Problems solved by technology

[0003] The existing face image collection is often realized by a single camera based on a fixed position. In this way, the viewing angle range is fixed. For users of different heights, it is impossible to ensure that the complete face image information is collected, which is prone to misidentification. even unrecognized cases

Embodiment Construction

[0037] Embodiments of the present invention provide an image acquisition device and method for acquiring complete face images of users of different heights.

[0038] refer to figure 1 , which is a schematic structural diagram of an image acquisition device provided by an embodiment of the present invention. The image acquisition device includes a first camera 101 and a second camera 102. The first camera 101 is used to acquire a face image; the second camera 102 is used to acquire a face image. Such as figure 1 As shown, the first camera 101 and the second camera 102 are vertically arranged up and down. Wherein, the first camera and the second camera may or may not be located on the same vertical plane, which is not specifically limited in this embodiment of the present invention.

[0039] When the image acquisition device captures a face image, in the image acquisition area 104, the field of view of the first camera 101 and the field of view of the second camera 102 includ...

Abstract

The embodiment of the invention discloses an image obtaining device and method that are used for obtaining complete face images of users with different heights. The image obtaining device comprises a first camera for obtaining a face image and a second camera for obtaining a face image; and the first camera and the second camera are arranged up and down along a vertical direction. In an image acquisition region, a view range of the first camera and a view range of the second camera include a view overlapped region along the vertical direction; and the height of the view overlapped region along the vertical direction is larger than a preset face length. On the basis of cooperation of the cameras, images of faces of users with different heights are obtained easily. Because the height of the view overlapped region is larger than the preset face length, when the overall face or the part of face of the user is located in the view overlapped region, at least one of the first camera and the second camera is capable of obtaining a complete face image, so that the image obtaining device is suitable for users with different heights.

Description

technical field [0001] The present invention relates to the image field, in particular to an image acquisition device and method. Background technique [0002] With the development of information and network technology, facial recognition technology has been highly praised by all walks of life due to its fast recognition speed, non-contact, accurate and convenient features, and is widely used in building intercom systems, security verification systems, driver's licenses and passports. Aspects such as authentication and criminal identification. [0003] The existing face image collection is often realized by a single camera based on a fixed position. In this way, the viewing angle range is fixed. For users of different heights, it is impossible to ensure that the complete face image information is collected, which is prone to misidentification. Even unrecognized cases. Contents of the invention [0004] Embodiments of the present invention provide an image acquisition dev...
