        您好 多个摄像头拍照的同步性是不是跟我写得代码有关

            @lll 多个相机采用同一个触发信号的话,硬件层面上就保证了【拍摄】时刻的同步性。至于你的软件获取数据,只要正确获取,且没有过大的延时,不会影响同步性。

              @veye_xumm我使用了python的多进程通过opencv来抓图 对于运动目标的话 有时候会出现不对齐的情况

                  请问你这个情况是错帧吗?比如camera1的第N帧和camera2的第N+1帧不对齐?

                  Jetson系统应该是提供了接收到一帧数据的时候的时间戳的,你可以到英伟达的资料库找一下,能不能把这个时间戳用起来。

                    @veye_xumm 我只是简单的做了一个对秒表拍摄的试验,就是作用相机拍到的时间有时候会有点偏差,特别是相机轻微晃动的时候

                      @lll 偏差是多少? 曝光时间配置的是多少?

                        @veye_xumm 抓拍的一组图是0.07 曝光时间的话是原始设置的 不太清楚

                          @lll 做这种测试,你最好用手动曝光,把曝光时间拉低。原理上,传感器出的图肯定是同步的。 可能是后面到主板之后预览的时候,每个进程缓存的buffer数量有不同,有波动。

                            @veye_xumm 曝光时间是只能通过那个脚本文件进行修改么

                              @lll 是的。本质上是修改对应的寄存器即可。
