matplotlib.pyplot.imshow & opencv.imread 图片显示 & 图片读取

    # opencv中图像以BGR通道顺序存储
    # Matplotlib以RGB通道顺序存储
    # 2种解决方式：
    # 1.

import cv2 as cv
raw = cv.imread('xxx')
converted = cv.cvtColor(raw,cv.COLOR_BGR2RGB)

    # 2.

converted = raw[:, :, ::-1]
# 或者
# b, g, r = cv.split(res)
# converted = cv.merge([r, g, b])
