Drawings
FIG. 1 is a block diagram of the present invention
In the figure: the system comprises a near infrared light source 1, an infrared filter 2, a digital image imaging device 3, a power supply module 4, a USB interface 5, a motor 6, a shell 7 and a terminal display device 8.
Detailed Description
The present invention will be further explained with reference to the drawings and the embodiments.
Referring to fig. 1, the present embodiment provides a portable skin surface vein display apparatus, which includes a near-infrared light source 1, an infrared filter 2, a digital image imaging device 3, a power module 4, a USB interface 5, and a housing 7; the near-infrared light source 1 and the digital image imaging device 3 are arranged on the same plane of the shell; the infrared filter 2 is arranged at the front end of the digital image imaging device 3; the digital image imaging device 3 is connected with a USB interface 5 arranged on a shell 7; the USB interface 5 is used for connecting a terminal display device 8; the power module 4 is respectively connected with the near-infrared light source 1, the digital image imaging device 3 and the motor 6 and provides power.
The near-infrared light source 1 emits near-infrared light to the skin 9, the near-infrared light enters the digital image imaging device 3 after being reflected, and the vein has strong absorption to the infrared light, and other tissues generate strong scattering and weak absorption to the light; the digital image imaging device 3 captures the reflected or scattered near infrared light and transmits the near infrared light to the mobile phone terminal 8 for processing, so as to obtain the specific position of the blood vessel.
In this embodiment, a motor 6 is further provided to be connected to the infrared filter 2, the motor 6 drives the infrared filter 2 to rotate, when the infrared filter 2 rotates to the outside of the lens of the digital image imaging device 3, the collected skin original image formed by reflecting natural light can be collected, when the infrared filter 2 rotates to the lower side of the digital image imaging device 3, only infrared light can enter the digital imaging device 3 through filtering, and the collected infrared image enters the mobile phone terminal 8 to be further processed to obtain a blood vessel image. In the embodiment, the skin original image and the blood vessel image can be obtained, and the superposed image can be obtained through simple image processing of the mobile phone terminal, so that accurate blood vessel display is realized.
In this embodiment, the digital image imaging device 3 employs a CCD image sensor or a CMOS image sensor.
In this embodiment, the infrared light source 1 is L ED light source with wavelength of 760nm-850 nm.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
