Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings.
[0038] Such as figure 1 As shown, a visual measurement and estimation method for substation remnants, including the following steps:
[0039] Step 1: Collect images: use a digital camera to collect video images in the monitoring area, and use a computer to process and display the video images;
[0040] Step 2: VIBE background modeling: use the VIBE method to model the background, and use the model to detect the foreground target in the video image;
[0041] Step 3: Eliminate jitter: perform jitter detection on the video image, detect the foreground part due to jitter, remove it from the video image, and obtain an updated mask and a static target in the foreground;
[0042] Step 4: Model update: use the update mask obtained in step 3 to update the model;
[0043] Step 5: Judgment of remnants: Use the foreground static target obtained in step 3 to determine the remnan...

The invention discloses a visual measurement and estimation method of substation remnants. The visual measurement and estimation method comprises the following steps: a step 1: collecting an image; a step 2: modeling a VIBE background; a step 3: eliminating jitter; a step 5: updating the model; and a step 5: judging the remnants. According to the visual measurement and estimation method of substation remnants provided by the invention, the adopted VIBE background modeling method is simple in process and short in time consumption, so the time consumption in a processing procedure is shortened, and then the detection instantaneity is greatly improved. Jitter detection is carried out on a video image, and a mask with jitter interference removed is used for updating the background to effectively prevent wrong detection of the remnants caused by the jitter or offset of a camera, so as to greatly improve the detection precision. The visual measurement and estimation method disclosed by the invention is used for effectively solving the problem of low detection instantaneity and precision of the remnants in the existing video monitoring and effectively improving the substation safety management means and efficiency.
Description
technical field [0001] The invention relates to a visual measurement and estimation method for remnants in substations, and belongs to the technical field of remnants detection in video monitoring. Background technique [0002] Substation operation management is a tedious job with high safety requirements. A little carelessness in the work will lead to major safety accidents. At present, intelligent video surveillance has been introduced into the remote management of substations. How to detect hidden safety hazards in time and issue alarm information in time is the top priority of substation operation management. [0003] There are many important and dangerous places on the substation site where leftovers are not allowed. The traditional method is to monitor and alarm the current video manually, which is different from the supervision requirements of intelligent video monitoring for real-time online detection and alarm information at the moment of an event. Far, unable to m...
