Embodiment Construction

[0022] 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.

[0023] 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.

[0024] 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 depth information detection method and device and electronic equipment, and relates to the technical field of image processing. The method comprises the following steps: obtaining a target speckle image group formed by projecting k different reference speckle patterns to a target object; and respectively matching the m coarse matching template groups with all or part of the target speckle image group, and obtaining the coarse matching template group with the highest similarity as a primary matching template group, wherein the interval between every two adjacent coarsematching template groups is R, the interval between every two adjacent fine matching template groups is r, and R is greater than r; selecting fine matching template groups within a preset range before and after the primary matching template group, respectively matching the fine matching template groups with all or part of the target speckle image group, and obtaining the fine matching template group with the highest similarity as a secondary matching template group; and determining depth information of the target speckle image according to the depth information of the secondary matching template group.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a depth information detection method, device and electronic equipment. 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 depth i...
