Example Embodiment

[0026] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] In the description of the present invention, it should be understood that the attached figure 1 The "junction 1", "junction 2", "cloud icon server", etc. indicated in the represent the location of the method. To simplify the description, it is assumed that there are two edge computing tasks at traffic intersections, which does not mean that the present invention is limited to Two edge devices and one cloud server. In addition, figure 2 The terms "Inception–v4", "Interframe Difference", "Faster RCNN", "Raspberry Pi", "Pi Cam", "PostgreSQL" and other terms marked in the text are only to describe this description clearly, not actual applications It needs to fix the equipment or method used in the device, so it cannot be understood as a limitation of the present invention. In addition, the case of "traffic monitoring video" is used to illustrate...

Abstract

The invention discloses a video analysis method in an edge cloud environment. The method comprises the following steps: preprocessing video data at an edge end, sending a foreground image to a next edge device for model reasoning through an MQTT message transmission protocol, classifying and identifying targets appearing in a video, and finally uploading a classification result to a cloud database. The method has the characteristics of reducing the transmission load, reducing the bandwidth loss, and improving the recognition precision and recognition speed of the neural network model.

Description

technical field [0001] The invention belongs to the technical field of edge computing, and in particular relates to a video analysis method in an edge cloud environment. Background technique [0002] With the rapid development of the Internet of Things, big data, and cloud computing technologies, the number of edge sensors and monitoring devices is also increasing rapidly in the environment of the Internet of Everything, and generates data. These massive data need to be processed in a timely manner. Otherwise it will cause a lot of congestion. However, due to the limitations of bandwidth and resources in the existing centralized cloud computing service mode, it is no longer possible to process the data generated by these devices in real time and efficiently, and directly uploading the original data collected by the edge to the cloud will inevitably cause network bandwidth load and waste of computing resources. [0003] These devices will generate a large amount of data rel...
