Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0038] It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first camera could be termed a second camera, and, similarly, a second camera could be termed a first camera, without departing from the scope of the present application. Both the first camera and the second camera are cameras, but they are not the same camera.

Abstract

The invention relates to a depth map acquisition method, a device, electronic equipment and a computer readable storage medium. The method comprises the following steps: controlling a first camera to perform exposure, and obtaining a target brightness map according to brightness values of pixel points included in each pixel point group obtained by exposure; segmenting the target brightness image to obtain a first segmented brightness image and a second segmented brightness image, and determining the phase difference of mutually matched pixels in the first segmented brightness image and the second segmented brightness image; and determining depth information corresponding to the mutually matched pixels according to the phase difference of the mutually matched pixels, and generating a target depth map according to the depth information corresponding to the mutually matched pixels. In other words, it is not needed to turn on multiple cameras at the same time for image shooting to obtain the depth information, and power consumption during depth information obtaining can be reduced.

Description

technical field [0001] The present application relates to the field of image technology, in particular to a depth map acquisition method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the development of image technology, the application of image depth information is more and more extensive. For example, focusing, image blurring, and three-dimensional reconstruction can be performed according to the image depth information. At present, it is more common to configure two cameras with different positions on the electronic device, and determine the depth information of the captured object according to the parallax of the captured object in the images captured by the two cameras with different positions. [0003] However, the traditional way of acquiring depth information needs to turn on two cameras for shooting, which has the problem of high power consumption.
