Abstract

The invention discloses an image returning method of internet of things nodes; the image returning method comprises the following steps: returning a previous frame image to an internet of things server; obtaining a present frame image and the acquisition time of the same; calculating the similarity between the present frame image and the previous frame image; determining whether the similarity is bigger than or equal to a preset threshold; if the similarity is >= the preset threshold, sending a first inform order to the server, thus allowing the server to use the previous frame image as the image collected at the acquisition time of the present frame image; if the similarity is < the preset threshold, returning the present frame image to the server. In addition, the invention also discloses an image storage method of the internet of things server, internet of things nodes, and the internet of things server. The image returning method, the image storage method, the internet of things node and server can greatly reduce the returning data amount, thus reducing system occupied resources, and reducing the system burden.

Description

technical field [0001] The invention relates to the Internet of Things technology, in particular to an image return method, an image storage method, a node and a server of the Internet of Things. Background technique [0002] The Internet of Things has been widely used, and it is even possible to capture and return images. However, the data volume of the image is relatively large, and returning the image will occupy system resources and increase the burden on the system. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide an image return method, an image storage method, a node and a server of the Internet of Things. [0004] The image return method of the node of the Internet of Things in the embodiment of the present invention comprises the following steps: [0005] Return the previous frame image to the server of the Internet of Things...
