Vein Visualization System Using Camera and Projector Based on Distance Sensor

The location of the veins of every person is different, some are visible with the naked eye and some are invisible. This is due to the location of the veins deep below the skin, usually due to excessive fat covered. Many papers that have the topic to solve this difficulty mostly perform only image processing without back-projection. In this paper, we propose a method for improving vein image enhancement using high boost filter and preliminary study about back projection by using the intersection between camera view and projector view. Vein data acquired by NIR reflection method. The obtained vein image enhanced by using a high-boost filter. To deal with the post-segmentation noise, we use a combination of morphology and contour area. Based on these combinations, the accuracy of vein detection is 84.62%. The result of the preliminary study about back-projection is already able to project the vein image and the future work is focused on adjusting the projection in term of distance change between device and object.
