Abstract

An auto-focus method including at a same moment, collecting a first image of a first object using a first image shooting unit, collecting a second image of the first object using a second image shooting unit, calculating M pieces of first depth information of M same feature point pairs in corresponding areas in the first image and the second image, determining whether confidence of the M pieces of first depth information is greater than a threshold, obtaining focusing depth information according to N pieces of first depth information in the IM pieces of first depth information when the confidence of the M pieces of first depth information is greater than the threshold, obtaining a target position of a first lens of the first image shooting unit according to the focusing depth information, and controlling the first lens to move to the target position.
