課題とは?

固定レンズカメラは常に狭い視野を非常に詳細にカバーしますが、シーン全体を取り込むことはできません。

シングルセンサーの魚眼カメラは、手頃な価格でパノラマビューを提供しますが、より遠くにある対象の、より詳細な情報を取得するには限界があります。

従来のマルチセンサーパノラマカメラは広い視野をカバーしますが、バックエンド(VMS)でパノラマ表示をするには異なるセンサーの画像を手動で配置する必要があります。この場合、重ね合わせたときに同じ場所が複数のカメラで撮影されたり、カバーされない場所があったり、傾斜して現実とかけ離れた画像が撮影されてしまうなど、全体的なユーザーエクスペリエンスが損なわれてしまう恐れがあります。

問題のソリューション

Is it possible to cover a wide area with just one camera? Hikvision always has a positive response, with its panoramic cameras powered by the Seamless Image Stitching technology and PTZ cameras that feature pan, tile and zoom capabilities and smart functions such as auto tracking. 

Seamless Image Stitching

Image stitching or photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a segmented high-resolution panoramic image. Commonly performed with software, most approaches to image stitching require nearly exact overlaps between images and identical exposures to produce seamless results.

Hikvision employed front-end image stitching technology in its unique, all-in-one PanoVu Series Cameras to deliver 180- and 360-degree panoramas without using any additional servers. The rendered panorama has virtually no visible edges between its stitched images while the brightness and white balance are perfectly blended for a great user experience. So no graphical flaws hinder detailed imaging in the video. 

Seamless image stitching is also the prerequisite for full pan, tilt and zoom functions across entire fields of view. Embedded in the PanoVu Series Cameras, seamless image stitching is used in a wide range of scenarios such as airports, harbors, transit stations, parking lots, stadiums and squares, where coverage of a 180° or 360° field of view is needed.

 

PTZ

A pan-tilt-zoom (PTZ) camera works by moving the camera in different directions to get a whole picture of the surveillance area and zooming in for further detail of security events. The pan, tilt, and zoom capabilities make it possible to monitor large areas with a single camera while getting great detail at the same time.

Hikvision offers a wide selection of PTZ cameras for different application scenarios: high-end DF series network PTZ, AF series Turbo HD PTZ, PTZ positioning cameras, traffic PTZ, and more. These PTZ cameras work well as a standalone solution and integrated with other cameras. With Hikvision’s PTZ cameras, you can rapidly respond to security events and leave no blind spot unnoticed.
