Enabling use of three-dimensonal locations of features with two-dimensional images

A computer-readable storage disk or storage device comprising instructions that, when executed, cause at least one processor to at least:

• access an image from a set of images, the image of an environment having a set of features;
• access metadata associated with the image to identify the set of features, the metadata including a set of three-dimensional (3D) locations of the features and a set of two-dimensional (2D) locations of the features, the 3D locations and the 2D locations present in a 3D model, the 3D model based on the set of images, the metadata excluding a portion of the 3D model;
• determine a geometric characteristic associated with one or more points in the image using the 3D locations and the 2D locations;
• and
• cause the geometric characteristic to be displayed in a user interface.

An apparatus comprising:

• means for accessing an image from a set of images, the image of an environment having a set of features;
• means for accessing metadata associated with the image to identify the set of features, the metadata including a set of three-dimensional (3D) locations of the features and a set of two-dimensional (2D) locations of the features, the 3D locations and the 2D locations present in a 3D model, the 3D model based on the set of images, the metadata excluding a portion of the 3D model;
• means for determining a geometric characteristic associated with one or more points in the image using the 3D locations and the 2D locations;
• and
• means for causing the geometric characteristic to be displayed in a user interface.
