A depth information acquisition method, device and image acquisition equipment

Abstract

A depth information acquisition method, device, and image acquisition device, wherein the image acquisition device includes a first camera and a second camera, and the depth information acquisition device can acquire images collected by the first camera and the second camera when shaking is detected (S201), and detect the initial distance of the target object in the two images (S202), then use the offset difference between the first image and the second image to correct the initial distance (S204), and use the corrected initial distance to determine The depth of the target object (S205). Both cameras can have OIS function, or one camera can have OIS function. When performing OIS, the depth information acquisition device will correct the distance of the same subject in the images acquired by the two cameras, so that the final obtained depth information is more accurate. , so as to accurately and quickly achieve focusing on the subject.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a depth information acquisition method, device image acquisition equipment. Background technique [0002] In the field of electronic technology, depth information refers to information related to the vertical distance between a lens (Lens) of a camera module in an image acquisition device and an object to be photographed. After obtaining the depth information, the camera module can control the movement of the lens according to the depth information, so as to realize the focus on the shooting object. Therefore, the accuracy of focusing depends on the accuracy of the depth information acquisition. Optical Image Stabilization (OIS) is a technology that relies on special lenses and photosensitive elements to minimize image instability caused by shaking during use by the operator. OIS is mainly realized by moving the lens. [0003] At present, people have higher and higher requir...

Problems solved by technology

In the prior art, the focal length of each camera module lens of an image acquisition device with multi-camera modules may be slightly different, so when the image acquisition device performs OIS, under the same jitter, the focal length of each camera module lens The shifting will be inconsistent, which will lead to inaccurate depth information finally obtained by the image acquisition device, making the accuracy of the image acquisition device in the focusing process low and slow
