New generation of panoramic fisheye camera

Author : TT Date : 6/15/2016 7:18:37 AM

Fisheye camera also known as panoramic camera, it use a special lens, so that the camera can achieve video surveillance without dead ends, such cameras come to the market in 2008, however, it has been no large scale application due to the cost and image clarity problem.

 

The early fisheye camera, using a about 1.17mm lens install in a 2 Megapixel high-definition IP camera, the camera obtain a panoramic image data, and send it back to PC Client, use the softwares on the PC Client to correct the deformation date of the camera, and get the image that can be suitable for human viewing habits. However, this type fisheye IP camera cost is very high, because most of projects only need one or two panoramic cameras, the cost of camera and PC, add together, it will be high.

 

In about 2013, a new panoramic camera came to the market, which can take image acquisition and image correction done in one camera without use a PC for image correction job. However, due to the limitations of the processing chipset of this type camera, the chipset can only correct 1.3 Megapixel image data or less, if higher, it cannot do anything. As we know, the panoramic camera want to achieve long range monitoring, usually need 2 Megapixel camera or higher, then it has a use value, divided equally to every detail of the part of the pixel can be sufficiently restored.

 

Based on the disadvantages of 2 type panoramic cameras, TT INT'L has invested enormous human and material resources, developed the new generation of panoramic fisheye cameras. it use 3 Megapixel image sensor for data collection, it send the data to a powerful image correction chipset, make it into a suitable viewing image, the camera built-in E-PTZ function, to achieve the images that after correction can rotate, zoom in and out and other digital control. The camera main stream as below picture 1, one image is divided into four different screens, the sub stream is after correction. The panoramic camera is also all-in-one control, no need control by PC client, the camera will achieve fisheye separation and correction functions. And a substantial increase the output pixel, the camera effective output pixel is 1080P.
