Problems solved by technology

[0010] The purpose of the present invention is to provide a multi-focus lens linkage imaging device based on multi-target intelligent tracking. This invention solves the problem that it is difficult to take into account the clear imaging of distant targets when only relying on a set of monitoring devices for real-time monitoring of large-scale areas in the prior art. and the limitation of full coverage monitoring of the entire scene; and the monitoring omission caused by the continuous switching of close-range imaging and long-range imaging of the camera pan-tilt device; the technical problem that the existing median filtering algorithm has a poor filtering effect on noise-dense areas

Embodiment Construction

[0054] The accompanying drawings constituting a part of this application are used to provide further understanding of the present invention, and the schematic embodiments and descriptions of the present invention are used to explain the present invention, and do not constitute an improper limitation of the present invention.

[0055] In order to overcome the deficiencies of existing monitoring schemes in the application of video monitoring in a large area, the present invention provides a multi-focus lens linkage imaging device based on multi-target intelligent tracking. It only needs to install a set of equipment in the monitoring area, which can replace all the monitoring equipment required in the existing monitoring scheme, and it is easy to operate and use. The device includes a video acquisition module, a storage module and a video management module 400 .

[0056] see figure 1 The video acquisition module includes at least one overview acquisition unit 110 and at least t...

Abstract

The invention provides a multi-focal length lens linkage imaging device based on multi-target intelligent tracking. The device monitors large-range areas by using a multi-focal length lens at the same time, the horizontal viewing angle of a collected image with an ultra high resolution is larger than 90 degrees, so that the device can achieve full coverage without dead angle in large range scene monitoring, and the pixel density of the collected image is larger than 125 pixels/m within a range of 130m away from the device, so that the pixel of the entire monitoring image is larger than a hundred million.

Description

technical field [0001] The invention relates to the field of image imaging technology, in particular to a multi-focus lens linkage imaging device based on multi-target intelligent tracking. 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 existing monitoring solutions mainly use multiple bolts and high-speed balls for monitoring. The existing long-focus lens bolts have a limited field of view; and the bolts equipped with short-focus lenses can only obtain target images with insufficient pixels for distant targets; The whole scene and the part can get local enlarged and full-view images with accurate correspondence at the same time, and there will be blind spots when using it. For users, when adopting the existing monitoring scheme, it is necessary to switch between the images of multiple cameras to monitor, which is very in...
