Reference design aimed at Project Tango

Inuitive, a developer of 3D computer vision and image processing devices, has unveiled a reference design geared for Google's Project Tango, which the company describes as a compact sized module, harnessing Inuitive's NU3000 to serve as the processing engine for 3D sensing and smart sensor hub in Project Tango.


The NU3000 is a multi-core processor, capable of extracting real time depth from stereo, as well as process the depth images (together with other sensors) to fuse a real time localisation and mapping solution. The reference design module contains two cameras arranged in a stereoscopic setting, a fish-eye camera for 2D wide-angle imaging and an inertial motion unit. Thus, Inuitive offers a complete solution that covers both real time depth sensing and smart sensor hub functionalities, to calculate localisation and mapping information, stated the company.

Google recently released a Project Tango Tablet Development Kit, in the form of a 7in tablet. This platform is mostly aimed at developers, to allow developing applications for Tango systems.

NU3000 architecture

The NU3000 can interface and manage three cameras: two as a stereo depth source and one as an RGB sensor. Moreover, it can process all three video streams in real time, to generate a high quality depth image from the stereo, assign colour to the depth images, and execute high-level processing on all available video streams. The NU3000 architecture is combining dedicated hardware accelerators with vector DSPs to allow a power efficient execution of depth sensing as well as higher-level algorithms and applications. It can manage, synchronise, time stamp various sensors. Moreover, it can execute real-time simultaneous localisation and mapping algorithms.

NU3000 architecture

Accordingly, in a Project Tango environment, the NU3000 can serve as the core depth generating engine, together with a smart sensor hub and serve as the primary processor of the mapping and localisation algorithms.
