          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

                  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

                      [ 33.578643] mvcam 7-003b: camera_common_mclk_enable: no device power rail
                      [ 34.087223] mvcam 7-003b: camera_common_mclk_disable: no device power rail
                      [ 34.094119] mvcam 8-003b: camera_common_mclk_enable: no device power rail
                      [ 34.602642] mvcam 8-003b: camera_common_mclk_disable: no device power rail
                      [ 34.609562] mvcam 7-003b: camera_common_mclk_enable: no device power rail

                      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

                            看起来这个没有错误。 不过你的程序好像给配置成了触发模式。
                            相机的参数是可以保存的，只要你通过脚本调用一下paramsave。
                            我的建议是你把摄像头恢复默认值——这样也就恢复为了图像流模式。
                            不要运行你的现在的程序——配置为触发啊之类的。
                            然后用qv4l2程序来取图看看。
