| Zusammenfassung: | The invention discloses a device for vein navigation. A skin area exposed to an infrared light source is obtained through a sensitization device, an image is transmitted to a microprocessing unit, undergoes processing of an image algorithm, such as enhancement, extraction and reconstruction, is transmitted to a projection module and is projected to an image collecting area through the projection module, and it is guaranteed that the projected image and an originally collected image coincide under the working distance conditions. A method for vein navigation is further disclosed. According to the device and method for vein navigation, doctors are assisted to operate blood vessels, the device has the advantages of being compact in structure and good in real-time performance, and the processed image can be completely projected to the surface of the skin according to the proportion of 1:1. |
