怎么用python版本的opencv扫描aruco

要使用Python版本的OpenCV扫描ArUco，需要先安装OpenCV和ArUco模块。可以使用以下命令安装：

pip install opencv-python
pip install opencv-contrib-python
pip install numpy
pip install pillow

然后，可以使用以下代码来检测ArUco标记：

import cv2
import cv2.aruco as aruco

# Load the predefined dictionary
dictionary = aruco.getPredefinedDictionary(aruco.DICT_6X6_250)

# Initialize the detector parameters
parameters = aruco.DetectorParameters_create()

# Load the image
image = cv2.imread('path/to/image.jpg')

# Convert the image to grayscale
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

# Detect the markers in the image
corners, ids, rejectedImgPoints = aruco.detectMarkers(gray, dictionary, parameters=parameters)

# Draw the detected markers on the image
image_with_markers = aruco.drawDetectedMarkers(image, corners, ids)

# Show the image with markers
cv2.imshow('Image with markers', image_with_markers)
cv2.waitKey(0)

这个代码片段将检测图像中的ArUco标记，并在图像上绘制检测到的标记。你可以将`path/to/image.jpg`替换为你要检测的图像的路径。
