What
is Mesa's time-of-flight
Swiss Ranger 4000 camera and how does it work?
The Swiss Ranger 4000 provides high-resolution 3D image data in
real time.
The device relies on an image sensor technology capable of capturing 3D
data sets (known as depth maps) in real time and is built into a single,
compact, solid-state housing.
At the heart of the camera is an advanced sensor technology employing
the time-of-flight distance measurement principle where infrared light
from the camera's internal lighting source is reflected by objects in
the scene and travels back to the camera where its precise time of arrival
is measured independently by each of tens of thousands of sensor pixels.
Two measurement range models are available up to a distance
of 10 metres. Date is output via USB 2.0 or Ethernet to a computer
for visualisation, interpretation and processing. Various models are available
to be matched to user needs.
What is "Time-of-Flight"? |
|
Time-of-Flight describes a variety of methods used
to measure the time it takes for an object, particle or wave to travel
a distance through a medium. This measurement can be used for a time
standard, as a way to measure velocity or path length through a medium
or as a way to learn about the particle or medium. |

What is a "Time-of-Flight"
camera? |
|
A time-of-flight camera is a vision system that
creates distance data using the time-of-flight principle where the
entire "scene" is captured with each laser or light pulse.
Time-of-flight cameras are relatively recent devices for normal products
as the semiconductor processes inherent in the product have only recently
become fast enough for such devices. The system covers ranges from
a few meters up to several kilometers, depending on the detector material
being used. |
What advantages
does Mesa's SR4000 time-of-flight camera have ? |
Mesa's time-of-flight-based measurements have
several important advantages compared to other 3D imaging technologies,
such as laser triangulation or stereoscopic vision systems: |
Measurements are not dependent on external reference points or
presence of contrast in the surface of measured objects. |
Real time, video frame rate measurements independent
of scanning cycles or limitations imposed by computer processing power. |
Scene illumination is provided by the camera, and is not dependent
on illumination from external, visible light. |
Larger objects can be measured easily without
any increase in camera base length (as with stereo vision). |
Camera directly delivers depth values for each pixel, without the
need of complex calculation algorithms. This results in faster, less
computation intensive systems and allows for direct integration of
application algorithms onto the DSP of the camera. |
Key features of the SR4000
camera |
** |
Industrial-grade camera allowing for
high-quality measurements in demanding environments. |
** |
Stable measurements are guaranteed through a self-calibrating
optical design |

Where can I use the Swiss
Ranger 4000? |
|
Applications include: |
Machine Vision:
More general machine vision applications require highly stable and
reliable sensory systems. The MESA camera, supplies a reliable set
of depth data which increases the robustness and flexibility of many
surveillance, inspection, and logistics systems. Specific applications
in this field include: |
** |
Single-camera-based factory automation via identification
of an object's location, volume, and orientation |
** |
Replacement of space-consuming infrared light curtains used to monitor
workers in the proximity of dangerous equipment |
|
Robotics:
The search for real-time electronic robotic eyes that closely mimic
the behaviour of human eyes has been a high priority for some time.
The SR400 avoids the shortcomings of alternative solutions such as
stereoscopic cameras or laser scanners. One Mesa camera allows a single
compact sensor to serve as a highly capable input device in many robotic
applications, including: |
** |
Autonomously-guided vehicles with improved obstacle identification
and avoidance - for map building, localisation and path planning. |
** |
Service robots in both industrial and consumer applications. |
** |
Industrial robots in assembly, quality control monitoring, material
handling, and automation. |
|
Other applications include: |
Logistics:
For detecting and measuring volumes of freight in a very short time
by providing fast data acquisition and a small system size with no
need for mechanical scanning devices. |
Security / Surveillance:
the third dimension delivered by the SR4000 allows for much easier
segmentation of images, for example, it allows of determination of
presence, location and number of persons or objects in a target zones. |
|
Medical and Biometrics:
The ability of the SR4000 camera to provide immediate, cost-effective
images enables a diverse set of emerging medical and biometric applications
such as: |
** |
human-machine interface for geriatric rehabilitation
computer games |
** |
clinical use of Time-of-flight for patient-position and patient-movement
monitoring to increase effectiveness of therapy (including radio therapy) |
** |
Providing laparoscopic surgeons with a surface dimension to assist
in endoscopic surgery procedures, enabling the marriage of the real-time
image to previously generated scanned images. |
