        首先你所说的外触发帧率是10,应该是你理想中的触发间隔,而不是相机的帧率。相机的帧率继续使用50fps的配置是没问题的。
        我给你解释一下rolling shutter。
        按照1920*1080分辨率,50fps的配置。我计算了一下,每行的传输周期大约是18us。
        也就是说,收到触发信号之后,第一行开始曝光,然后延迟18us第二行开始曝光,再延迟18us后第三行开始曝光。

        所以我的建议还是你选用global shutter的相机进行开发。全局曝光相机的好处是,收到触发信号之后,立刻开始全局一起曝光(不设置触发延迟的情况下),到约定的曝光时间完成之后,立刻同时结束曝光。时序上可控性更好。
