Problems solved by technology

[0004] When capturing a certain target in the detection area of ​​any radar, four calibration points need to be pre-configured, which makes the calibration work before the capture more cumbersome, which is not conducive to the promotion of the above capture method.

Embodiment Construction

[0079] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0080] figure 1 It is a schematic diagram of a lightning ball linkage system provided by the embodiment of this application. Such as figure 1 As shown, the thunderball linkage system 100 includes a ball machine 101 and a plurality of radars 102 . Each radar 102 is connected to the dome camera 101 in a wireless or wired manner for communication.

[0081] For any radar 102, if the radar detects a target in its own detection area, it can control the dome camera to adjust shooting parameters, so as to capture the target.

[0082] The capture method provided by the embodiment of the present application can be applied to any radar 102. At this time, when the radar 102 detects the target, it determines the PTZ coordinates of the targ...

Abstract

The invention discloses a snapshot method and device and a computer storage medium, and belongs to the field of intelligent security and protection. In the method disclosed in the invention, the corresponding relationship between the radar coordinates and the PTZ coordinates is determined according to the positioning coordinates of the first radar, the positioning coordinates of the dome camera, the positioning coordinates of one calibration point in the normal direction of the first radar and the PTZ coordinates when the dome camera shoots the first radar. Thus, before snapshot, only the plane coordinate of the first radar, the plane coordinate of the dome camera, the plane coordinate of one calibration point in the normal direction of the first radar and the PTZ coordinate of the first radar shot by the dome camera need to be acquired; there is no need to configure four calibration points in advance and determine the calibration radar coordinate and the calibration PTZ coordinate ofeach calibration point; calibration work before snapshot is simplified, and popularization of the snapshot method provided by the invention is facilitated.

Description

technical field [0001] The present application relates to the field of intelligent security technologies, in particular to a method, device and computer storage medium for capturing images. Background technique [0002] In the field of intelligent security technology, in order to track a certain target, the speed dome needs to adjust the PTZ coordinates, which include horizontal angle, pitch angle and magnification of the speed dome. For the dome camera, P (Pan, referred to as P) indicates the horizontal rotation angle of the dome camera, T (Tilt, referred to as T) indicates the vertical rotation angle of the dome camera, and Z (Zoom, referred to as Z) indicates the observation magnification of the dome camera. When the speed dome collects images according to the adjusted PTZ coordinates, the target can be placed at a suitable position in the shooting picture, so as to realize the capture of the target. [0003] In the related art, multiple radars are configured for the dom...
