Description

Within the WSL environment accessing the Mendel environment on the Coral dev board, when using code python3 test.py access the camera, Code 1 encounters an error and cannot run successfully. Code 2 runs, and the camera indicator lights up, but the video information window does not display.

code1:
`import cv2

capture = cv2.VideoCapture(1)
while capture.isOpened():
retval, image = capture.read()
cv2.imshow("Video", image)
key = cv2.waitKey(1)
if key == 32:
break

capture.release()
cv2.destroyAllWindows()`

error:
`qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/mendel/.local/lib/python3.7/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted`

code2:
`import cv2
import matplotlib.pyplot as plt

capture = cv2.VideoCapture(1)

while capture.isOpened():
retval, image = capture.read()

if retval:
    # 使用 Matplotlib 显示图像
    plt.imshow(cv2.cvtColor(image, cv2.COLOR_BGR2RGB))
    plt.show()

key = cv2.waitKey(1)

if key == 32:
    break

capture.release()
cv2.destroyAllWindows()`
