三、打开板载摄像头

def open_cam_onboard(width, height):gst_elements = str(subprocess.check_output('gst-inspect-1.0'))if 'nvcamerasrc' in gst_elements:# On versions of L4T prior to 28.1, add 'flip-method=2' into gst_strgst_str = ('nvcamerasrc ! ''video/x-raw(memory:NVMM), ''width=(int)2592, height=(int)1458, ''format=(string)I420, framerate=(fraction)30/1 ! ''nvvidconv ! ''video/x-raw, width=(int){}, height=(int){}, ''format=(string)BGRx ! ''videoconvert ! appsink').format(width, height)elif 'nvarguscamerasrc' in gst_elements:gst_str = ('nvarguscamerasrc ! ''video/x-raw(memory:NVMM), ''width=(int)1920, height=(int)1080, ''format=(string)NV12, framerate=(fraction)30/1 ! ''nvvidconv flip-method=2 ! ''video/x-raw, width=(int){}, height=(int){}, ''format=(string)BGRx ! ''videoconvert ! appsink').format(width, height)else:raise RuntimeError('onboard camera source not found!')return cv2.VideoCapture(gst_str, cv2.CAP_GSTREAMER)

参数解释：
gst_str = ('nvarguscamerasrc ! ''video/x-raw(memory:NVMM), ''width=(int)1920, height=(int)1080, ''format=(string)NV12, framerate=(fraction)30/1 ! ''nvvidconv flip-method=2 ! ''video/x-raw, width=(int){}, height=(int){}, ''format=(string)BGRx ! ''videoconvert ! appsink').format(960, 640)
return cv2.VideoCapture(gst_str, cv2.CAP_GSTREAMER)视频流：1920*1080 @30fps
显示窗口：960*640
