Reference Surface Detection for Mobile Dimensioning

Abstract:

A method includes: obtaining a reference stereo image from a stereo camera assembly of a mobile computing device; detecting a reference surface from the reference stereo image; determining an inclination angle of the reference surface relative to an output vector of an auxiliary sensor of the mobile computing device; obtaining a first dimensioning stereo image from the stereo camera assembly; detecting the reference surface in the first dimensioning stereo image based on the inclination angle; detecting a first object surface in the first dimensioning stereo image; and generating dimensions of the object based on the first object surface and the reference surface.
