            @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:
                        ret,frame=cap.read()
                        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:

                                  import cv2 as cv2
                                  cap = cv2.VideoCapture(11)
                                  while True:
                                      success, img = cap.read()
                                      cv2.imshow("Video", img)
                                      if cv2.waitKey(1) & 0xFF == ord('q'):
                                          break
                                  cap.release()
                                  cv2.destroyAllWindows()

                                        @wuming dmesg打印一份传上来,这种情况是没有识别到摄像头模组。
