      I2c脚本和v4l2接口，本质上都是通过i2c配置了camera的寄存器。所以只需要v4l做了，就无需使用脚本配置。
      是的，降低roi中的图像高度，会提升MAXFPS，你可以通过脚本获取当前配置下的max fps，然后配置fps到范围内的值。

        我现在又遇到一个问题,如果我把相机曝光设置为10000(2432*2048), 查询GET_FPS,帧率大约为38.84,那么帧周期为27902, 在此基础上用硬触发(周期为28000的脉冲,其中高电平维持10000,站空比为5:7)去拍, 比如发送10个脉冲, 那么只能收到5图,如果把触发周期改成34000以上, 那么10图都能接受到.

        我现在需要保证相机尽量快速取图,哪边还需要再配置才能获地高速?

          @hmj 按照https://wiki.veye.cc/index.php/Mv_mipi_camera_manual/zh part2.4.3的描述，你的诉求应该是没有问题的。
          你先参考这个链接，升级一下固件：https://wiki.veye.cc/index.php/Mvcam_firmware_update_manual
          然后再做一下测试试试。

            ./mv_mipi_i2c.sh -r -f version
            version is C 01.34 and L 02.00
            貌似已经是最新固件,与网站上6月5日是同一版, 无需再升级

              参考这个页面，把trigger相关的参数读出来一下，发给我看看。
              trgnum

                  @hmj 你现在读取一下fps和maxfps，分别是多少？

                      这是问题所在了。
                      虽然是触发模式，但是实际生效的帧率还是fps这个参数，maxfps永远只是最大能力的一个提示而已。
                      那么你之前

                      @hmj said in jetson nano 2GB无法识别相机 MV-MIPI-IMX264M:

                      查询GET_FPS,帧率大约为38.84,那么帧周期为27902,

                      这个地方的帧周期计算，应该使用fps来算。 这个fps不仅影响着camera真正的运作时序，也影响着最大可设的曝光时间。
                      建议你：

                      ./mv_mipi_i2c.sh -w -f fps -p1 40 -b [bus]
./mv_mipi_i2c.sh -r -f fps -b [bus]

                      这样，就把相机设置到了当前roi下最大帧率。
                      应该就没问题了。

                            我们现在基本测试已经通过,现在有个棘手的问题,由于jetson nano的mipi驱动在kernel image中,我目前的做法是直接替换官方的.

                            我们目前项目中添加了许多其他功能, 因此修改了内核的许多地方.所以为了替换之前的老相机,必须拿到你们kenrel源码和DTS, 再整合进我们目前的内核中,才能无缝完成项目的迁移.

                                相机有没有调节对比度的api, 我们目前发现图片在拍黑白图案(相机标定)时候,图片质量没有国外相机明显.

                                  @hmj 您可以通过调节gamma，或者自定义lut曲线达到这种高对比度效果。

                                    gamma设置不需要对相机做关闭操作吧,只要在不拍照的时刻进行配置即可?
                                    lut的文件,请问这个文件怎么 修改

                                      gamma随时可配。
                                      lut适用于比较专业的客户特殊要求场景下，你可以先试试gamma。

                                        我们买的一款相机现在不出图了,排除了其他原因,应该和相机相关. 从dmesg中可以看到如下log

                                        这是啥问题?

                                          这个提示是没有关系的。不影响。
                                          你查看一下配置，是否配置为触发模式了？
                                          可以尝试恢复一下出厂默认值试试，factoryparam

                                            问题是程序没改动过, 以前二个月里都没动过,也能跑出图,就昨天开始就不行了
                                            触发模式一直是外触发, 外触发信号也是合乎要求.
                                            相机设置应该也是断电不保存的.

                                            出厂值后,出现如下错误
