The invention relates to a method for recognizing a human face and a license plate.
Usually in the process of traffic banning or criminal investigation, it often needs to confirm the identity of personnel and vehicles. Police officers need to input an identity card number or a license plate number input to an electronic device by a keyboard or simply through handwriting, and connected to a database for inquiries. Therefore since it spends a certain amount of time, the opportunity for handling the case is often missed.
An object of the invention is to provide a method for recognizing a human face and a license plate simultaneously. By capturing the image of a human face or license plate and identifying it, and then comparing it with human face data of the license plate data in a database, it can be know immediately whether the person or vehicle is the one been seeking.
The invention provides a method for recognizing a human face and a license plate simultaneously. The method in accordance with an exemplary embodiment of the invention includes providing a wearable device comprising an image capturing device; capturing an image through the image capturing device; determining whether a human face or a license plate is in the image; analyzing the human face or the license plate and generating recognized human face data or recognized license plate data when a human face or a license plate is in the image; comparing the recognized human face data or the recognized license plate data with a plurality of human face data and a plurality of license plate data saved in a database; and displaying the recognized human face data or the recognized license plate data when the recognized human face data or the recognized license plate data matches the human face data or the license plate data.
By utilizing the wearable device for recognizing a human face and a license plate of the invention, persons or vehicles in front of a user can be recognized immediately and determined whether it is the person or the vehicle been seeking. Therefore, it can be applied to traffic management and criminal investigation and so on.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
Referring to
In addition, the wearable device 100 further includes a control board 60 through which the image is transmitted to the central processing unit 40. The recognized human face data or the recognized license plate data are transmitted to the display unit 50 through the control board 60. The control board 60 includes an analog/digital converting unit. The analog images are converted to digital images by the analog/digital converting unit. The digital images are then transmitted to the central processing unit 40 for recognition and comparison. The recognized data matching the data in the database 30 are converted into analog image signals which are transmitted to the display unit 50 or analog audio signals which are transmitted to a speaker (not shown).
The wearable device 100 further includes a thermal sensing module 70 configured to capture the image and generate a thermal image. The display unit 50 includes a first display device 52 and a second display device 54. The image is transmitted to the first display device 52, and the thermal image is transmitted to the second display device 54. When the recognized human face data match the human face data or the recognized license plate data match the license plate data, the central processing unit 40 transmits the recognized human face data or recognized license plate data to the first display device 52 for displaying the recognized human face data or recognized license plate data.
The database 30 includes a local database 32 and a cloud database 34. The local database 32 is connected to the central processing unit 40, and the cloud database 34 is connected to the central processing unit 40 through a network. The network is a wireless network or a wired network. The human face data and the license plate data in the local database 32 are the same as the human face data and the license plate data in the cloud database 34. In another embodiment, the human face data and the license plate data in the local database 32 are different from the human face data and the license plate data in the cloud database 34.
The wearable device 100 further includes a power supply 80 connected to the central processing unit 40. In this embodiment, the power supply 80 is a battery. In another embodiment, the wearable device 100 further includes a power control board 90 connected to the central processing unit 40, and an external power supply is coupled to the central processing unit 40 via the power control board 90. The external power supply may provide power for the wearable device 100 or charge the power supply 80.
Referring to
By utilizing the wearable device for and the method for recognizing a human face and a license plate of the invention, persons or vehicles in front of a user can be recognized immediately and determined whether it is the person or the vehicle been seeking. Therefore, it can be applied to traffic management and criminal investigation and so on.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
