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 equipment 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 fr...

[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 kth temperature value with the highest temperature in the scene thermal imaging, K indicates the number of the highest temperature value, 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, and it can also represent the number of pickups and thermal anemometers. is the w...

Abstract

The invention discloses a video high-speed frame difference backup system. Including: a target extraction module, which is used to extract the bounding box of the target of interest in the real-scene image frame of the scene; Real-time feedback control of the video refresh rate by the sound of the sound and the wind speed of the air outlet of the monitored object in the scene; the frame difference backup module is used to perform frame difference backup of the real-scene image frame, and the frame difference backup is based on the bounding box of the target of interest and the abnormal temperature of the thermal imaging ROI and abnormal sound areas are backed up by frame difference. The invention improves the efficiency of frame difference backup and reduces the storage space of frame difference backup.

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...
