Embodiment Construction
[0014] figure 1 A structural diagram of a video surveillance system according to an embodiment of the present invention is disclosed. Such as figure 1 As shown, the video surveillance system 100 includes several video acquisition devices 102 , video data preprocessing device 104 , brightness adjustment device 106 , moving object recognition device 108 , display preprocessing device 110 and video display device 112 .
[0015] Several video capture devices 102 each capture a video image within a sub-block range, and the video capture devices 102 output video data. According to an embodiment of the present invention, the area where the gas delivery pipeline is laid is divided into individual block ranges, and each video acquisition device 102 is used to collect video images within one of the block ranges. In one embodiment, the video capture device 102 is a camera.
[0016] The video data preprocessing device 104 is connected to several video capture devices 102, and the video...

The invention discloses a video monitoring system, which comprises a plurality of video acquisition devices, a video data preprocessing device, a lightness adjusting device, a moving target recognition device, a display preprocessing device and a video display device, wherein the video acquisition devices are used for respectively acquiring video images within blocks, and outputting video data; the video data preprocessing device is used for respectively packaging the video data fromof the video acquisition devices into independent video streams; the lightness adjusting device is used for detecting the lightness of the independent video streams, and marking the video streams which are unconformable to lightness indexes; the moving target recognition device is used for recognizing moving targets, conforming to the lightness indexes, in the video streams conforming to the lightness indexes, and marking the moving targets; the display preprocessing device is used for recognizing the video streams which are unconformable to the lightness indexes and are marked by the lightness adjusting device, and the moving targets which are marked by the moving target identification recognition device; and the video display device is respectively used for displaying independent video streams, and carrying out distinguishing display on the video streams which are unconformable to the lightness indexes and remarkably displaying the moving targets in the video streams.
Description
technical field [0001] The invention relates to the monitoring technology of the gas delivery pipeline, in particular to a video monitoring system for monitoring the area of the gas delivery pipeline. Background technique [0002] In petroleum, chemical industry, coal, electric power, metallurgy, coking and other industries, a large amount of reactive gases are used, many of which are flammable, explosive or toxic and harmful gases. Due to the high demand for gases in the above industries, gas pipelines are usually used to transport these gases. Gas transmission pipelines will be laid in a wide range to achieve long-distance gas transmission. The pipelines are usually made of metal or corrosion-resistant non-metallic materials. Although the pipelines are strong, it is inevitable that some Fault. [0003] At the same time, since the gas pipeline is laid in a relatively large area, it is inevitable that people or vehicles will enter the area where the gas pipeline is laid....
