Video monitoring device capable of hiding anti-counterfeiting shooting watermark in real time

Abstract

The invention discloses a video monitoring device capable of hiding an anti-counterfeiting shooting watermark in real time. A monitoring video imaging optical path is orderly composed of a monitoring camera lens, an optical imaging lens group, a light splitting device and a monitoring camera CCD; a watermark imaging optical path is orderly composed of a low-power adjustable light source, a collimating lens, a watermark transmitting mask, a watermark imaging lens group, the light splitting device and the monitoring camera CCD; the light splitting device and the monitoring camera CCD are shared by the two imaging optical paths, wherein the light splitting device is mounted at an orthogonal position of the monitoring video imaging optical path and the watermark imaging optical path, and combines the two paths into one path, thereby, incoherent superposition of a watermark image and a monitoring video image is realized. According to the invention, the anti-counterfeiting shooting watermark is hidden in the monitoring video by physical means in real time, so that the video monitoring device improves anti-counterfeiting properties and reliability of the monitoring video, and then guarantees credibility of the monitoring video from a technical point of view, is more easier to realize, and facilitates reduction of system cost.

Description

technical field [0001] The invention belongs to the field of anti-counterfeiting technology of video monitoring, and in particular relates to a video monitoring device for hiding and photographing anti-counterfeiting watermarks in real time, a corresponding use method and a watermark detection method thereof. Background technique [0002] Video surveillance is an important part of the security system. Traditional surveillance systems usually include front-end cameras, transmission cables, and video surveillance platforms. Cameras can be divided into network digital cameras and analog cameras, which are used to collect front-end video image signals. The monitoring system is a comprehensive system with strong preventive ability. Its monitoring video is widely used in many occasions because of its intuitiveness, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, video...
