Title:

DEPTH INFORMATION ACQUISITION METHOD AND APPARATUS, AND IMAGE COLLECTION DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/120771

Kind Code:

A1

Abstract:

A depth information acquisition method and apparatus, and an image collection device. The image collection device comprises a first camera and a second camera. The method comprises: a depth information acquisition apparatus being capable of acquiring images respectively collected by the first camera and the second camera when shaking is detected (S201), detecting an initial distance of a target shot object in the two images (S202), then correcting the initial distance by using an offset difference value between the first image and the second image (S204), and determining the depth of the target shot object by using the corrected initial distance (S205). The two cameras can both have an OIS function, or only one camera has the OIS function, and when OIS is performed, the depth information acquisition apparatus may correct the distance between the same shot object in images respectively acquired by the two cameras so as to make the finally obtained depth information more precise, so that the shot object can be focused precisely and rapidly.
