Abstract

The invention discloses a splicing device for a real-time high speed high definition panoramic video and a method thereof. The method comprises the steps: S10, obtaining spliced multipath real-time video sequences; S20, judging whether video images at the same moment in any two paths of video sequences meet the image splicing condition; S30, calculating an image splicing parameter; S40, selecting a projection face and mapping the video images in the multipath real-time video sequences to the same mapping face according to the splicing parameter, then determining the panoramic projection face; S50, establishing a mapping table of pixel points on the video images and coordinate points of the overall projection face; S60, conducting exposure and fusion processing on pixel values of all the coordinate points on the panoramic projection face and outputting the panoramic video images according to the pixel values. The splicing device for the real-time high speed high definition panoramic video and the method of the splicing device can greatly improve splicing efficiency of the images, ensure output quality of the images, and meet the requirement for real-time high speed high definition panoramic video.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a real-time high-speed high-definition panoramic video splicing device and a method thereof. Background technique

[0002] With the rapid development of monitoring systems today, the emergence of high-definition cameras allows people to see more clearly and obtain more details. However, people have put forward another requirement, that is, they can see more in the same scene. thing. The original method is to solve it by covering an area with several cameras, or using a fast dome to cruise and scan back and forth. But in some occasions, these methods can not fully meet the user's requirements, such as the need to determine the movement of people in the same screen, or need to use the things monitored in the same scene to explain some problems, this time you need panorama camera. The panoramic camera hardware in the prior art is divided into five modules: a video acquis...
