3D Optical Digitizers
Patterned light is projected onto subjects; deformation is recorded by an off-set camera. Triangulation calculates a 3D mesh. Fast, accurate and adaptable for human portraiture.
3D Laser Scanners
A laser line moves over subjects' surfaces; an off-set camera records deformation. Triangulation calculates a 3D mesh. Slower, but higher accuracy enabled for static objects.
3D Mechanical Digitizers
Mechanical arms physically probe objects, guided by the user; points are recorded on the surface of subjects. Intuitive but slow. Unsuitable for delicate objects.
3D Scanning software
View, edit and export scan data efficiently and accurately. Triangulation, registration and merging algorithms, polygon editing, CAD conversion, model export for web viewing.

A compact single camera, which captures 3D
information at video rate. 3DV's technology provides you with 3D imaging, where
each pixel in the scene is tagged with the distance information from the camera,
in real-time.
3DV Systems Zmini
It enables machines abrupt action in situations such as condition
analysis, decision-making and general interactions.
The Zmini provides a real-time Color and Depth information (RGBD) video stream,
by capturing the depth information of each object in the scene in addition to
the RGB values. The depth data is available for all objects within the Field
Of View (FOV) and within the maximum range selected by the operator and segmentation
of a scene using just one camera. The range and resolution of the depth data
is controllable by the user.
At present, we are releasing the Zmini developer's
evaluation kit, which may contribute a great deal to your development efforts
for new revolutionary products that use the third dimension as a tool to see
our 3D world as opposed to the "flat world" image systems currently
produce.
The Zmini can easily be used by various
developers as a base for defining their product using 3DV's proprietary and
patented Parallel Range Sensing (PRS) technology. The main component of the
PRS technology is an imaging electro-optical shutter, which is capable of gating
GHz frequency components, while preserving a low bandwidth collection with an
imager e.g. CCD or CMOS.
Such fast gating enables depth sensing and capturing, which enable the creation
of a depth map.
The Zmini system is based on commercial CCD cameras and supports standard video
formats such as NTSC and PAL. It is a compact camera system with no moving parts,
has a single optical system with linear depth accuracy. The dynamic range is
linearly scaled and adjustable to your needs.
Applications:
The applications addressed by 3DV's Depth Imaging
technology include Consumer Electronics (Gaming, Cellular phones, PDAs); Automotive
(Airbag Deployment, Occupant sensing, Obstacle avoidance, Autonomous Navigation);
Security & Surveillance applications (Face Recognition, Image processing
and Identification); Robotics & Machine Vision (Assembly robots, Pick &
Place, Part Inspection, Measurement & Gauging); Hazardous Area Mapping;
Telepresence & Remote Control; Video Conferencing; Real-time 3D vision for
Medical applications and many other possible applications.
General Description:
The Zmini developer's kit operational concept
relays on full operation and control via the computer unit alone.
The Zmini has the following characteristics:
Full operation in normal indoor environments.
Is a compact portable camera.
Has user friendly interfaces.
Technical Description
Hardware
The system is composed of 3 elements:
Camera
CIM (Control & Interface Module).
Computer
Software
The software controls the camera operation,
camera's automatic adjustment to a scene and diagnosis of the data from the
camera along with generating a visual display of object's depth map or mask.
The software package also allows channeling RGBD information (or only D information
if desired) to an output device required by end-user applications.
Module Functionality and Description
The Zmini System's Features
The Zmini System performs
the following tasks:
1. Standard video rate operation.
2. Fully automated camera control and display including the following capabilities:
a. End-user Man Machine Interface menu.
b. Advanced end-user menu.
c. Monitoring & capturing capabilities.
d. Mode display screen - displays the mask and depth modes.
e. Diagnostic - The system allows a diagnosis of the main system components.
CIM
The control & interface module utilizes the following
signals:
- Input Voltage:100-220V; 50-60 HZ
- Connectors:* Camera unit connector.
* Computer unit connector.
* RGBD information output.
* Raw analog video output.
Camera Unit
The camera unit is built of the following assemblies:
1) D Channel
The D channel is comprised of a narrow band filter, B&W cameras and
an image modulator subassembly.
The output of this channel is a video stream that provides depth information.
2) RGB Channel
The RGB channel is comprised of a standard mosaic 1/2" RGB camera.
This camera is optically matched with the D channel.
The output of this channel is a video stream providing RGB information.
3) Illumination Unit
The illumination board includes 8 laser channels with related optics, classified
as a
Class I Laser Product. As an eye safety product, no exposure
precautions are necessary.
4) Control Board
The control board provides:
- Timing & control for the cameras and illumination board.
- Internal & External synchronization.
