Embodiment Construction

[0031] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings. Embodiment: a kind of portrait acquisition method applying binocular recognition in this embodiment, such as figure 1 shown, including the following steps:

[0032] S1 collects different lighting images P through two cameras Xn and image P Yn ; The relative position between the two cameras remains fixed. The two cameras remain relatively fixed, that is, the distance between the two cameras remains unchanged, so that the captured image format remains consistent, ensuring uniform standards and facilitating identification.

[0033] S2 for different illumination images P Xn and image P Yn Perform illumination normalization processing, and construct an illumination reference image P' Xn and image P′ Yn ; Illumination normalization processing specifically includes:

[0034] S2.1 Input Image P Xn (x X...

Abstract

The invention discloses a portrait acquisition method applying binocular recognition. The portrait acquisition method comprises the following steps: acquiring different illumination images PXn and PYn through two cameras; carrying out the illumination normalization processing on the different illumination images PXn and PYn, and constructing an illumination reference image PX'n and an image PY'n; carrying out preprocessing and cognitive determination on the image PX'n and the image PY'n, and confirming the targeted cognitive features of the collected object based on the deep learning cognitive features of the images; carrying out parallax calculation according to a binocular stereo imaging principle and obtaining a point cloud picture; constructing a three-dimensional coordinate space according to the targeted cognitive features of the collected object and the point cloud atlas; and judging the recognition degree precision requirement and the error requirement of the three-dimensional coordinate space. According to the technical scheme, distance measurement is carried out through the parallax of the images collected by the binocular camera, and the collected images are standardized and unified in judgment by combining the depth camera with illumination compensation, so that accurate and rapid portrait recognition is realized.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a portrait acquisition method using binocular recognition. Background technique [0002] The identity authentication based on the face image aims to make the computer have the function of identifying the identity through the face. It is an intelligent system based on high technologies such as image understanding, pattern recognition, computer vision and neural network, which can partially or even completely replace human beings in complex and frequent identification work based on face images. Due to its wide range of application fields, face recognition technology has received extensive attention and research in the past three decades, and is being promoted to applications. [0003] According to data, face recognition has been widely used in various fields for security verification, including the verification of real-name information of users by various mobile phone ap...
