Embodiment 1

[0060] A DDNN based on cloud-edge collaborative computing is applied to object classification under multi-view images of the Internet of Things, including edge side and cloud.

[0061] Among them, the edge side is used to extract the features of each viewing angle image, and the feature bag model is used to measure the similarity of the extracted feature images and obtain the histogram vector of the viewing angle; the histogram vector of each viewing angle Based on the fused histogram vector, the target classification on the edge side is obtained. If the target classification does not meet the accuracy requirements, multiple feature images of each view are transmitted to the cloud; the cloud is used for all Feature weighted fusion is performed between multiple feature images, and convolution and classification operations are performed on the fused feature images to obtain the target classification in the cloud.

Abstract

The invention discloses a DDNN based on cloud-edge collaborative computing and its construction method and application, which are applied to object classification under multi-view images of the Internet of Things. DDNN includes: an edge side, which adopts a feature bag model to extract multiple features The similarity of the image is measured and the histogram vector of each view is obtained statistically; the feature weighted fusion is performed on the histogram vector of each view, and the classification of the edge side target is obtained based on the fused histogram vector. If the classification accuracy is not enough, the extracted The feature images of each viewing angle are transmitted to the cloud; the cloud is used to carry out feature weighted fusion of all feature images, perform convolution and classification operations on the fused feature images, and obtain the target classification in the cloud. The present invention introduces a feature bag model on the edge side to reduce the amount of parameters; in addition, multi-view weighted feature fusion reduces multi-view redundant features and increases the effectiveness of feature expression capabilities. The invention reduces the amount of parameters of DDNN and the traffic of cloud-edge communication and improves the overall performance of DDNN.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things big data information extraction, and more specifically relates to a DDNN based on cloud-edge collaborative computing and its construction method and application. Background technique [0002] Internet of Things (IoT) devices are deployed in complex environments, for example, sensors are geographically distributed and can acquire multi-view data of a target object. Therefore, the multi-camera sensor network can obtain information from different perspectives of the same object, and making full use of this data reflects the diversity and value of IoT big data. [0003] Deep learning is one of the most promising approaches to extract precise information from raw IoT big data. Distributed Deep Neural Network (DDNN) has a multi-layer structure, and the amount of calculation parameters increases exponentially with the increase of the number of network layers. The most prominent performance is...
