Modeling three-dimensional interiors from photographic images, and applications thereof

A system comprising:

• at least one processor;
• an interior floor plan module configured to be executed on the at least one processor and that receives input data from a user specifying a floor plan of the interior of the building;
• a user constraint input module configured to be executed on the at least one processor and that displays a three-dimensional model of an interior of a building, receives a first constraint input by a user indicating that a position on the floor plan corresponds to a position on the displayed three-dimensional model, and receives a second constraint input by a user indicating that a position on a photographic image of the interior corresponds to a position on the displayed three-dimensional model, wherein a camera took the photographic image of the interior;
• and
• a photogrammetry module configured to be executed on the at least one processor and that locks a first geometric parameter associated with the three-dimensional model based at least in part on the first constraint input by the user or a first camera parameter associated with the camera as a locked parameter based at least in part on the second constraint input by the user and alters a second geometric camera parameter associated with the three-dimensional model or a second camera parameter associated with the camera based on the first and second constraints and the locked parameter.

A computer program product comprising a non-transitory computer readable medium having control logic stored therein for causing a computer to perform a method comprising:

• displaying a three-dimensional model of an interior of a building;
• receiving input data from a user specifying a floor plan of the interior of the building;
• receiving a first constraint input by a user indicating that a position on the floor plan corresponds to a position on the displayed three-dimensional model;
• receiving a second constraint input by a user indicating that a position on a photographic image of the interior corresponds to a position on the displayed three-dimensional model, wherein a camera took the photographic. Image of the interior;
• locking a first geometric parameter associated with the three-dimensional model based at least in part on the first constraint input by the user or a first camera parameter associated with the camera as a locked parameter based a least in part on the second constraint input by the user and
• altering a second geometric parameter associated with the three-dimensional model or a second camera parameter associated with the camera based on the first and second constraints and the locked parameter.
