1. Install opencv:

2. Then import cv2 reports an error: Illegal instruction (core dumped)

3. Solution:
sudo vi ~/.bashrc
Add
export OPENBLAS_CORETYPE=ARMV8 at the end
and run:
source ~/.bashrc
to solve the error.
4. Create a new camer.py file:

import cv2
cap = cv2.VideoCapture(0)
while True:
    ret, frame = cap.read()
    frame = cv2.flip(
            frame,
            1  # 1：水平镜像，-1：垂直镜像
        )
    cv2.imshow('frame', frame)
    # 这一步必须有，否则图像无法显示
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
# 当一切完成时，释放捕获
cap.release()
cv2.destroyAllWindows()

5. Enable xfce4:

root@myir:~# startxfce4
6. Execute camer.py with python3

【Summary】It took a little time to install opencv to drive the USB camera. opnecv can help the development board to complete many things.
