Fit prediction based on feature detection in image data

A non-transitory computer-readable medium storing executable instructions that, when executed by at least one processor of a computing device, are configured to cause the at least one processor to:

• generate a three-dimensional model of a nose of a user based on depth data extracted from a correlation of a change in a position and orientation of the computing device with a change in a position of at least one fixed feature between a first image data of the nose of the user and a second image data of the nose of the user, the first image data and the second image data captured by an application executing on the computing device;
• and
• simulate, by a simulation engine accessible to the computing device, a fit of a head mounted wearable device on the user based on the three-dimensional model of the nose of the user;
• wherein the at least one fixed feature includes at least two facial features that are representative of a fixed measurement associated with the nose of the user;
• wherein at least one of the at least two facial features include:
• a sellion at a root end portion of a nasal ridge of the nose;
• a tip of the nose at a distal end portion of the nasal ridge of the nose;
• an ala at a lower end portion of the nose, corresponding to a first lower end portion and a second lower end portion of the nose;
• or
• an inner corner portion of a right eye and an inner corner portion of a left eye of the user.
