Abstract

The embodiment of the invention provides an edge cooperative target detection method and device based on RoI coding, and the method comprises the steps: dividing a current video frame into a pluralityof region blocks, and carrying out the RoI coding of each region block, wherein the QP value for encoding the region block containing the target is smaller than a first preset threshold value, the QPvalue for encoding the region block not containing the target is larger than a second preset threshold value, and the target is a target detected by an edge end from a previous video frame of a current video frame; and enabling the equipment end to send the coded current video frame to the edge end, so that the edge end performs target detection on the coded current video frame based on a first target detection model. According to the embodiment of the invention, the transmission delay of transmitting the video frame from the equipment end to the edge end for target detection is reduced, so that the precision of real-time target detection is improved.

Description

Technical field[0001]The present invention relates to the technical field of target detection, in particular to an edge cooperative target detection method and device based on RoI coding.Background technique[0002]With the development of technologies such as the Internet of Things, wireless sensing and networking, smart phones, smart home appliances, AR (Augmented Reality) devices, and smart watches are becoming more and more popular, and cloud computing models that centrally process data are no longer sufficient The scenario of the Internet of Everything needs. The amount of data generated by various devices at the edge of the network is increasing, and the linear growth of cloud computing power cannot match the nearly exponential growth of massive edge data. At the same time, the large-scale data transmission of mobile devices to the cloud server will increase the network burden and cause long-term delay, which is not suitable for some applications with high real-time requirements....
