Multi-focal lens linkage imaging camera system based on multi-feature union and Camshift algorithm

Abstract

The invention discloses a multi-target tracking multi-focal lens ultra-high resolution linkage imaging camera system based on combined multi-feature union and Camshift algorithm. The system is mainlycomposed of a video collecting device, a video synthesis processing output system, a video management software and two video output interfaces, whereint he video collecting device comprises a profilecollecting unit for collecting a scene profile in low resolution, ten detail collecting units for commonly collecting ultra-high resolution pictures in detailed part; the acquired video stream is output to a video management software after the video synthesis processing, thereby realizing the collaborative linkage of the scene profile and the ultra-high resolution picture. The system disclosed bythe invention has the following advantages that the scene profiled collected by using as single lens and the ultra-high resolution spliced picture acquired by different lens with different focal lengths are linked to realize the full coverage monitoring without dead corner on the scene, and the monitoring efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of electronic information and relates to image information processing technology, in particular to a multi-focus lens ultra-high resolution linkage imaging camera system based on multi-target tracking based on multi-feature combination and Camshift algorithm. Background technique [0002] At present, in the video surveillance solutions for large-scale areas such as government squares, large parking lots, airport waiting halls, and station waiting halls, the traditional solution mainly uses multiple bolts and high-speed balls. However, the camera with a long-focus lens has a limited field of view, and the camera with a short-focus lens has insufficient resolution to capture distant targets. The observation range of the high-speed ball is limited, and it cannot take into account multiple scenes at the same time. There will be blind spots when using it. ; And for the user, it is very inconvenient to monitor and replay th...

Problems solved by technology

However, the camera with a long-focus lens has a limited field of view, and the camera with a short-focus lens has insufficient resolution to capture distant targets. The observation range of the high-speed ball is limited, and it cannot take into account multiple scenes at the same time. There will be blind spots when using it. ; Moreover, for users, it is very inconvenient to monitor and playback the pictures of multiple cameras, which reduces the monitoring efficiency and increases the difficulty of monitoring

[0003] With the development of video surveillance technology, high-resolution photosensitive chip technology is becoming more and more mature. There are already 12 million pixel CMOS in the market, but it is still difficult for a single camera to meet the application requirements of a large area.
