Jetson Nano 使用Opencv抓图

Sensor型号：树莓派 IMX219

在Opencv中读取并保存图像数据，

图像读取 cap = cv2.VideoCapture()，参数需要注意。

import cv2

import numpy as np

impor tpickle

import matplotlib.pyplot as plt

cap = cv2.VideoCapture("nvarguscamerasrc ! video/x-raw(memory:NVMM),

width=(int)1280, height=(int)720,format=(string)I420,

framerate=(fraction)30/1 ! nvvidconv flip-method=0 ! video/x-raw,

format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR !

appsink")

frame =cap.read()

cv2.imshow('frame',frame )

cv2.imwrite("kk.jpg",frame)
