Abstract

The invention relates to a moving target identification method comprising the following steps: after a video image sequence is obtained, a moving object of the video image sequence is detected, the moving object is tracked, and a movement track of the moving object is obtained; according to the movement track of the moving object, characteristic information of the moving object is extracted, the characteristic information of the moving object is input into a decision tree model, the characteristic information of the moving object is subjected to decision making operation via nodes of the decision tree model, and therefore the moving object is identified; the nodes of the decision tree model are used for recording moving object identification criteria corresponding to the characteristic information of the moving object. The moving target identification method is used for overcoming defects that conventional technology-based identification is low in accuracy, technical effects that the moving object can be accurately identified can be exerted, and data support is provided for video monitoring of the object. The invention also provides a moving target identification system, and a bicycle flow statistics method and device.

Description

technical field

[0001] The invention relates to the technical field of identification, in particular to a method and system for identifying a moving object, and a method and device for counting bicycle traffic. Background technique

[0002] With the development of technologies such as video surveillance, the requirements for the accuracy of identifying moving objects in the video are getting higher and higher. Taking the traffic target of road traffic as an example, unreasonable planning of road traffic resources will lead to problems such as road traffic congestion. The rational planning of road traffic resources depends on the accurate identification of traffic targets of road traffic, such as the sharp increase in the number of road bicycles Occupy a lot of road traffic resources, reasonable planning of road traffic resources.

[0003] The traditional technology obtains the image feature information of the moving object in the video image by extracting the foreground ima...

Embodiment Construction

[0042] The specific implementation of the moving object recognition method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] In one embodiment, a moving target recognition method is provided, referring to figure 1 said, figure 1 It is a flow chart of the moving target recognition method in one embodiment of the present invention, including the following steps:

[0044] Step S102, after acquiring the video image sequence, detecting a moving target in the video image sequence.

[0045] Wherein, each frame of the video image sequence includes a background of the image and a moving target in the image, and by detecting the moving target in the image under the background of the image, the moving target of each image in the video image sequence is obtained.

[0046] The video image sequence may be a video containing vehicle traffic information, and the moving object may be a moving traffic object, such as a single bi...
