Abstract

A real time 3D survey site modeler is disclosed. One embodiment includes a survey data collector to collect survey data for a location and obtain information for each object that is surveyed. In addition, a 3D model creator receives the collected survey data and creates a 3D model of the world being surveyed in real time.

First claim

What is claimed is:

1. A method for real-time 3D map generation during a survey, the method comprising:
accessing a 3D model of an area to be surveyed by a plurality of different survey devices operating within the area to be surveyed, wherein the 3D model of the area is generated from at least one of an aerial map, a topographical map, a terrain map, a physical map, a road map, or as satellite map;
selecting, by one of the plurality of different survey devices, an object located within the area to be surveyed;
determining, by the one of the plurality of different survey devices, a location of the object;
defining, by the one of the plurality of different survey devices, attributes of the object, the attributes including a size of the object and the location of the object;
utilizing, by the one of the plurality of different survey devices, a wire frame to represent the object in the 3D model; thereafter
associating, by the one of the one plurality of different survey devices, the attributes of the object with the wire frame representation of the object in the 3D model;
draping, by the one of the plurality of different survey devices, imagery of the object over the wire frame of the object to form a 3D image of the object within the 3D model, the imagery generated from one or more images of the object by scaling the one or more images based on the attributes of the object;
updating the 3D model on each of the plurality of different survey devices operating within the area to include the 3D image of the object;
comparing, by the one of the plurality of different survey devices, attributes of the object with intended design information to determine whether differences are within predetermined design tolerances; and
providing an output if the differences are not within the predetermined design tolerances.

2. The method of claim 1 wherein the attributes of the object are selected from the group consisting of: location, height, width, depth, material type(s), physical description, and scientific name.

3. A 3D survey site modeling system stored on a non-transitory computer-readable storage medium, the system comprising:
a survey data collector to collect survey data for each object that is surveyed, the survey data including a size of each object and a location of each object; and
a 3D model creator to receive the collected survey data and create a 3D model of the location being surveyed in real time, where a creation of the 3D model is done in a cloud allowing visualization of the model both in a field environment and in an office setting during a survey process, wherein for each object the creation comprises:
utilizing a wire frame to represent the object in the 3D model; and
draping imagery of the object over the wireframe of the object to form a 3D image of the object, the imagery generated from one or more images of the object by scaling the one or more images based on the attributes of the object;

a real-time comparator to compare the 3D model of the location being surveyed with intended design information for the location to determine whether differences are within predetermined design tolerances and provide an output if the differences are not within the predetermined design tolerances.

4. The 3D survey site modeling system of claim 3 further comprising:
a draped image creator to use the information for each object to select a 3D representation of the object from a 3D model database.

5. The 3D survey site modeling system of claim 3 further comprising:
a photogramatic processing module to incorporate an image of the object with a 3D representation of the object selected from a 3D imagery database and to incorporate the 3D representation of the object into the 3D model of the location being surveyed.

6. The 3D survey site modeling system of claim 3 where the objects are sized and dimensioned based on one or more measurement taken to the object in the field.

7. The 3D survey site modeling system of claim 3 where imagery collected in the survey process is draped onto the model.

8. A non-transitory computer-readable storage medium comprising computer executable code for directing a processor to execute a method for real-time 3D map generation during a survey, the method comprising:
accessing a 3D model of an area to be surveyed by a plurality of different survey devices operating within the area to be surveyed, wherein the 3D model of the area is generated from at least one of an aerial map, a topographical map, a terrain map, a physical map, a road map, or a satellite map;
selecting, by one of the plurality of different survey devices, an object located within the area to be surveyed;
determining, by the one of the plurality of different survey devices, a location of the object;
determining, by the one of the plurality of different survey devices, attributes of the, the attributes including a size of the object and the location of the object;
utilizing, by the one of the plurality of different survey devices, a wire frame representation of the object to the 3D model; thereafter
associating, by the one of the plurality of different survey devices, the attributes of the object with the wire frame representation of the object in the 3D model;
draping, by the one of the plurality of different survey devices, imagery of the object over the wire frame of the object to form a 3D image of the object within the 3D model, the imagery generated from one or more images of the object by scaling the one or more images based on the attributes of the object;
updating the 3D model on each of the plurality of different survey devices operating within the area to include the 3D image of the object;
comparing, by the one of the plurality of different survey devices, attributes of the object with intended design information to determine whether differences are within predetermined design tolerances; and
providing an output if the differences are not within the predetermined design tolerances.

9. The non-transitory computer-readable storage medium recited of claim 8 wherein the attributes of the object are selected from the group consisting of: location, height, width, depth, material type(s), physical description, and scientific name.
