Target tracking method and system based on two-stage convolutional neural network

Abstract

The invention relates to a target tracking method and system based on a two-stage convolutional neural network. The method comprises the following steps: acquiring a video stream in a detection area, and preprocessing the video stream to obtain multiple frames of pictures; inputting the plurality of frames of pictures into a pre-trained YOLOv3 target detection improved model for target detection to obtain a picture with a detection target frame; and carrying out detection target tracking on the frame picture with the detection target by utilizing a deepsort multi-target tracking algorithm, and tracking the real-time position of the detection target in the frame picture. According to the invention, the targets are monitored in real time by adopting the improved YOLOv3 and Deepsort multi-target tracking combined two-stage convolutional neural network, so that the real-time position information of the same moving object is obtained more accurately, the calculation errors of multiple targets and overlapped targets are avoided, the real-time tracking of the moving multi-target objects is realized, and the detection accuracy is high.

Description

technical field [0001] The invention relates to the field of parking detection, in particular to a target tracking method and system based on a two-stage convolutional neural network. Background technique [0002] Hazardous chemical transport vehicles, referred to as hazardous chemical vehicles, are extremely dangerous because their loading and unloading materials are usually flammable, explosive or highly toxic substances. Therefore, they must be parked at designated locations in strict accordance with the management measures for hazardous chemical vehicles. During transportation, it is not allowed to park at will, and temporary parking is not allowed near open flames, high-temperature places, crowded places and other places that may cause harm. In view of the problem that hazardous chemical vehicles may cause serious harm if they are not parked according to regulations during road transportation, especially in chemical industrial parks, [0003] At present, based on pure ...

Problems solved by technology

Since these four parts of loss are not independent of each other, there is an interdependence relationship in actual calculation, so there is a deviation in this loss calculation method, which cannot accurately reflect the actual loss caused by the center coordinates and width and height

For example, there may be different center abscissa, center ordinate, width and height losses while the total center coordinates and width and height losses are the same
