Problems solved by technology
The complex multi-camera face acquisition system can be divided into non-movable and mobile. The non-movable system is difficult to disassemble and poor in portability, and cannot realize remote collection; although the mobile system is highly portable, it has a single function, versatility and scalability poor sex
In addition, none of them can fully cover the perspective of the face, and the face data is not rich enough.

Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] see Figure 1-4 As shown, a multi-view reconfigurable face data acquisition system includes:
[0027] Hemispherical bracket 9, camera 3, light source 10, background 11, seat 5 and control subsystem 8, said bracket 9 includes semicircular bracket layer 1 supporting camera 3, bottom bracket, strut layer 2 and peripheral For the legs 4, the support layer 1 is divided into first to sixth support layers, and the strut layer 2 is divided into first to sixth strut layers. The cameras 3 are divided into six layers, and each layer of cameras 3 is installed on a corresponding support layer, and all cameras 3 are connected to computers through interfaces. The light source 10 is distrib...

The invention discloses a multi-view reconfigurable face data acquisition system, which includes a background cloth, a seat and a hemispherical support, and the hemispherical support includes six support layers arranged according to the latitude line and six support layers arranged according to the warp line. Six strut layers, each layer of support layer is evenly equipped with a predetermined number of cameras, the cameras are connected to the computer through the interface; it also includes a plurality of light sources, distributed in multiple positions centered on the ball of the support, the cameras and The light sources are all connected to the computer through a control subsystem, and the control subsystem is used to control all the cameras to synchronously capture omni-directional face images and the cycle action of the light source. The present invention has a variety of photos, the number of light sources can be adjusted and replaced independently, the background can be adjusted, and the full coverage of the human face is realized through the alignment.
Description
technical field [0001] The invention relates to the technical field of face data collection, in particular to a multi-view reconfigurable face data collection system. Background technique [0002] In recent years, biometric technology has played an important role in identity authentication, maintaining national security, personal information security, aviation security, relief supplies distribution and medical treatment, and its applications are becoming more and more extensive. Compared with fingerprint recognition, iris recognition, speech recognition and other biometric recognition technologies, face recognition has the advantages of naturalness and imperceptibility. It is widely used because of its high detection rate, high adaptability and convenient collection. [0003] Face recognition needs to use stable facial features, and the corresponding algorithms are based on methods such as LDA and PCA. With the continuous optimization and improvement of face recognition alg...
