为了满足双目立体视觉以及多通道视频成像等应用场合对微型化的需求, 提出了一种双CMOS成像器同步影像传感系统的设计方法。系统同步获取两个通道的CMOS图像并通过一路视频接口以相同帧率输出影像。系统以CPLD为核心器件, 采用乒乓操作实现了对双通道视频数据的存储与传输, 并对相应通道的图像以奇数帧和偶数帧的方式输出。CMOS成像器的配置以及数据传输采用模块化的结构设计, 使系统的稳定性和灵活性大大提高。实验表明, 系统具有良好的显示效果。

In order to meet the requirement of miniaturization in applications of binocular stereo vision and multiple-channel video imaging, a design method of dual-CMOS sensor image synchronization sensing system is proposed. The system acquires the images from two channels of CMOS synchronously, and then outputs images through a video interface. The system is designed based on CPLD, which realizes the transmission and storage of the two-channel video data by outputting in the odd frame and the even frame sequentially staggered manner. The application of the modular structure design in configuration of the CMOS sensors and data transmission, highly improves the stability and the flexibility of the system. Experiments verify good effect of display of the new system.
