Problems solved by technology

If an analog camera with panoramic monitoring function is directly connected to an analog video monitor, it cannot achieve panoramic expansion
On the other hand, the analog signal resolution is fixed, how to display panoramic images in fixed resolution mode is also a problem

Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0039] Such as figure 1 As shown, the panoramic analog camera 1 includes: a panoramic imaging device 2 , an image processing circuit board 3 , a network interface (RJ45) 5 , a serial port (RS485) 6 , an analog video output interface 7 and other interfaces 4 .

[0040] The panoramic imaging device 2 can be composed of an imaging component connected to a fisheye lens, or can be composed of an imaging component connected to a common lens and then connected to a catadioptric quadric surface, or can be other panoramic imaging devices.

[0041] The imaging component is: a CCD imaging component, or a CMOS imaging component.

[0042] The working principle of the camera: the panoramic imaging device 2 collects images of the surrounding 360 field of view to obtain an omnidirectional image, and the omnidirectional image is input to the image process...

Abstract

The invention discloses a panorama-spreading system for an analog video monitor. The system can directly output the analog video signals of panoramic images meeting the viewing habit of the human eyes, and can be directly connected with the monitor for monitoring. The system comprises a panoramic imaging device and an image processing circuit board, and is provided with an analog video signal interface, a network interface RJ45 and a serial port RS485, the analog video signal interface is used for outputting analog video signals, and the network interface RJ45 and the serial port RS485 are used for controlling a camera. On the basis, the invention also discloses a variety of panoramic image-spreading methods, which can spread omnidirectional images into panoramic images which are suitable for the viewing habit of the human eyes and meet analog video resolution. According to the scheme provided by the invention, the panorama-spreading system can be directly connected with the panoramic camera of the analog video monitor, thus realizing 360-degree full-visual field monitoring.

Description

Technical field: [0001] The invention relates to video monitoring technology, in particular to a panorama unfolding system and a panorama unfolding method for an analog video monitor. Background technique: [0002] Panoramic monitoring technology uses a fisheye lens or a catadioptric omnidirectional imaging device to generate a ring-shaped omnidirectional image containing 360-degree omnidirectional scene information in space. Expanding the omnidirectional image can generate a cylindrical panoramic image suitable for direct observation by human eyes . With the advantages of 360-degree all-round vision, panoramic surveillance technology has been widely used in the field of video surveillance. [0003] Omnidirectional images include 360-degree omnidirectional images, but they do not conform to the observation habits of human eyes. After the omnidirectional images are acquired, the omnidirectional images need to be processed and unfolded into panoramic images that conform to th...
