US 2017/0324941 A1 · Stereoscopic Imaging Using Mobile Computing Devices Having Front-Facing And Rear-Facing Cameras

Abstract

Stereoscopic imaging is performed using a mobile computing device having front- and rear-facing cameras and mounted on a rotational mechanism. The cameras and rotational mechanism are controlled, e.g., by a downloaded application, to capture images of a room or other environment using both the front- and rear-facing cameras at different pan angle and tilt angle combinations. First and second images of a portion of the room or other environment, captured using the front- and rear-facing cameras, are selected for inclusion in a stereo image pair. Obtained images and corresponding metadata are transferred to a remote system. A structure from motion pipeline is used to generate a three-dimensional model of the room or other environment. Data that enables the mobile computing device to display a three-dimensional model of the room or other environment is received from the remote system and used to display the three-dimensional model.

Dependent claims

For use with a mobile computing device, a method for obtaining stereo image pairs that can be used for generating three-dimensional models of a room or other environment or producing virtual reality (VR) content, wherein the mobile computing device includes a front-facing camera and a back-facing camera and is mounted on a rotational mechanism such that the front- and rear-facing cameras of the mobile computing device are each offset from a center or rotation of the rotational mechanism, the method comprising:

controlling the cameras of the mobile computing device and controlling the rotational mechanism to capture images of the room or other environment using both the front- and rear-facing cameras at each of a plurality of different pan angle and tilt angle combinations, such that images corresponding to different tilt angles are obtained by each of the front- and rear-facing cameras of the mobile computing device at each of a plurality of different pan angles.

One or more processor readable storage devices having instructions encoded thereon which when executed cause one or more processors of a mobile computing device to perform a method for obtaining stereo image pairs that can be used for generating three-dimensional models of a room or other environment or producing virtual reality (VR) content, wherein the mobile computing device includes a front-facing camera and a back-facing camera and is mounted on a rotational mechanism such that the front- and rear-facing cameras of the mobile computing device are each offset from a center or rotation of the rotational mechanism, the method comprising:

controlling the cameras of the mobile computing device and controlling the rotational mechanism to capture images of the room or other environment using both the front- and rear-facing cameras at each of a plurality of different pan angle and tilt angle combinations.

A mobile computing device, comprising:

a display;
a front-facing camera;
a back-facing camera;
and
one or more processors configured to control the cameras of the mobile computing device and control a rotational mechanism to which the mobile computing device is mounted to capture images of a room or other environment using both the front- and rear-facing cameras at each of a plurality of different pan angle and tilt angle combinations, such that images corresponding to different tilt angles are obtained by each of the front- and rear-facing cameras of the mobile computing device at each of a plurality of different pan angles.
