        @jugg 这种出来就是2个独立摄像头。上午做了一条排线,预计10天左右可以出来。这种就可以直接接2个树莓派标准15PIN的摄像头。

            @wuming 如果需求比较多,可以做一批出来。主要是需要贴片,数量少成本太高。

                  @george 如果这个csi口不能很好的用起来,就没有意义了

                    @wuming 这个接口意义非常大,直接驱动4个摄像头可以做360环视。再加转换芯片以后可以做到8个摄像头同时工作。后续如果有这方面需求可以提出来,我们会有针对性的出一些转接小板。

                                使用一下代码,不能够打开mx219摄像头:a8411b3b-ccc6-4e99-9d5a-6619550a3ed7-c73827008f721de0edfd9b292ff34b1.jpg
                                import cv2
                                cap=cv2.VideoCapture(0)
                                while True:

                                cv2.imshow('frame',frame)
                                if cv2.waitKey(1)&0xFF==ord('q'):
                                break
                                cap.release()
                                cv2.destroyAllWindows()

                                  @wuming 内核同步到最新,确认系统可以生成video11节点。mipi摄像头默认的设备节点是video11
                                  然后运行如下命令更新ISP库:

                                  sudo apt-get update
                                  sudo apt-get dist-upgrade

                                        @wuming 先使用QV4L2打开video11节点,系统默认已经安装。

                                          @george 如下代码测试正常:

                                          cap = cv2.VideoCapture(11)

                                              success, img = cap.read()
                                              cv2.imshow("Video", img)
                                              if cv2.waitKey(1) & 0xFF == ord('q'):
                                                  break
                                          cap.release()
                                          cv2.destroyAllWindows()
