Embodiment

[0087] A method for automatically positioning coordinates of a scene in a real-time video in this embodiment includes the following steps:

[0088] The first step is to obtain PTZ parameters, such as figure 1 shown.

[0089] PTZ represents the omnidirectional coordinates of the pan / tilt. Among the PTZ parameters, PTZ(X): the horizontal orientation of the pan / tilt; PTZ (Y): the vertical orientation of the pan / tilt; PTZ (P): the multiple of the lens; Realize the horizontal rotation, vertical rotation, lens zoom and lens zoom control of the dome camera or PTZ camera.

[0090] One way to obtain PTZ parameters is to obtain them from the SDK of the dome camera or PTZ camera.

[0091] Another way to obtain PTZ parameters is: each time the dome camera or PTZ camera is restarted, set an initial PTZ for the dome camera or PTZ camera and save it, obtain the PTZ parameters, and when the dome camera or PTZ camera During horizontal rotation, vertical rotation, lens zoom and lens zoom, th...

Abstract

The invention discloses a method for automatically positioning the coordinate of the scene in a real-time video. The method comprises the steps that S1, PTZ (pan / tilt / zoom) parameters are acquired; S2, the coordinate of a video displaying area is determined, the scene needing to be acquired serves as a reference substance and manually calibrated, and the coordinate of the reference substance is acquired; S3, the step A and the step B are conducted simultaneously according to the acquired PTZ parameters, in specific, A, the matching relation of PTZ operation conducted on a ballhead camera or aPTZ camera and the scene coordinate in the screen is calculated, and the scene coordinate in the screen video is determined, marked and stored; and B, the matching relation of PTZ operation conductedon the ballhead camera or the PTZ camera and the screen coordinate is calculated, and the real-time video displaying area in the screen is determined; and S4, the scene coordinate in the screen videois marked and displayed. The method achieves the video structuralizing of the scene position I the real-time video; is convenient for conducting rapid searching on the scene position in massive videos; and only conducts processing on the coordinate data, occupies less hardware sources, is convenient for processing of massive videos, is not affected by the image quality and the light conditions, and the precision is high.

Description

technical field [0001] The invention belongs to the fields of information technology and automation technology, and in particular relates to a method for automatically positioning coordinates of a scene in a real-time video. Background technique [0002] Video object localization includes object localization based on contrast analysis, object localization based on matching and object localization based on motion detection. [0003] Target positioning based on contrast analysis: It mainly uses the contrast difference between the target and the background to realize the detection and positioning of the target. [0004] Target positioning based on matching: Target positioning is mainly achieved through feature matching between the front and rear frames. Features are the properties of objects that can be distinguished from other things, and have the characteristics of distinguishability, reliability, independence and sparsity. Matching-based object localization algorithms need...
