APPARATUS FOR TOUCHING A PROJECTION OF 3D IMAGES ON AN INFRARED SCREEN USING MULTI-INFRARED CAMERA |
| 摘要 |
<p>PURPOSE: A projection image touch apparatus of a multi infrared ray camera for utilizing z-axis of an infrared screen as depth information is provided to implement various user interfaces by utilizing a z-axis as depth information. CONSTITUTION: An infrared ray emitting diode array(140) emits infrared ray and generates an infrared screen in the space. A projector projects an image on an infrared ray screen. A left and right infrared camera is installed in the left and right side of the support stand. A spatial touch recognition module(190) calculates X, Y, Z-axis of an infrared screen by using view angle and resolution of the infrared camera.</p> |
