在python中使用opencv识别图像中的颜色

import cv2
import numpy as np

image = cv2.imread('image.jpg')

hsv_image = cv2.cvtColor(image, cv2.COLOR_BGR2HSV)

lower_color = np.array([h_min, s_min, v_min])
upper_color = np.array([h_max, s_max, v_max])

mask = cv2.inRange(hsv_image, lower_color, upper_color)

kernel = np.ones((5, 5), np.uint8)
mask = cv2.morphologyEx(mask, cv2.MORPH_OPEN, kernel)

contours, _ = cv2.findContours(mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

for contour in contours:
    x, y, w, h = cv2.boundingRect(contour)
    cv2.rectangle(image, (x, y), (x + w, y + h), (0, 255, 0), 2)

cv2.imshow('Result', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
