Camera Focusing Method, Apparatus, and Device for Terminal

A camera focusing device for a terminal, comprising:

• an interface circuit configured to obtain a first confidence and a second confidence, the first confidence comprising a confidence of an object distance obtained by measurement in a laser ranging manner, the second confidence comprising a confidence of an object distance obtained by measurement in a binocular ranging manner, a confidence indicating accuracy of an object distance obtained by measurement in a ranging manner, the terminal comprising a laser sensor, a first camera, and a second camera, and the first camera and the second camera being disposed side by side;
• and
• a processor coupled to the interface circuit and configured to:
• determine a target ranging manner and a target object distance when the first confidence and the second confidence obtained by the interface circuit meet a preset condition, the preset condition comprising that the first confidence is greater than a first confidence threshold or the second confidence is greater than a second confidence threshold, and the target ranging manner comprising the laser ranging manner or the binocular ranging manner;
• determine a target position in a lens position interval;
• and
• assist the first camera and the second camera to complete focusing based on the target position in the lens position interval.

A computer program product comprising a readable storage medium configured to store a computer program code, the computer program code running on a processor, and the computer program code causing the processor to be configured to:

• obtain a first confidence and a second confidence, the first confidence comprising a confidence of an object distance obtained by measurement in a laser ranging manner, the second confidence comprising a confidence of an object distance obtained by measurement in a binocular ranging manner, and a confidence indicating accuracy of an object distance obtained by measurement in a ranging manner;
• determine a target ranging manner and a target object distance when the first confidence and the second confidence meet a preset condition, the preset condition comprises that the first confidence is greater than a first confidence threshold or the second confidence is greater than a second confidence threshold, and the target ranging manner comprising the laser ranging manner or the binocular ranging manner;
• determine a target position in a lens position interval;
• and
• assist a first camera and a second camera to complete focusing based on the target position in the lens position interval, the first camera and the second camera being disposed side by side on a terminal, and the terminal further comprising a laser sensor.
