Abstract

Systems and methods are disclosed for adjusting plane positions in multi-dimensional models. Disclosed is moving a plane associated with an architectural element based on a scale and a translation positional error, wherein the scaled is determined based on the architectural element, and the translation position error is based on a position of the architectural element, and reconstructing the multi-dimensional building model based on the moved plane.

First claim

1 .- 19 . (canceled)

20 . A method of scaling a three-dimensional (3D) scene, the method comprising:
receiving a plurality of images comprising a building object; extracting a plurality of lines of a non-architectural element in at least one image of the plurality of images; extracting at least one dimension associated with the non-architectural element based on the plurality of lines of the non-architectural element; generating a 3D model based on the at least one dimension associated with the non-architectural element.

21 . The method of claim 20 , wherein the plurality of lines comprise a plurality of boundaries.

22 . The method of claim 20 , wherein extracting the plurality of lines of the non-architectural element comprises receiving identifications of the plurality of lines of the non-architectural element.

23 . The method of claim 20 , wherein extracting the at least one dimension associated with the non-architectural element comprises:
extracting a dimensional ratio associated with the non-architectural element; and comparing the dimensional ratio associated with the non-architectural element to known dimensional ratios of industry standard non-architectural elements.

24 . The method of claim 23 , wherein comparing the dimensional ratio associated with the non-architectural element to known dimensional ratios of industry standard non-architectural elements is based on a closest dimensional ratio.

25 . The method of claim 23 , wherein comparing the dimensional ratio associated with the non-architectural element to known dimensional ratios of industry standard non-architectural elements is based on a threshold ratio.

26 . The method of claim 25 , wherein the threshold ratio is ten percent.

27 . The method of claim 20 , further comprising extracting an architectural element proximate to the non-architectural element.

28 . The method of claim 20 , wherein generating the 3D model comprises generating a 3D model of the building object.

29 . One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform a method of scaling a three-dimensional (3D) scene, the method comprising:
receiving a plurality of images comprising a building object; extracting a plurality of lines of a non-architectural element in at least one image of the plurality of images; extracting at least one dimension associated with the non-architectural element based on the plurality of lines of the non-architectural element; generating a 3D model based on the at least one dimension associated with the non-architectural element.

30 . The non-transitory computer-readable media of claim 29 , wherein the non-architectural element includes any of: lamp posts or telephone poles.

31 . The non-transitory computer-readable media of claim 29 , wherein the non-architectural element includes any of: automobiles or stop signs.

32 . The non-transitory computer-readable media of claim 29 , wherein the plurality of lines comprise a plurality of boundaries.

33 . The non-transitory computer-readable media of claim 29 , wherein extracting the plurality of lines of the non-architectural element comprises receiving identifications of the plurality of lines of the non-architectural element.

34 . The non-transitory computer-readable media of claim 29 , wherein extracting the at least one dimension associated with the non-architectural element comprises:
extracting a dimensional ratio associated with the non-architectural element; and comparing the dimensional ratio associated with the non-architectural element to known dimensional ratios of industry standard non-architectural elements.

35 . The non-transitory computer-readable media of claim 34 , wherein comparing the dimensional ratio associated with the non-architectural element to known dimensional ratios of industry standard non-architectural elements is based on a closest dimensional ratio.

36 . The non-transitory computer-readable media of claim 34 , wherein comparing the dimensional ratio associated with the non-architectural element to known dimensional ratios of industry standard non-architectural elements is based on a threshold ratio.

37 . The non-transitory computer-readable media of claim 36 , wherein the threshold ratio is ten percent.

38 . The non-transitory computer-readable media of claim 29 , further comprising extracting an architectural element proximate to the non-architectural element.

39 . The non-transitory computer-readable media of claim 29 , wherein generating the 3D model comprises generating a 3D model of the building object.
