an object of the construction or structure that matches the collection of data points, attaching corresponding visual images to a record of the identified object and repeating these steps for any collection of data points until completing the construction of a 3D model based on a combination of all identified objects. This 3D modeling is based on photos obtained from digital photographing means mounted on a UAV (Unmanned Aerial Vehicle) and launched to survey the construction or structure.
