Systems and methods for pitch determination

A system comprising:

• one or more processors;
• and
• non-transitory computer-readable media storing instructions which, when executed by the one or more processors, cause the one or more processors to:
• obtain an image depicting a structure, the image being captured via a user device positioned proximate to the structure;
• segment the image to identify, at least, an eave vector and a rake vector which are associated with a roof facet of the structure;
• adjust the eave vector and rake vector with a mutual transform to produce a perpendicular angle between the eave vector and rake vector;
• calculate a cross product vector based on the transformed eave vector and the rake vector;
• and
• extract a normal vector of the roof facet based on an inverse of the mutual transform being applied to the cross product vector.

A non-transitory computer storage media storing instructions that when executed by a system of one or more processors, cause the one or more processors to perform operations comprising:

• obtaining an image depicting a structure, the image being captured via a user device positioned proximate to the structure;
• segmenting the image to identify, at least, an eave vector and a rake vector which are associated with a roof facet of the structure;
• adjusting the eave vector and rake vector with a mutual transform to produce a perpendicular angle between the eave vector and rake vector;
• calculating a cross product vector based on the transformed eave vector and the rake vector;
• and
• extracting a normal vector of the roof facet based on an inverse of the mutual transform being applied to the cross product vector.
