Embodiment Construction

[0023] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] In various fields such as face payment, somatosensory games, and AR shopping, it is necessary to obtain the depth information of the image. For example, in the field of face payment, it is necessary to obtain the depth information of the face in the face image to accurately match whether the face for payment verification is the registered face.

[0025] Monocular speckle measurement can be used as a method to obtain image depth information. Generally, monocular speckle measurement methods can be divided into temporal correlation and spatial correlation. Time correlation generally refers to moving an equidistant reference curtain in a space of known depth, the em...

Abstract

The invention discloses a speckle-based depth information acquisition method, device and system, and relates to the technical field of image processing. The method comprises the following steps: acquiring a target speckle image, template windows respectively corresponding to M template images, and a virtual optical center of a projection unit obtained based on the template windows respectively corresponding to the M template images, and acquiring second pixel points respectively corresponding to N first pixel points in the target speckle image from at least one template image, and obtaining depth information of the first pixel points according to the positions of the first pixel points in the target speckle image, the positions of the second pixel points in the corresponding template images and the positions of the virtual optical centers, thereby obtaining the depth information of the target speckle image and improving the obtaining efficiency of the depth information of the target speckle image.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a method, device and system for acquiring depth information based on speckle. Background technique [0002] With the development of science and technology, in some image display scenarios, two-dimensional images can no longer meet people's needs. Three-dimensional images are more real and accurate because they have more depth information than two-dimensional images. In daily life, the use of three-dimensional scenes is becoming more and more common, such as face payment, somatosensory games, AR shopping, etc. [0003] In a three-dimensional scene, it is necessary to obtain the depth information of the image, but the existing methods for obtaining the depth information of the image require a large amount of calculation and time-consuming calculation. Contents of the invention [0004] In view of the above problems, the present application proposes a ...
