Motion
and Navigation Products
Acuity
develops and sells navigation and motion measurement systems for
use in land, water, and air vehicles. These combine inertial accelerometers
and gyroscopes with magnetic, air pressure, and video sensors to
navigate in enclosed and outdoor environments. The systems may be
used for guidance and navigation on robots and robotic vehicles,
unmanned aerial vehicles, watercraft, and cars, and in virtual reality
and augmented reality systems. Please note that Acuity's equipment
is not yet FAA certified for use in commercial aviation and manned
aircraft.

Imaging Products
Acuity
produces systems for surface profile and shape capture and three
dimensional environment capture. The technologies used include video
based systems as well as laser rangefinding. These products are
used for navigation and path planning in autonomous navigation and
obstacle avoidance, industrial as-built plant modeling, building
and civil engineering structural recording for upgrades and remodeling,
and for virtual reality environment and object capture. by combining
inertial, video, and laser technologies, Acuity offers solutions
for static and moving platform 3D capture requirements.

Introduction Fall 2007
3D
Structured Light Photogrammetry Camera
Acuity
is developing a versatile 3D camera for marketing, animation, industrial
and commercial shape capture applications. This camera will automate
the shape acquisition process for non-specialist use. Until now,
the acquisition of over a million or more 3D points with realistic
color has been an extended process requiring expensive equipment
and professional operators.
Precision
photogrammetry has traditionally required placement of recognizable
targets on surfaces to be profiled. Previous structured light shape
acquisition cameras have required precise placement of the projector
and camera. Both have been limited in their ability to acquire color
and accurately represent shiny surfaces. Acuity's new camera uses
optical surface characterization together with sophisticated pattern
projection to substantially extend the nature and complexity of
objects that may be profiled.

Key
Features
- Captures
shape, color and surface specularity (shininess) information for
realistic presentation of models in simulated lighting.
- Allows
free placement of the camera and projector, for capture of large,
small, and complex objects.
- Captures
up to 1 million 3D points per view. Multiple views may be captured
and combined for higher resolution.
- Freezes motion
in three dimensions. Allows analysis of complex transient and
vibratory behavior by capturing full resolution motion snapshots
with sub-microsecond exposure times.
- Full
field of view (object size) from 3 inches to 30 feet in extent.
With higher projector power options this can be increased to over
100 feet.
- Point
position resolution of 1 part in 10,000, with accuracy of better
than .0005 inches on small objects.
- Automatic
exposure and projector control for easy operation.
Introduction 2008
3D
Environment Capture Video Camera
When
humans move and observe, they combine information from the eyes
and inner ears to form a mental world model using perception of
linear and angular motion as well as visual images. Advances in
projective geometry, position estimates from inertial and magnetic
sensors, and rigid body kinematics can be fused to provide a powerful
new way of effectively generating complete 3D models from video.
Inertial data and camera kinematics can be used with video imagery
to increase the number of image points that can be related across
multiple views, increase the accuracy with which the points can
be related, identify views (video frames) that will efficiently
produce a world model, allow software to combine world model fragments,
and interpret and capture surfaces and regions as well as edges
and vertices in a complete world model.
Acuity
led a DARPA/AAMCOM sponsored development contract to realize the
capabilities possible with these components. This demonstrated the
concept of simultaneous video and inertial data. Acuity is currently
developing and integrating hardware and software to realize a practical
system for navigation and environment capture with freely moving
cameras.
