Method and device for constructing panorama staring web camera

Abstract

The invention discloses a method and a device for constructing a panorama staring web camera. The device can directly output a panoramic image in accordance with human eye observation habits, meanwhile can automatically locate and stare a selected interesting area in the panoramic image, and can automatically track and stare a recognized target, and therefore key monitoring can be effectively carried out. The device comprises a speed dome and a panoramic camera, wherein the panoramic camera comprises a panoramic imaging component and an image processing circuit board. According to the scheme, not only can 360 degrees all-in-view monitoring be achieved, but also key staring and monitoring of the interesting area or the recognized target in the 360 degrees view can be achieved.

Description

Technical field: [0001] The invention relates to video surveillance technology, in particular to a construction method and device for a panoramic staring network camera. Background technique: [0002] At present, panoramic technology is more and more widely used in the field of video surveillance. Panoramic monitoring technology uses catadioptric omnidirectional imaging devices or fisheye lenses to capture scene information within a 360-degree range around the device, thereby generating a 360-degree omnidirectional A ring-shaped omnidirectional image of scene information. However, the scene in the omnidirectional image is deformed, and the image is circular and does not conform to the observation habits of the human eye. Therefore, after the omnidirectional image is obtained, it is necessary to process the omnidirectional image, and use computer software to expand it to generate an image suitable for direct observation by the human eye. Long cylindrical panorama image. Wit...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: Aiming at the problem that the cylindrical panoramic image generated by ordinary panoramic imaging device or fisheye lens has a low resolution and cannot focus on observing and staring at the region of interest and the target object, a new method is proposed. The panoramic staring network camera construction method and device, through the close cooperation of the panoramic camera and the high-speed dome, can not only realize the monitoring of the 360-degree all-round field of view, but also can focus on the selected area of ​​interest in the panoramic image and stare at it. Realize the automatic tracking and staring of the recognized target, thus laying a good foundation for the subsequent application of panoramic monitoring technology
