Apparatus for real-time 3D capture
First Claim
1. A real-time 3D capture system for a mobile electronic device having a camera, the capture system comprising:
- an infrared projector that projects a pattern onto an imaging target;
an infrared sensor that captures the pattern;
a control module that controls the projector and sensor, takes data from the sensor, determines depth information from the data, and transmits the depth information to the mobile electronic device;
a battery that provides power to the projector, sensor, and control module;
a software module connected to the mobile electronic device that controls communication between the control module and the mobile electronic device, wherein communication comprises data from the camera and the depth information;
wherein the software module further comprises a calibration module that enables correction for rotation and translation of the infrared sensor relative to the camera for registering the depth information with the output from the camera;
a mounting bracket that removably couples the capture system to the mobile electronic device such that the capture system when coupled maintains alignment with the camera; and
a chassis that holds the projector, sensor, control module, and battery, and couples to the mounting bracket, wherein the projector, sensor, and control module are fixed to the chassis.
