      @maifengw2023 你用的驱动是从源码编译的吗?用哪个目录下的编译的?

        @veye_xumm 直接下载的,我又做了系统,最新的5.15.84;
        wget https://github.com/veyeimaging/raspberrypi_v4l2/releases/latest/download/raspberrypi_v4l2.tgz

              @veye_xumm 需要重新安装驱动程序吗?链接地址方便发一下吗?
              另外能不能给个例程,修改曝光时间、修改增益及修改是否硬件触发的例程,非常感谢!

                按照wiki上脚本直接配置就可以。

                      这个目录下的我手头的板子不是此版本,你需要在你的板子上编译一下,然后拷贝到此目录,再次安装。

                        郁闷死了,编译总是报错,没有内核下的build文件夹,又要下载更新,安装内核,原来系统就是因为问题,升级了系统,这样搞太不方便了,这个驱动形式兼容性需要解决一些,要不然不同的版本都需要编译驱动,这样有点不合适!
                        内核升级了,还是没有这个文件夹,哎!

                          你们能帮忙编译一下吗?折腾这个内核,我都搞了两天了,昨天晚上搞到半夜,这个对系统级的操作还是有点不足,这样折腾真的受不了!

                            2. 从这个链接中查找到对应当前的版本的deb安装包并安装。
                            tag请根据本机piOS版本与raspberrypi OS tags确定。

                            这个更新内核,我是不是应该下这个;

                                对于从32位系统升级的树莓派4,现在默认会给切换到64位,但是编译环境不全。
                                可以在/boot/config.txt中添加arm_64bit=0然后重启,切换回32bit模式。
                                我已编译好了6.1.21-v7l+版本,请留一个邮箱。收到后:

                                1. 在/boot/config.txt中添加arm_64bit=0然后重启,切换回32bit模式。
                                2. 按照正常步骤安装veye_mvcam驱动即可。

                                        在树莓派4B上,v4l2模式可以调用流模式的图像;但是在3088X2064模式下,VLC跟QT调取的图像都是两半;
                                        413c9fcd-b756-45a5-b616-8c1aa6c4e961-image.png
                                        请问IMX178M都支持多少的分辨率?
                                        流模式下,我可以用线程不停的刷图像,但是在外触发模式下,我在什么时机接收图像?像海康的提供的有摄像头的回调函数
                                        MyCamera->RegisterImageCallBack(ImageCallBack, this),
                                        咱们的有没有类似的功能?
                                        在178的wiki文档中还是没有找到设置曝光时间跟增益设置的指令,请帮忙提供链接;程序开发采用的是opencv+v4l2.

                                            相机支持灵活的roi配置,通过脚本或者v4l2-ctl可以配置的。

                                            使用v4l2接口持续获取即可,如果有触发,则底层就会图返回上来。

                                            从6.6往后看即可。

                                            感觉你现在这个应该是摄像机分辨率和你显示的地方以为的分辨率不一致。最好通过脚本读取一下roi,跟你的程序对比一下。
