Problems solved by technology

[0006] However, manually drawing tripwires requires a lot of manual work and low efficiency. Each tripwire needs to be drawn manually, and the error caused by dragging the mouse in the video image is relatively large
In addition, not only does all the work need to be repeated for each camera, but also the unified tripwire drawn under multiple cameras cannot be automatically recognized, and it needs to be recoded one by one, and manual work is required for matching, which is a heavy workload and error-prone

Embodiment Construction

[0068] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0069] Tripwires are artificially drawn dotted lines on video images by users according to their own needs, which do not really exist. The meaning of tripwire detection is that when the system detects that a moving target crosses the tripwire, the system will send out an alarm.

[0070] The embodiment of the present invention provides a tripwire drawing method, such as figure 1 As shown, the tripwire drawing method includes:

[0071] S101: Set the same tripw...

Abstract

The invention provides a trip line drawing method and device. The trip line drawing method comprises the steps of arranging identical trip line markers at the positions of any two points on a determined trip line; obtaining an image comprising the two wire trip markers; and drawing a trip line according to the positions of the two trip line markers in the image. According to the embodiment of theinvention, the method and the device can achieve the recognition of the position of the trip line through coding, and achieve the automatic drawing of the trip line.

Description

technical field [0001] The present invention relates to video surveillance technology, in particular to a tripwire drawing method and device. Background technique [0002] With the rapid progress of society and the continuous enhancement of national strength, the demand for safety precautions and on-site recording and alarm systems in many fields is increasing day by day, and the requirements are also getting higher and higher, making video surveillance technology widely used in all aspects of production and life. The traditional digital video surveillance system only provides simple functions such as video capture, storage, and distribution. As the video information acquired by the system gradually increases, it is difficult for these massive video information to be displayed in front of the monitoring personnel at the same time, and the information judgment is still difficult. Relying on the subjective judgment of personnel, it is difficult to guarantee accuracy. [0003]...
