摘要： Methods, computer programs, and computer systems facilitate deriving three-dimensional measurement information and/or creating three-dimensional models and maps, from single images of three-dimensional objects. Aspects of the invention include obtaining at least one two-dimensional single image of the object, deriving three-dimensional coordinate information associated with the image, and obtaining three-dimensional measurements based on projection and/or shadow measurements of the object and metadata derived from the single image. In another aspect of the method, the method includes the further step of creating three-dimensional models or maps based on the projection and/or shadow measurements.

摘要： A method for deriving three-dimensional measurement information and/or creating three-dimensional models and maps, from single images of at least one three-dimensional object is provided. The method includes the steps of: (a) obtaining at least one two-dimensional single image of the object, the image consisting of image data and being associated with an image geometry model (IGM); (b) deriving three-dimensional coordinate information associated with the image, based on the IGM, and associating the three-dimensional coordinate information with the image data; (c) analyzing the image data so as to: (i) measure the projection of the object using the IGM to derive measurement data including the height and/or point-to-point distances pertaining to the object; and/or (ii) measure the shadow of the object to derive measurement data including the height and/or point-to-point distance pertaining to the object; and (d) obtaining three-dimensional measurements based on the projection and/or shadow measurements of the object. In another aspect of the method, the method includes the further step of creating three-dimensional models or maps based on the projection and/or shadow measurements. A series of algorithms are also provided for processing the method of the invention. A computer system and related computer program for deriving three-dimensional measurement information and/or creating three-dimensional models and maps, from single images of at least one three-dimensional object is provided based on the disclosed method is also provided.
