        @veye_xumm 就是把demo里最后循环里的cv2.imshow改成了计数。因为显示图片没法判断帧数。所以我改成了1s的计数。最后只有20截屏2024-01-19 17.58.13.png 截屏2024-01-19 17.58.33.png
        把上面demo里的代码改成了下面的计数

          @lizi 如此说来确实有这个问题。我们主要提供好驱动,opencv不是很熟。
          你用jetson平台,最好还是用带jetson的硬件加速的开发包去开发。比如CUDA之类。
          我们应用层和算法都不太熟悉。你可以到英伟达的开发者网站上找找资料。

            @veye_xumm 那有没有办法用v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT,pixelformat=GREY --stream-mmap --stream-count=-1 --stream-to=/dev/null这个捕获帧的方法去捕获图片啊,这个获取的图片是raw格式的吗?

              我测了一下orin nano上面,实际采集数据的帧率是没有问题的。 你可以延长你的代码的统计时间到10秒,100秒,可以发现帧率会趋近于接近60fps。

              那么为何出现你只统计1秒的时候,帧率只有20帧的结果呢? 我进行了一下简单的时间分析,发现是第一次调用cap.read()函数的时候,耗时大约半秒左右。(估计是底层进行buffer的初始化之类的操作。)

              可以参考我贴上来这个代码:

              import cv2
              import argparse
              import subprocess
              import time
              
              def main():
                  # Set up command-line argument parser
                  parser = argparse.ArgumentParser(description='Real-time display of GREY image from /dev/video0')
                  parser.add_argument('--roix', type=int, default=0, help='roi start x (default: 0)')
                  parser.add_argument('--roiy', type=int, default=0, help='roi start y (default: 0)')
                  parser.add_argument('--width', type=int, default=1920, help='image width (default: 640)')
                  parser.add_argument('--height', type=int, default=1200, help='image height (default: 480)')
                  parser.add_argument('--fps', type=int, default=60, help='frame rate (default: 30)')
                  args = parser.parse_args()
                  
                  v4l2_cmd = f"v4l2-ctl --set-ctrl roi_x={args.roix}"
                  subprocess.run(v4l2_cmd, shell=True)
                  
                  v4l2_cmd = f"v4l2-ctl --set-ctrl roi_y={args.roiy}"
                  subprocess.run(v4l2_cmd, shell=True)
                  
                  v4l2_cmd = f"v4l2-ctl --set-fmt-video=width={args.width},height={args.height}"
                  subprocess.run(v4l2_cmd, shell=True)
                  
                  v4l2_cmd = f"v4l2-ctl --set-ctrl frame_rate={args.fps}"
                  subprocess.run(v4l2_cmd, shell=True)
                  
                  # Open the /dev/video0 device
                  cap = cv2.VideoCapture('/dev/video0')
                  if not cap.isOpened():
                      print("Failed to open video device")
                      return
              
                  # Set the image size
                  cap.set(cv2.CAP_PROP_FRAME_WIDTH, args.width)
                  cap.set(cv2.CAP_PROP_FRAME_HEIGHT, args.height)
              
                  frame_num = 0

                  while True:
                      # Read a frame
                      ret, frame = cap.read()
                      # Check if reading was successful
                      if ret:
                          if frame_num == 0:
                              time_start = time.perf_counter()
                          frame_num += 1

                          @lizi i2c不通,你查查硬件连接,比如fpc排线方向。

                            这是两边的插线方向。这个是对的吗orin-nano的有数据的线朝外侧,mipi有数据的线朝下方

                              @veye_xumm 还是有这个问题,这个是说明驱动式成功安装了是吗?只是硬件上的传输有问题吗

                                  @veye_xumm 目前是没改dts的。就是默认的dts。之前在树莓派上安装了驱动测试是没问题的。
