Problems solved by technology

These monitoring systems do not have "intelligent monitoring" functions, and cannot automatically distinguish "abnormalities" that appear in the screen according to the behavior characteristics of the observed objects, implement target detection, tracking, classification and behavior analysis, and intelligent alarms to effectively prevent incidents from happening
In addition, the method of "passive storage, after-the-fact evidence collection" requires a large amount of storage space, and also consumes a lot of manpower and material resources

Embodiment 1

[0139] Figure 1 is a schematic structural diagram of a panoramic video intelligent monitoring system, including:

[0140] The front-end panoramic imaging device 10 is used to acquire the panoramic video information of the scene, and monitor the scene at 360° without blind spots. The front-end panoramic imaging device 10 transmits the acquired on-site panoramic video information to the intelligent analysis and processing device 20 .

[0141] The intelligent analysis and processing device 20 is used to intelligently analyze and process the on-site video information transmitted from the front-end panoramic imaging device 10. After an alarm event is detected, an alarm message is generated, and the encoded on-site video information is combined with the intelligent The analysis and processing results are sent to the intelligent monitoring platform 50 and the local monitoring terminal 40 together with the alarm information, and at the same time, the external equipment 30 is controlle...

Embodiment 2

[0157] The equipment for intelligent analysis and processing of panoramic images includes modules as shown in Figure 3:

[0158] Panoramic image expansion processing module 310: used to expand the on-site panoramic image transmitted from the front-end panoramic imaging device 10, and transmit the panoramic expanded image to the moving object detection module 320;

[0159] Moving object detection module 320: used for performing object detection when the panoramic image expansion image transmitted from the panoramic image expansion processing module 310 changes, and extracting the foreground object of the current frame;

[0160] Moving object tracking module 330: for tracking the moving object detected by the moving object detection module 320;

[0161] Moving object classification module 340: for performing type identification on the moving object;

[0162] Wherein, the type identification is performed according to the detected basic data information such as the position, size...

Embodiment 3

[0182] As shown in Figure 5, it is a schematic diagram of the 360° unfolding principle of a panoramic image, and Figure 6 is a schematic flow chart of a 360° unfolding method, and the specific process of 360° unfolding is described as follows through Figures 5 and 6:

[0183] Step 601: Since the origin of the original panoramic image is at o, firstly, through coordinate transformation, the origin o of the coordinates is transferred to the center position o' of the circular panoramic image to establish a new coordinate system. Corresponding to each pixel in the image, the coordinate transformation formula is x'=x-w / 2, y'=y-h / 2, where x is the abscissa of the pixel in the panoramic image in the original coordinate system, and x' is the panoramic image The abscissa of the pixel in the new coordinate system, y is the ordinate of the pixel in the panoramic image in the original coordinate system, and y' is the ordinate of the pixel in the panoramic image in the new coordinate system...

Abstract

The invention discloses a panorama video intelligent monitoring method, comprising: A. acquiring a scene panorama image and unfolding it; B. performing intelligent analysis on a moving target in the panorama unfolded image. The invention also discloses a panoramic video intelligent monitoring system, a device for intelligent analysis and processing of panoramic images, and a method and device for unfolding panoramic images. By using these methods, systems, devices and devices, it is possible to reduce Installation cost, automatically distinguish "abnormalities" in the screen, and implement moving target detection, tracking, classification and behavior analysis, realize intelligent alarm, effectively prevent incidents from happening, and save manpower and material resources.

Description

technical field [0001] The invention relates to video monitoring technology, in particular to a panoramic video intelligent monitoring method and system. Background technique [0002] The video acquisition module of a conventional video surveillance system is mostly composed of a video camera and a lens, because the size of the imaging device is limited, and due to the obstruction around the lens when receiving incident light, the lens only has a small field of view of a conical area instead of a hemisphere, Therefore, it is not possible to obtain all the information of the scene and realize 360° panoramic uninterrupted monitoring. In order to achieve panoramic monitoring, it is necessary to install multiple cameras to cover all the monitoring areas. Not only the cost of cameras and camera installation costs are greatly increased, but also the cost of storage, display and other equipment is also greatly increased with the increase in the number of cameras. [0003] For pano...
