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 demand for miniaturization for binocular stereo vision and multi-channel video imaging applications, a method for designing a dual CMOS imager synchronous image sensing system is proposed. The system simultaneously acquires two channels of CMOS images and outputs the images at the same frame rate through one video interface. The system regards CPLD as the core device, adopts the ping-pong operation to realize the storage and transmission of the dual-channel video data, and outputs the images of the corresponding channels in odd-numbered frames and even-numbered frames. CMOS imager configuration and data transmission using modular structure design, the stability and flexibility of the system greatly improved. Experiments show that the system has a good display.
