Method and system for aligning a digital model of a structure with a video stream

A non-transitory computer-readable storage medium storing a set of instructions that, when executed by one or more computer processors, causes the one or more computer processors to perform operations for aligning a digital model of a structure with a displayed portion of the structure within a video stream captured by a camera device, the operations comprising:

• determining an approximate position of the camera device in the digital model;
• determining a position and an orientation for a plurality of digital surfaces within the digital model visible from the approximate position of the camera device;
• receiving a video stream from the camera device;
• determining a position and an orientation of a plurality of object surfaces visible in the video stream;
• determining a 3D translation, a 3D scale, and a 3D rotation that maximize an alignment of the position and orientation of the plurality of digital surfaces with the position and orientation of the plurality of object surfaces;
• and
• applying the 3D translation, the 3D scale, and the 3D rotation to the digital model and displaying the digital model contemporaneously with a display of the video stream.
