Abstract
A method of imaging a dental object using a dental camera comprising the steps of: recording a plurality of three-dimensional optical images of a dental object using a dental camera; determining whether an overlapping area, formed by at least a partial overlap of the plurality of three-dimensional optical images, satisfies one or more recording requirements; and generating an acoustic sound during the recording using a sound generator; wherein the sound serves as a feedback for the user and imparts to the user information (i) about the current status of a recording of the images and/or (ii) about recording requirements of the dental camera; wherein a speed of movement of the dental camera relative to the object is determined by (i) using a motion sensor on the dental camera or (ii) by analysis of the measured images; and wherein the acoustic sound is generated as a function of the determined speed of movement.
