360 Panorama & Dewarping
To maximize the benefits of the 360-degree lens, digital manipulation of the native image is required. The process is called “dewarping” and allows for any area of the original warped fisheye to be converted to have the look and feel of a more traditional video stream. A user can then move around the image and look at different parts of it in a more natural and conventional way.
Onboard vs. Client-side dewarping
With Onboard dewarping, the image is dewarped inside the camera itself and the resulting image is streamed as an independent view across the network. The resulting image is sometimes referred to as a Vcam or “Virtual Camera” and depending on the specification of the 360-degree camera, multiple Vcams can be produced at the same time. When client side dewarping is used, the whole fisheye image is transmitted across the network and recorded in full by the VMS or NVR. The dewarping is then carried out on the client and can be done on both live and recorded footage – meaning full retrospective dewarping of the scene is possible.
True Panoramic+
The unique lens placement of the Evolution 180 range maximises the horizontal use of the image sensor to provide more pixels on target compared with traditional 360-degree derived wide angle views. Oncam’s Angle Compensation Technology (ACT) corrects the angled view, straigtening vertical lines in the scene.
Global Standards
ONVIF is an open industry forum for the development of a global standard for the interface of IP-based physical security products. The ONVIF specification will ensure interoperability between products regardless of manufacturer.
Oncam is proud to be a Contributing Member of the Open Network Video Interface Forum (ONVIF). Our range of 360-degree and wide-angle cameras are all ONVIF Profile S conformant and will integrate with third-party products that comply with the ONVIF specifications for Profile G and S.
