Embodiment Construction

[0036] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0037] Such as figure 1 Shown, a kind of face detection recognition method of the present invention comprises the following steps:

[0038] (1) Obtain two face images through the binocular camera. When acquiring the image, the face should be facing the binocular camera as possible, so as to obtain a more reliable face image. The resolution of the camera should be no less than 5 million pixels, so as to obtain more accurate facial feature point positions. The distance between the face and the camera should ensure that the face occupies as much photo area as possible.

[0039] (2) After obtaining the left and right images, use the improved version of the P_Net network to calculate the input, such as figure 2 As shown, the input size is set to 1202×1202×3, the second layer network is set to 600×600×10, the pooling layer is a 2×2 matrix, the thi...

Abstract

The invention discloses a face detection and recognition method based on binocular vision. The method comprises the following steps: (1) acquiring left and right face pictures through a binocular camera; (2) detecting two pictures through hog features, and finding out two corresponding face pictures from the two pictures; (3) extracting human face features from the two acquired pictures containingthe human faces; (4) obtaining face feature point depth information through a binocular vision distance measurement method so as to calculate a face three-dimensional model; (5) analyzing a calculated result by using a statistical method to realize identification. Specifically, a support vector machine is used to classify a three-dimensional face model so as to realize face recognition. Face detection and three-dimensional reconstruction and recognition are achieved through the shooting, detection, modeling and classification technologies, and the method has the advantages of being efficientand rapid in processing, safe, reliable and capable of providing more complete and richer detection information.

Description

technical field [0001] The invention belongs to the technical field of digital image processing, and in particular relates to a face detection and recognition method based on binocular vision. Background technique [0002] Since 2001, the public security department has begun to use face detection technology to prevent and crack down on major criminal crimes and obtain the support of the state. In 2008, when the Beijing Olympic Games was held, the face detection technology was applied, which marked that the face detection in our country entered the practical stage. Since then, at the Shanghai World Expo, this technology has been more widely used, and at the same time, major companies have also joined in, which has accelerated the large-scale application of face detection technology in China. With the domestic technological progress in this field, "three modernizations and two integrations" will be an inevitable trend in the development of face detection technology. Among th...
