Focusing control method, control apparatus and control system, and storage medium

A focusing control apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, storing program instructions which, when executed by the processor, cause the processor to perform the method comprising:
• controlling a carrier platform carrying a display panel to move in a preset direction at a preset speed;
• controlling a distance measuring sensor to measure a first distance between the distance measuring sensor and a detection point, wherein the detection point is a point on a surface of the display panel located at a preset distance measuring position;
• adjusting a distance between an image acquiring device and the detection point based on the first distance in a case where the detection point reaches a preset image acquiring position in a field of view of the image acquiring device, such that the distance between the image acquiring device and the detection point is a focusing distance of the image acquiring device;
• and
• controlling the image acquiring device to acquire an image of the surface of the display panel.
