Abstract

In recent years, the 3D scanning technology has been developed and applied in many fields such as: fashion, health, beauty, However, the 3D scanning on the human skin still has disadvantage due to the skin color and camera gain. This paper shows the result in studying the effect of hand skin color and light intensity on the accuracy of 3D scanning method using structured light. Point cloudis evaluated by the number of 3D points acquired when measured the skin surface. The result shows that the light intensity has great effect of the number of points, the same intensity on different skin colors have different numbers of points. Each color of skin corresponds to a suitable range of hightlight of camera, the light intensity of camera is from gain 4 – gain 20. The study result shows that the light intensity on bright skin should be 6 – 12, dark or brown skin should be 14 – 20, average skin color should be 9 – 15 for the best result. The studying on suitable lighting mode with each skin color is very important for the accuracy of 3D measuring method to support the beauty processes or glove designing better.
