摘要
随着CCD相机几何分辨率和辐射分辨率的提高,其数据传输速率越来越高,传输通道也越来越多,因此对相机与采集卡之间(或者数传设备)的接口性能提出了更高的要求。文章基于并/串(串/并)转换功能的芯片,研究探讨了一种高速数字图像传输方法,可提高数据传输率,减少电缆数量,提高可靠性,为实现航天相机的轻型化、小型化作出一定的贡献。
With the improvement of geometric and radiant resolution of CCD camera, data must be transferred with higher rate and more channels, and interface between CCD camera and frame grabber with better performance was required. In this paper, a high speed digital image transmission method based on P/S or S/P conversion chip was proposed. The proposed method could increase the data transmission rate and decrease the amount of the cable, which would make the camera smaller and lighter.
