Target tracking method and apparatus and unmanned aerial vehicle

A target tracking apparatus, applicable to an unmanned aerial vehicle (UAV), the UAV comprising a visible light camera and an infrared camera, wherein the apparatus comprises:

• a memory, configured to store a computer-executable target tracking program;
• and
• a processor, configured to invoke the computer-executable target tracking program to implement:
• controlling the visible light camera to perform visual tracking on a target object, and recording first tracking information of the target object in real time, wherein the first tracking information comprises first location information of the target object;
• controlling the infrared camera to perform infrared tracking on the target object, and recording second tracking information of the target object in real time, wherein the second tracking information comprises second location information of the target object;
• controlling, in a case of determining that the target object is lost in the visible light camera, the visible light camera to re-lock the target object according to the second tracking information and continue to perform visual tracking;
• and
• controlling, in a case of determining that the target object is lost in the infrared camera, the infrared camera to re-lock the target object according to the first tracking information and continue to perform infrared tracking.

An unmanned aerial vehicle (UAV), comprising:

• a body;
• arms connected to the body;
• a visible light camera, disposed on the body;
• an infrared camera, disposed on the body;
• at least one processor, disposed on the body, wherein the processor is communicatively connected to the visible light camera and the infrared camera respectively;
• and
• a memory, communicatively connected to the processor, wherein
• the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor, to cause the at least one processor to perform:
• controlling the visible light camera to perform visual tracking on a target object, and recording first tracking information of the target object in real time, wherein the first tracking information comprises first location information of the target object;
• controlling the infrared camera to perform infrared tracking on the target object, and recording second tracking information of the target object in real time, wherein the second tracking information comprises second location information of the target object;
• in a case of determining that the target object is lost in the visible light camera,
• controlling the visible light camera to re-lock the target object according to the second tracking information and continue to perform visual tracking;
• or
• in a case of determining that the target object is lost in the infrared camera,
• controlling the infrared camera to re-lock the target object according to the first tracking information and continue to perform infrared tracking.

A non-transitory computer-readable storage medium, the non-transitory computer-readable storage medium storing computer-executable instructions, the computer-executable instructions being configured to enable an unmanned aerial vehicle (UAV) to perform:

• controlling the visible light camera to perform visual tracking on a target object, and recording first tracking information of the target object in real time, wherein the first tracking information comprises first location information of the target object;
• controlling the infrared camera to perform infrared tracking on the target object, and recording second tracking information of the target object in real time, wherein the second tracking information comprises second location information of the target object;
• in a case of determining that the target object is lost in the visible light camera,
• controlling the visible light camera to re-lock the target object according to the second tracking information and continue to perform visual tracking;
• or
• in a case of determining that the target object is lost in the infrared camera,
• controlling the infrared camera to re-lock the target object according to the first tracking information and continue to perform infrared tracking.
