Python读取realsense彩色图像并且抽帧保存图片(数据集制作)

import cv2
import pyrealsense2 as rs
import numpy as np

pipeline = rs.pipeline()   # 构建一个抽象设备的管道
config = rs.config()  # 使用非默认配置文件创建配置以配置管道
config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)
profile = pipeline.start(config)  # 表示构建的管道使用上述配置开始流传输
# frames = pipeline.wait_for_frames()  # 等待所有配置的流生成一个帧
# color_frame = frames.get_color_frame()  # 从帧集合中调取彩色帧
# color_image = np.asanyarray(color_frame.get_data())  # 从彩色帧中取图像
camera = cv2.VideoCapture(0)
flag = camera.isOpened()
index = 0
imgname = 0
while (True):
    index += 1  # 500ms加一次
    reg, img = camera.read()
    cv2.imshow('Camera', img)

    if index == 2:
        imgname += 1
        fname = str(imgname) + '.jpg'
        cv2.imwrite('C:/Users/yons/Desktop/2020.9.11/img' + fname, img)    # 路径换成自己的路径
        print("saved sucessful")
        index = 0
