| 内容記述 | With the development of Augmented Reality (AR) technology in recent years, it has become possible for user to manipulate objects in virtual space as if they were operating objects in real space. In addition, it has been attracted on interaction technologies that allow users to manipulate virtual objects directly with their bare hands, aiming for more intuitive manipulation similar to real space. Therefore, we believe that a more accurate overlay technique between real and virtual space is required for a more seamless interaction. On the other hand, in augmented reality, a three-dimensional (3D) model is superimposed later on the image in real space, so that it is always displayed in front of the hand. Thus, in some cases, it becomes an unnatural scene (occlusion problem). Interaction manipulations in augmented reality will be increasingly required in the future, and more precise manipulations will be required. Therefore, we seek to consider hidden surface removal along the user's fingertips. In this study, the depth relationship between the user's hand and the virtual object is considered by acquiring depth information of the user's finger using a depth sensor. In addition, we propose a method to extract the area of the hand in real time by analyzing the state of the color distribution near the acquired finger position. Also, when performing an operation of grasping a virtual object, the thumb and other fingers could not be distinguished, and hidden surface processing was sometimes performed inappropriately. Therefore, in this study, we propose a method that uses the Canny method to distinguish between the thumb and other fingers and perform appropriate hidden surface processing. In this way, this system realizes the removal of hidden surfaces along the area of the user's hand. In the evaluation experiment, by using the hidden surface removal of this study, the boundaries of the fingers are distinguished and the outline of the fingers is clarified. Confirmed that it can be processed. | |||||
