Abstract
The utility model discloses a kind of face identification device and mobile terminals.The face identification device includes：RGB cameras, the RGB image for obtaining face；Thermal imaging camera, the thermal infrared images for obtaining face；Primary processor is electrically connected between the RGB cameras and thermal imaging camera by ISP processors respectively for carrying out recognition of face according to the RGB image and thermal infrared images that obtain.The face identification device assists carrying out recognition of face using thermal imaging, and security performance is higher.
Description
Technical field
The utility model is related to field of face identification more particularly to face identification devices and mobile terminal.
Background technology
Face recognition technology is just being increasingly being applied on the mobile terminals such as mobile phone, still, for reasons of cost and skill
Art difficulty, on mobile terminal or based on the 2D face recognition schemes of single RGB cameras, this 2D face recognition schemes are only adopted
With simple image recognition technology, that is to say, that a high definition face is according to the camera that can out-trick completely, to crack this 2D people
Face identifying schemes, security performance are extremely low.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, a kind of face identification device of the utility model offer and mobile terminal.
The face identification device assists carrying out recognition of face using thermal imaging, and security performance is higher.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of face identification device, including：
RGB cameras, the RGB image for obtaining face；
Thermal imaging camera, the thermal infrared images for obtaining face；
Primary processor, for according to obtain RGB image and thermal infrared images carry out recognition of face, respectively with the RGB
It is electrically connected by ISP processors between camera and thermal imaging camera.
Further, the thermal imaging camera includes Nie Feier lens, Nie Feier lens setting the heat at
As camera is on optical channel.
Further, the Nie Feier lens are arranged on the photosurface of the thermal imaging chip of the thermal imaging camera.
Further, the primary processor respectively between the RGB cameras and thermal imaging camera by image at
Device is managed to be electrically connected.
A kind of mobile terminal, including above-mentioned face identification device.
Further, further include screen.
Further, the RGB cameras and thermal imaging camera are coplanar with the screen.
Further, the primary processor is the central processing unit of the mobile terminal.
The utility model has the advantages that：The face identification device is using RGB cameras+thermal imaging camera
It is double to take the photograph identifying schemes, it assists carrying out recognition of face using thermal imaging, when thermal imaging camera acquisition is red less than heat
When facial contour in the RGB image of outer image or facial contour and acquisition in the thermal infrared images of acquisition is inconsistent, then
Recognition of face does not pass through, and " deception " that high definition face can be avoided to shine, security performance is higher.
Description of the drawings
Fig. 1 is the functional block diagram of face identification device provided by the utility model；
Fig. 2 is the schematic diagram of mobile terminal provided by the utility model.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As shown in Figure 1, a kind of face identification device, including：
RGB cameras, the RGB image for obtaining face；
Thermal imaging camera, the thermal infrared images for obtaining face；
Primary processor, for according to obtain RGB image and thermal infrared images carry out recognition of face, respectively with the RGB
It is electrically connected by ISP processors between camera and thermal imaging camera.
The face identification device takes the photograph identifying schemes using the double of RGB cameras+thermal imaging camera, utilizes thermal imaging
Come assist carry out recognition of face, when the thermal imaging camera obtain less than in thermal infrared images or the thermal infrared images of acquisition
Facial contour and acquisition RGB image in facial contour it is inconsistent when, then recognition of face does not pass through, and can avoid high definition people
" deception " that face shines, security performance is higher.
When specifically used, the RGB cameras and thermal imaging camera obtain the RGB image and thermal infrared of face respectively
Image, the image algorithm in the primary processor carry out analysis and comparison, only RGB image to RGB image and thermal infrared images
In face information it is identical as preset face information, and in the facial contour in thermal infrared images and preset or RGB image
Facial contour it is identical, recognition of face just passes through.
In addition, at the night of dark, then the thermal imaging camera is can be used alone to carry out recognition of face, if
Facial contour in thermal infrared images is identical as preset facial contour, and recognition of face passes through.
The thermal imaging camera includes Nie Feier lens and thermal imaging chip, and the Nie Feier lens are arranged in the heat
Imaging camera head on optical channel, be preferably provided on the photosurface of the thermal imaging chip.
In order to improve image processing speed and precision, which further includes image processor, the main process task
Device is electrically connected between the RGB cameras and thermal imaging camera by image processor respectively.
Embodiment two
As shown in Fig. 2, a kind of mobile terminal, including the face identification device described in embodiment one and screen 1, it is described
RGB cameras 2 and thermal imaging camera 3 are coplanar with the screen 1.
The primary processor is the central processing unit of the mobile terminal.
The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot it therefore be interpreted as the limitation to the utility model patent range, as long as using the form institute of equivalent substitution or equivalent transformation
The technical solution of acquisition, shall fall within the scope of the present invention.
