信息叠加 meaning in English
information overlays
Examples
- Within a communication system the information transfer is frequently achieved by superimposing or modulating the information on to an electromagnetic wave which acts as a carrier for the information signal
在通信系统中,信息传递通常是通过把信息叠加,调制,加到一个充当信息信号传输载体的电磁波上来完成的 - Augmented reality systems add virtual computer - generated material to the surrounding physical world to improve the person ' s perception . as the person moves about , the position and orientation of his or her head is tracked , allowing the overlaid material , such as graphic , image , sound and so on , which is generated from the computer , to remain tied to the physical world
增强现实系统通过跟踪用户在现实场景中所处的位置,将计算机生成的图形图像以及声音等虚拟信息叠加在用户感知的真实世界之中,利用辅助的虚拟信息增强用户对真实场景的感知能力。 - During the realization of the prototype , it collects the video of real scenes firstly , identifies the markers in the video images to obtain the information of them , calibrates the camera parameter based on the markers ’ information , registers the virtual scenes and real world to obtain the relationship matrix of them , and finally realizes the blending of the virtual scenes and the real scenes
在系统实现过程中,系统首先采集现实场景视频,通过对视频图像中的marker进行识别,获取marker的相关参数,在获取这些信息的基础上定标摄像机的参数,对虚拟信息与真实世界进行配准,确定屏幕坐标与世界坐标的变换关系,最后将虚拟信息叠加到真实场景视频图像中,从而实现虚拟信息与现实场景的融合。
