Unique technology of creation of circular panoramic image in
real time
Continuous capturing of circular panoramic image can be very
advantageous for many applications. Image from panoramic cameras
provides the best overview of the camera vicinity. This is
especially useful for monitoring and security systems in open
landscape as well as in large halls, shops and stores, parking
lots etc. Panoramic cameras also offers the best possible overview
of mountain ski centers, beaches and other areas.
Most common way to create panoramic image is employing of
standard camera rotating around vertical axis. Image is then
created during camera rotation. But this method works only for
static images with long periods of image refresh. Sometimes are
panoramic images created by special line-scanning devices with
rotating mirrors. Such cameras are rather complex, image refresh
time is pretty low and sensitivity is very low. DataCam offers
solution in the form of camera head with four cameras offering
filed of view 360° × 160° or single
hemispherical camera with 360° × 90°
field of view. High quality digital DataCam®
cameras with high dynamics and low noise are used in both cases.
The front optical plane of the used lenses works as neutral
density filters changing the transparency according to light
conditions. This results into capability to capture scenes with
bright lights as well as dark shadows. Perfect image stitching is
accomplished thanks to precision camera head calibration by the
software running in the computer GPU.
The DataCam® digital CCD cameras
offer number of features:
panoramic image up to 360 × 160°
no moving parts
high sensitive CCD detectors
color and monochrome versions
various resolutions and CCD sizes
16 bit digitization
very low image noise
several connections available:
USB 2.0
Ethernet
wireless data link
transfer of RAW data without compression artifacts and
information loss
safe 8 to 40 V DC power
only 6W consumption
compact and robust aluminum case
weather resistant
Easy to use in the Control Web
® rapid application development system:
highly parallel real-time image processing in the
GPU
capability to process geometry of several hundreds of
images per second on single PC
image transfer over a network
storing and archiving of image
easy image processing integration into
applications
Perfect overview in single image
It is possible to display complete panorama or any sub-frame in
the desired resolution. Capability to enlarge the image of course
depends on the resolution of used cameras.

High image dynamics is useful when capturing the scene
with different lighting

Demanding scene contains both shaded interior and
sunlit exterior parts

Panoramic image provides the best possible overview of
the vicinity
Software
Massively parallel image processing in the GPU (Graphics
Processing Unit) enables real-time image processing, previously
available only in off-line RAW converters. The software also
allows many other ways of image processing—denoising, sharpening, color saturation, motion
detection, edge detection, etc. Integration with the
Control Web rapid application development system
opens the whole world of process control, supervision and
monitoring application as well as interoperability through
standard protocol like HTTP or OPC, access to SQL databases,
communication with numerous industrial devices and I/O units
etc.
