Target Monitoring Method, Camera, Controller, and Target Monitoring System

A first camera, wherein the first camera is comprised in a target monitoring system, wherein the target monitoring system comprises the first camera and a second camera, and wherein the first camera comprises:

• a memory comprising instructions:
• and
• a processor coupled to the memory, wherein the instructions cause the processor to be configured to:
• obtain location information of a target in a first monitoring picture when the first camera is used as a current primary monitoring camera, wherein the first monitoring picture is captured by the first camera;
• determine, based on the location information of the target in the first monitoring picture, whether a location of the target in the first monitoring picture is in an overlapping area, wherein the overlapping area is an overlapping range between a field of view of the first camera and a field of view of the second camera;
• and
• switch the current primary monitoring camera to the second camera when the location of the target in the first monitoring picture is in the overlapping area.

A controller, wherein the controller is deployed in a target monitoring system comprising the controller, a first camera, and a second camera, and wherein the controller comprises:

• a memory comprising instructions;
• and
• a processor coupled to the memory, wherein the instructions cause the processor to be configured to:
• obtain location information of a target in a first monitoring picture when the first camera is used as a current primary monitoring camera, wherein the first monitoring picture is from the first camera;
• determine, based on the location information of the target in the first monitoring picture, whether a location of the target in the first monitoring picture is in an overlapping area, wherein the overlapping area is an overlapping range between a field of view of the first camera and a field of view of the second camera;
• and
• switch the current primary monitoring camera to the second camera when the location of the target in the first monitoring picture is in the overlapping area.
