一种虚拟现实系统的手部动作捕捉方法
摘要：
本发明公开了一种虚拟现实系统的手部动作捕捉方法，涉及虚拟现实解析技术领域，具体捕捉过程包括以下步骤，步骤1：初始化；步骤2：摄像头开启后，当检测到可靠人脸时，建立肤色高斯模型；步骤3：当在视频流中检测到start＝1且gesture＝-1时转步骤4；步骤4：用当前帧与步骤1中设定的背景图bgimg做差分的到差分二值图chafenimg，判断此帧为手势稳定帧，令gesture＝1转步骤5；步骤5：得到手部动作二值图。本发明的虚拟现实系统的手部动作捕捉方法，大大提高动作捕捉的正确率及速度，满足实时捕捉的要求。
摘要（英）：

The invention discloses a hand action capturing method for a virtual reality system, and relates to the technical field of virtual reality analysis. The specific capturing process comprises the following steps: step 1, initializing; step 2, after a camera is started, when a reliable face is detected, establishing a skin color Gaussian model; step 3, when start=1 and gesture=-1 are detected in video stream, turning to step 4; step 4, performing differentiation on the current frame and a background image bgimg set in step 1 to obtain a differential binary image chafenimg, judging that the frame is a gesture stable frame, supposing gesture=1 and turning to step 5; and step 5, obtaining a hand action binary image. The hand action capturing method for the virtual reality system greatly improves the action capturing accuracy and speed, and meets the real-time capturing requirement.
