Category <br> <br> fish-eye panorama camera by a single sensor is supporting a special ultra-wide angle fisheye lens composition, and image correction technology-dependent reduction of fish-eye panoramic image of the camera. Excellent price/performance ratio makes this kind of product occupy the mainstream market share, but the particularity of the fisheye lens will inevitably result in the waste of sensor pixels, and the distortion of the screen edges is difficult to achieve high definition, which means that the visibility within the monitoring range is limited. Coverage area; image correction and virtual PTZ technology is its core technology, based on these core technologies, the current fisheye panoramic camera can be further summarized into three categories:
Software front-end firmware integration (software mode)
All of the camera's functional implementation software, including image correction, virtual PTZ, smart components, and compression algorithms, are all integrated into the camera's internal firmware. Future upgrades also require only updates to the front-end settings. At the same time, its back-end PC can also provide virtual PTZ and other functions, giving the user the flexibility to change the viewing perspective and the possibility of focusing. And because the same amount of computation is very different between hardware crystals and software PCs (the same computing task, when it comes to computing matrix problems, it will occupy a lot of software resources.
Chip front-end implementation (hardware mode)
All functions in this mode are also implemented in the front end, but unlike software front-end firmware integration, it does not allow the retention of original images and subsequent operations. After the user selects the proper function, the machine processes the picture inside the front camera according to the instruction, and then outputs it to the back end to realize the bi-screen or quad-screen effect. The emergence of this approach has given some manufacturers who do not have independent research and development capabilities the ability to "close contact" with panoramic cameras, and it also applies to a certain range of low-end markets. However, all its functions are encapsulated in the finished chip, and it is difficult for manufacturers to further upgrade themselves.
Back-end software implementation
All functions of this type of panoramic camera are implemented by software installed on the back-end PC. The front-end camera is only responsible for capturing images, so the product has advantages in both cost and selling price. Relying on the powerful processing power of the back-end PC, such products do not have the bottleneck of definition upgrade. While implementing basic multi-segment display, virtual PTZ and other functions, the preservation of the original image also enables more information collection in the later period. Processing work. On the other hand, such products have high consumption of back-end PC and network resources, and more back-end servers need to be configured when large-scale projects are used. 
prospect
The advantage of the panoramic camera is that it can achieve the most effective monitoring effect with the least amount of installed capacity, that is, it can reduce the construction costs of guards, wiring, and personnel, etc., and can reduce the monitoring project cost. However, after all, the development time is short (five years), there are disadvantages that can not be ignored, such as the camera unit price is too high, the monitoring distance has not yet been broken, and image storage, restore and other issues, all urgently need to adjust and improve.
Therefore, we cannot blindly pursue the panoramic camera. At present, it is impossible to replace the role and function of the traditional camera. Therefore, how to use a panoramic camera together with a conventional camera to complement each other in order to maximize the monitoring effect is the most important issue that should be considered in addition to technological breakthroughs at this stage.
