Python，如何连接/填充线条、方框或圆圈中的间隙( OpenCV )

import cv2
import numpy as np

# 读取图像
image = cv2.imread('image.jpg')

# 转换为灰度图像
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

# 二值化处理
ret, thresh = cv2.threshold(gray, 127, 255, cv2.THRESH_BINARY)

# 查找轮廓
contours, hierarchy = cv2.findContours(thresh, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

# 绘制轮廓并填充内部
cv2.drawContours(image, contours, -1, (0, 255, 0), thickness=cv2.FILLED)

# 显示结果
cv2.imshow('Filled Contours', image)
cv2.waitKey(0)
cv2.destroyAllWindows()

import cv2

# 创建一个黑色图像
image = np.zeros((400, 400, 3), dtype=np.uint8)

# 绘制方框并填充内部
cv2.rectangle(image, (50, 50), (200, 200), (0, 255, 0), thickness=cv2.FILLED)

# 绘制圆圈并填充内部
cv2.circle(image, (300, 300), 100, (0, 0, 255), thickness=cv2.FILLED)

# 显示结果
cv2.imshow('Filled Shapes', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
