Gun and ball linkage method, calibration method and device

The invention discloses a gun-dome camera linkage method, a calibration method and a calibration device, relates to the technical field of video monitoring and the technical field of thermal imaging, and can realize automatic calibration between a gun camera and a dome camera. The method comprises the following steps: acquiring pixel coordinates of a target object in a target thermal imaging image acquired by a thermal imaging image acquisition device in the target thermal imaging image; converting the pixel coordinates into PTZ coordinates of the target object according to the target conversion relation; the target conversion relation is a coordinate conversion relation between coordinates of pixels in a thermal imaging image acquired by the thermal imaging image acquisition device and PTZ coordinates of the dome camera; according to the PTZ coordinate of the target object, adjusting the dome camera to a specified state; wherein the specified state is the state of the dome camera when the target object is lo
