specific Embodiment approach 1

[0025] Specific implementation mode one: combine figure 1 Describe this embodiment, this embodiment comprises eight-way camera 1, a multimedia processor 2 and a support 3, and described eight-way camera 1 is the camera that focal length is the same and angle of view is 60 degrees, and support 3 is a regular octahedron Body frame, a camera is respectively installed on the eight sides of the octahedral cylinder frame, each camera is located at the center of its installation side, the optical axes of the lenses of all cameras are located in the same plane, and each The included angle between the camera and its installed side is the same, and the image data output ends of the eight-way camera 1 are respectively connected with eight input ends of the multimedia processor 2, the multimedia processor 2 is used for digital image processing, and the multimedia processor 2 Located in the regular octahedron base. The multimedia processor 2 is a DSP microprocessor based on the TMS320DM64...

specific Embodiment approach 2

[0026] Specific implementation mode two: combination Figure 1 to Figure 7 Describe this embodiment, the steps of this embodiment are as follows:

[0027] Step 1: Use eight-way video to collect images, and install cameras with the same focal length and 60-degree field of view on the eight sides of the regular octahedron. The center and the angle should be kept consistent, so as to ensure that the direction of the video picture collected is consistent, and the size of the scene in the image is consistent, and sent to the multimedia processor 2;

[0028] The fields of view of the two cameras located on the adjacent two sides of the regular octahedral cylinder have a 7.5-degree field of view overlap, that is, there is a 7.5-degree field of view overlap between every two adjacent images, which can be Video image stitching provides convenience.

[0029] Step 2: image splicing: Utilize the improved SIFT algorithm to seamlessly splice the eight-way video images input to the multime...

Abstract

The invention discloses a panoramic monitoring system and a monitoring method of the same based on improved SIFT feature matching, which relate to the field of panoramic monitoring systems, and solve the problem that the monitoring system currently existing on the market cannot really realize real-time panoramic monitoring. Eight cameras respectively have same focal length and a 60-degree field angle, and eight side faces of a regular octagon column base are respectively provided with one camera; each camera is located at the center of a mounting side face thereof, an optical axis of a lens of each camera is located in the same plane, and an included angle between each camera and the mounting side face thereof is same; image data output ends of the eight cameras are respectively connected with eight input ends of a multimedia processor, the multimedia processor is used for processing digital images, and the multimedia processor is located in the regular octagon column base. Eight images input into the multimedia processor are spliced together in a seamless manner through the improved SIFT algorithm so as to form a complete and continuous panoramic image. The system and the method are suitable for the fields of security monitoring, emergency rescue and disaster relief, and military.

Description

technical field [0001] The invention relates to multiple fields of digital image processing, embedded technology and mechanical structure, and specifically relates to the field of a panoramic monitoring system. Background technique [0002] The issue of security prevention has been the focus of general attention from all walks of life in recent years. With the development of society, security prevention has developed from simple fire prevention and theft prevention in the past to a broad category that guarantees the rational operation of the entire society. Under this background, security monitoring products have come out one after another. Even so, people are constantly pursuing smarter, simpler and more humanized products. [0003] The existing monitoring products can be roughly divided into the following categories: [0004] 1. Single camera camera. This method is suitable for simple narrow scenarios, such as the monitoring of road lanes. Because the field of view of ...
