and the searching module searches the cameras around the linked cameras to acquire real-time videos of the cameras around or position the cameras around to the linked points.
2. The device for linking 1+ N video cameras according to claim 1, wherein the coordinate acquisition module acquires the GPS coordinates of a point of the real-time video when the point is clicked with a mouse as the linked point.
3. The 1+ N camera-mechanical linkage device according to claim 2, wherein the coordinate acquisition module comprises:
the first acquisition module acquires XY coordinates of a screen of a real-time video;
a second obtaining module, configured to convert the XY coordinates into PT coordinates;
and the third acquisition module is used for converting the PT coordinates into GPS coordinates and acquiring the GPS coordinates of the mouse click point.
4. The 1+ N camera-mechanical linkage device according to claim 1, wherein the data processing module further comprises:
and the first data conversion module converts the GPS coordinate into a PT coordinate through the GPS coordinate acquired by the linked camera when the linked camera is identified as an AR dome camera by the identification module, acquires the PT coordinate of the linked camera, and then positions the linked camera to a linked point through the PT coordinate.
5. The device for linking 1+ N cameras according to claim 1, wherein the searching module automatically searches for the cameras around the linked cameras by using GPS coordinates.
6. The 1+ N camera-in-machine linkage device according to claim 5, wherein the search module is connected with the identification module,
the searching module acquires a real-time video through the video monitoring platform when the identification module identifies that the searched camera is a gunlock or a common ball machine;
when the identification module identifies that the searched camera is the AR dome camera, the search module converts the GPS coordinate into the PT coordinate through the GPS coordinate acquired by the linked camera, acquires the PT coordinate of the peripheral camera, and then positions the peripheral camera to the linked point through the PT coordinate.
7. The apparatus for linking 1+ N cameras according to claim 6, further comprising:
and the positioning module is used for zooming and stretching the focal length according to the visible distance between the AR dome camera and the target point and the type of the AR dome camera, so that accurate positioning is realized.
