| Abstract: | Objective： To improve the front-end image acquisition quality to make vein image clearer. Methods： Through analysis the imaging theory, adjustment the power of LED light source, select appropriate filters, design the interface circuit to get the best image in the fore- end system. Results： Improve every phase of the image acquisition would make the image more clearly. Conclusion： The high image quality got in the fore-end will useful in the chose about image processing, so the fore-end design of vein imaging system is necessary for the whole system. |
