实现色彩分割基本步骤

其原理同静态图像色彩分割一致：OpenCV + Python 实现静态图像色彩分割

---

Code：

#--coding: utf-8--
import cv2 as cv
import numpy as np


def color_seperate():
        capture = cv.VideoCapture('/home/pi/Desktop/绿裤子.mp4')   #导入视频
        while True:
                ret, frame = capture.read()   #获取每一帧图像信息
                hsv = cv.cvtColor(frame, cv.COLOR_BGR2HSV)   #将BGR 转化为HSV 
                lower_hsv = np.array([25, 30, 30])   #设定目标颜色上下限
                upper_hsv = np.array([77, 255, 46])
                mask = cv.inRange(hsv, lowerb=lower_hsv, upperb=upper_hsv)   #开始分割绿色
                dst = cv.bitwise_and(frame, frame, mask=mask)   #实际是提取前两个frame 的“与”结果，然后输出mask 为1的部分
                cv.imshow('video', frame)
                cv.imshow('result', dst)
                c = cv.waitKey(40)
                if cv.waitKey(50) & 0xFF == ord('q'):
                        break


color_seperate()
cv.waitKey(0)
cv.destoryAllWindows()

结果：
