Detailed description of the invention
Embodiment
As shown in Figure 1, a kind of vein imaging system, for the vein profile of organism is shown in the form of images, described vein imaging system comprises controller 10, and the Superficial veins imaging device to be connected respectively at controller 10 and deep vein imaging device, described controller 10 is for controlling the operation of Superficial veins imaging device and deep vein imaging device.The image of Superficial veins can be seen, the vein imaging of deep vein can be seen again.
Superficial veins imaging device comprise all be electrically connected with controller 10 the first infraluminescence source 1, video camera 3 and image-forming module 4; Described first infraluminescence source 1 is arranged on the below of camera lens, for launching infrared light to organism; Described camera lens receives the infrared light of organism reflection; Described image-forming module 4 comprises display unit 41; The infrared light synthetic image signal of the organism reflection that described video camera 3 receives according to described camera lens, and described picture signal is converted to data signal passes to display unit 41, display unit 41 is for showing data signal in the form of images.
The first filter plate 2 is provided with between camera lens and the first infraluminescence source 1; The infrared light that described first filter plate 2 reflects for filtering biological body also ensures that the infrared light that transmission enters camera lens filters through the first filter plate 2; Described first filter plate 2 is coaxial with camera lens, and the angle between described first filter plate 2 and the main shaft of camera lens is 45 degree.First filter plate 2 adopts infrared optics filtering technique filter plate, eliminates the impact of other veiling glares on vein image.
Display unit 41 is display screen.The auxiliary display of visual initial vein distributed image is provided.
Image-forming module 4 also comprises image processor 42 and projector 43, described image processor 42 generates monochromatic image signal according to the data signal obtained from video camera 3, and the monochromatic image signal obtained from image processor 42 is converted to monochrome image and is projected on organism by described projector 43.
The data signal that image processor 42 adopts vein enhancing algorithm process to obtain from video camera 3.After-treatment is carried out to image, makes projector 43 only throw in vein image, other skin images are directly shielded.Make vein image more clear.
Image-forming module 4 also comprises the second filter plate 5, and described second filter plate 5 is coaxial with projector 43 optical lens, and described second filter plate 5 is coaxially parallel with the first filter plate 2; Described second filter plate 5 reflexes to the first filter plate 2 for the image light sent by projector 43.
First filter plate 2 is also for reflexing to organism by reflecting the image light come from the second filter plate 5.Ensure image acquisition and image projection same light path, thus realize the position recovering of vein on skin.
Also be provided with loophole 8 below described camera lens, the infrared light of described organism reflection enters camera lens by loophole 8.
