Four key technologies of panoramic camera

First, the quality of the camera will greatly affect the quality of the surveillance image; a good lens can reach HD, more than megapixels, and the higher the frame rate (the speed of animation transmission per second), the better the target can be seen. Movement process and detail action.

Second, a good panoramic camera must have a high-resolution image sensor. Due to the wide monitoring range of the panoramic camera, the information volume of the image sensor must be very large. Unlike the general camera, it only needs to process a part of the screen in the monitoring scene. Therefore, whether the resolution of the image sensor is high or low is also the key to affecting the image clarity after the monitoring image is enlarged.

Thirdly, a panoramic camera using a fisheye lens has different imaging principles than an ordinary camera, and the image edge often forms a convex and distorted image. Therefore, it is easier to distort or distort the image than an ordinary camera, which affects the image quality. Therefore, how to correct and restore images and see the monitoring objects in the images is the most important problem of the panoramic camera.

Theoretically, there are two ways to correct the problem of fisheye lens imaging distortion. One is to process information by the backend platform and restore imaging; the other is to directly correct the camera's built-in software and then transmit it to the monitoring backend. . In general, it is recommended to use the latter to solve the problem of fisheye lens distortion, which can relieve the pressure of network transmission broadband and backend storage and improve the efficiency of monitoring operations.

Fourth, you can use virtual PTZ to zoom in and zoom out details of stored images. In the field of security monitoring, PTZ controls the pan/tilt/left/right rotation and the lens change focus. It is used to automatically or manually track and lock the target. It tracks the target all the way within the monitoring range. The virtual PTZ used by the panoramic camera has a similar concept to that of the pan-tilt, except that the actual mechanized rotation does not have to be performed like a real pan-tilt, but rather the similar effect is achieved by zooming the image, thereby greatly increasing the monitoring system. The service life makes it easier for the monitoring personnel to operate and reduce maintenance costs.
