What is Project Tango?

Project Tango is a platform that uses computer vision to give devices the ability to understand their position relative to the world around them.

Human-scale understanding of space and motion

Source: Google Developers

A Brief Description

A project from Google ATAP

Runs on standalone devicesSmartphones and tablets

Determines devices position and orientation within the environment


Technologies Used

SLAM (Simultaneous Localization and Mapping)

Virtual reality

Augmented display

3D mapping

How It works?

Hardware componentsRGB camera

Depth-sensing camera

Fisheye Camera (180 field of view)

Sensors (Gyrometer, accelerometer, IR, etc.)

Computer vision processors

How It Works?

IR emits infrared light

Sensor detects the depth

RGB camera captures regular images.

Uses sensors to recognize position and orientation of device

Combines the information from all devices to create 3D mapping of the environment

Features

3D motion and feature trackingTrack position and orientation

Gives real-time information of 3D motion
