中文摘要：

文章选用电荷耦合元件（Charge—coupled device，CCD）摄像头传感器，采用ARToolKit开发包设计并实现一个虚拟手表试戴系统。通过CCD摄像头采集真实场景中的视频图像，使用ARTooKit对CCD摄像头采集的图像进行分析、识别，并动态跟踪位于用户手腕上的标识，使虚拟手表模型可以准确地叠加在标识处，从而实现虚拟手表试戴。

英文摘要：

On the research of virtual try-on based on computer vision and augmented reality, the high cost of traditional display and sale model is reduced and the customer＇s online shopping experience is enriched. The paper implemented a virtual watch try-on system based on ARToolKit. The principle and the design of the con- struction are explained including the detection and registration of the marker, the combination of real video and virtual watch with real time tracking. The performance and experimental results show the higher recognition of the marker, the natural experience provided to users and the satisfaction of the application. The research of vir- tual try-on provides some guidance for other precious commodities.
