Opencv 4.1 打开Jetson TX 2 板载摄像头

Opencv 4.1 打开Jetson TX 2 板载摄像头

网上总结很多opencv打开板载摄像头方法,但大多需要卸载刷机安装的原始opencv. 下面我的方法则不用,只需要运行python文件。

// An highlighted block
import cv2
def open_cam_onboard(width, height):
    gst_str = ('nvarguscamerasrc ! '
               'video/x-raw(memory:NVMM), '
               'width=(int)2592, height=(int)1458, '
               '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)
    return cv2.VideoCapture(gst_str, cv2.CAP_GSTREAMER)
cap=open_cam_onboard(500,300)
while(True):	
	ret,frame=cap.read()
	frame=cv2.flip(frame,-1) #翻转
	cv2.imshow('frame',frame)
	if cv2.waitKey(1) == ord('q'):
		break

运行即可
