Abstract
A radio transceiver included in or attached to an imaging camera is used to facilitate the automatic determination of a scale factor in a three-dimensional (3D) reconstruction. The radio transceiver transmits a radio signal from each of one or more camera positions and measures a reflection profile for the transmitted signal. The measured reflection profile is compared to a simulated reflection profile, generated from a 3D model of the subject/scene of interest, to determine an estimate of an unknown scale for the 3D model. In various embodiments, the radio transceiver may be adapted from a radio device that already exists in or on the imaging camera (e.g., a cellular radio, Bluetooth® radio, or the like) or may be added to an imaging camera.
