【CV】OpenCV中HSV各颜色的区间及代码
按照上表的OpenCV（Python）代码↓↓↓
# 定义HSV颜色范围
# 红
minRed1 = np.array([0, 43, 46])
maxRed1 = np.array([10, 255, 255])
minRed2 = np.array([156, 43, 46])
maxRed2 = np.array([180, 255, 255])
# 橙
minOrange = np.array([11, 43, 46])
maxOrange = np.array([25, 255, 255])
# 黄
minYellow = np.array([26, 43, 46])
maxYellow = np.array([34, 255, 255])
# 绿
minGreen = np.array([35, 43, 46])
maxGreen = np.array([77, 255, 255])
# 青
minCyan = np.array([78, 43, 46])
maxCyan = np.array([99, 255, 255])
# 蓝
minBlue = np.array([100, 43, 46])
maxBlue = np.array([124, 255, 255])
# 紫
minPurple = np.array([125, 43, 46])
maxPurple = np.array([155, 255, 255])
# 黑
minBlack = np.array([0, 0, 0])
maxBlack = np.array([180, 255, 46])
# 灰
minGray = np.array([0, 0, 46])
maxGray = np.array([180, 43, 220])
# 白
minWhite = np.array([0, 0, 221])
maxWhite = np.array([180, 30, 255])
# 得出二值化后的图片
ans1 = cv.inRange(imgHSV, minRed, maxRed)
ans2 = cv.inRange(imgHSV, minGreen, maxGreen)
ans3 = cv.inRange(imgHSV, minYellow, maxYellow)
