The Swiss Ranger 4000 3D, time-of-flight
industrial camera provides high-resolution 3D
image data in real time.
The device relies on a 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 suited to harsh environments.
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 ranges are possible up to a distance
of 10 metres and the data is then delivered via USB 2.0 or Fast
Ethernet to the computer for visualisation and interpretation. Various
models are available to be matched to user needs.
| Advantages of Mesa's SR4000 time-of-flight camera over other 3D cameras |
| 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 |

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, localisaton and path planning. |
| ** | Service robots in both industrial and consumer applications. |
| ** | Industrial robots in assembly, quality control monitoring, material handling, and automation. |
| 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 SR400 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. |
