Embodiment 1

[0038] A video high-speed frame difference backup system includes a target extraction module, a refresh rate control module, and a frame difference backup module.

[0039] The target extraction module is used to extract the bounding box of the target of interest in the real-scene image frame of the scene.

[0040] Take the computer room scene as an example. Collect video images through the camera to obtain a large amount of video data. The video data is sampled to obtain image data, so as to reduce the amount of calculated data. For different cameras, the captured videos usually have different frame rates. Generally speaking, video information is highly redundant, so sampling is required. The frequency of sampling can be determined by the implementer according to the specific application scenario. For example, for the video frame rate captured by the camera For example, if the sampling rate is set to 5, that is, the video captured by the camera has 30 pictures (video fra...

[0052] The refresh rate control model is as follows: , That is, the refresh rate of the camera, is the number of bounding boxes, Respectively, the width and height of the bounding box in the image, is the average width and average height of the bounding box (for example, if there are three bounding boxes, the length and height are [150,100], [125,150], [235,200] respectively, then the average width of the bounding box is 170, and the average height is 150), Thermally image the temperature for the scene The hyperparameters in , Indicates the K temperature values ​​with the highest temperature in the thermal imaging of the scene, K indicates the number of temperature values, It is used to measure the air outlet wind speed of the monitoring object an anemometer reading, for the first The amplitude value of the sound collected by each pickup, That is, the number of servers can also represent the number of pickups and thermal anemometers. is the weight facto...

Abstract

The invention discloses a video high-speed frame difference backup system. The system comprises: a target extraction module used for extracting an interested target bounding box in a live-action imageframe of a scene; a refresh rate control module which is used for performing real-time feedback control on the video refresh rate according to the attribute of the interested target bounding box, theabnormal temperature in the scene thermal imaging, the sound in the scene and the air speed of the air outlet of the monitored object in the scene which are obtained in real time; and a frame difference backup module which is used for carrying out frame difference backup on the live-action image frame, and the frame difference backup is carried out according to the interested target bounding box,the thermal imaging temperature anomaly ROI and the sound anomaly area. By utilizing the frame difference backup method and device, the frame difference backup efficiency is improved, and the storagespace of frame difference backup is reduced.

Description

technical field [0001] The invention relates to the technical fields of video processing and computer vision, in particular to a video high-speed frame difference backup system. Background technique [0002] The use of cameras is becoming more and more popular, and it has become a necessary equipment for monitoring links in various industries. However, there will be malfunctions in the camera. If the device malfunctions, the video display will be interrupted or the screen will be black, resulting in data loss. Therefore, it is very necessary to back up the video in real time and efficiently to ensure the integrity of the video data. Some methods utilize key frame detection methods for frame difference transmission. Although these methods can achieve some image compression effects, the compression rate is low, and the backup effect is poor in specific environments such as computer rooms. Contents of the invention [0003] The present invention proposes a video high-speed...
