Wide-angle video monitoring device and method for multiple IP cameras

Abstract

The invention discloses a wide-angle video monitoring device and method for multiple IP cameras. The wide-angle video monitoring device and method mainly solve the problem that the monitoring range of a single camera is small, in other words, when the monitoring angle of the camera is large, the monitoring distance is not long, and when the monitoring distance is long, the monitoring angle is not large enough. The monitoring device comprises an image collecting device, a data transmission device and an image processing device, the IP cameras are integrated on the image collecting device and are matched to form a wide-angle monitoring camera, the data transmission device is connected with the IP cameras, and the image processing device is connected with the IP cameras through the data transmission device, splices images collected by the adjacent IP cameras into a monitoring video and outputs the monitoring video in real time. The wide-angle video monitoring device and method conduct local image comparison and calibration based on the SIFT algorithm, image fusion is conducted based on wavelet transformation, and then real-time display is conducted in a BITBLT mode.

Description

technical field [0001] The invention relates to a video monitoring device, in particular to a wide-angle video monitoring device with multiple IP cameras, and also to a monitoring method thereof, which is suitable for real-time monitoring of plane video with a long-distance 180° viewing angle. Background technique [0002] Currently, known video surveillance camera products all adopt a single camera monitoring method, that is, a lens with a predetermined focal length and a camera module with predetermined pixels are assembled. For example, the surveillance camera products currently on the market basically use 1.25mm, 2.8mm, 4mm, 6mm lens and 2 million pixel camera module are assembled. [0003] However, the video monitoring equipment with this structure is limited by the visual range of the lens, and cannot achieve a wider monitoring visual effect. Moreover, due to the relationship between the performance of the lens and the camera module itself, at present, if you want to ...

AI Technical Summary

Problems solved by technology

However, the current multi-camera monitoring method is extremely difficult to meet the above requirements.

[0020] To sum up, it can be seen that if the current surveillance cameras want to achieve a wider monitoring range, they need to sacrifice the monitoring distance, and it is difficult to achieve both, and the existing surveillance cameras have relatively large restrictions on the monitoring of the surveillance personnel.
