Problems solved by technology

However, due to the complex motion of the object to be tracked in the image frame, for example, the size and position of the object to be tracked are changing, it is difficult to accurately determine the object to be tracked from each moving object, that is, when the object to be tracked is tracked is not accurate enough

Embodiment approach

[0126] Method 1: According to the area of ​​the object to be tracked in the image frame to be tracked and the preset designated area in the image to be tracked, adjust the orientation of the image acquisition device that collects the image frame to be tracked to move the image acquisition range of the image acquisition device .

[0127] Wherein, the specified area may be an area centered on the center point of the image to be tracked. When adjusting the orientation of the image acquisition device, it may include: adjusting the rotation of the image acquisition device in the horizontal direction, and / or adjusting the rotation of the image acquisition device in the vertical direction.

[0128] According to the area of ​​the object to be tracked in the image frame to be tracked, and the preset specified area in the image to be tracked, when adjusting the orientation of the image acquisition device that collects the image frame to be tracked, it can be specifically determined that...

Abstract

The embodiment of the invention provides an object tracking method and system. The method comprises the steps of obtaining a to-be-tracked image frame, and obtaining a target object attribute of a to-be-tracked object; determining an object region and a corresponding object attribute in the to-be-tracked image frame; matching the target object attribute with the object attribute; and when matchingsucceeds, determining the area of the to-be-tracked object in the to-be-tracked image frame according to the object area corresponding to the object attribute. By applying the scheme provided by theembodiment of the invention, the accuracy of tracking the to-be-tracked object can be improved.

Description

technical field [0001] The present application relates to the technical field of monitoring, in particular to an object tracking method and system. Background technique [0002] In the field of video surveillance applications, it is often necessary to detect objects to be tracked from surveillance videos, such as vehicles to be tracked, people to be tracked, and the like. The device can detect a moving object in a moving state from the image frame of the surveillance video according to the mobility of the object to be tracked, and determine the object to be tracked from the moving object according to the area of ​​the object to be tracked in the previous image frame. However, due to the complex motion of the object to be tracked in the image frame, for example, the size and position of the object to be tracked are changing, it is difficult to accurately determine the object to be tracked from each moving object, that is, when the object to be tracked is tracked The accuracy...
