python - 从python将颜色值拉入firebase

Question

该程序用于检测红色和绿色的值并自动将它们输入到 firebase。但是我试图让程序只自动将绿色值输入到firebase而不是红色和绿色。例如。我希望 firebase 只显示检测绿色而不是红色和绿色的数据。

data=[("color1":"green")

有谁知道我应该怎么做？这是我的代码。谢谢你。

import numpy as np
import cv2
from firebase import firebase


url=firebase.FirebaseApplication('https://tesla-2d23e-default-rtdb.firebaseio.com/')

red_lower = np.array([-10,100,100])
red_upper = np.array([10,255,255])#这里是设置颜色
green_lower = np.array([35,43,46])
green_upper = np.array([77,255,255])

**data=[("color1":"green")
url.posr("/users",data)**


cap = cv2.VideoCapture(0)

cap.set(3, 320)
cap.set(4, 240)

while 1:
    ret, frame = cap.read()
    frame = cv2.GaussianBlur(frame, (3, 3), 0)
    hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV)
    red_mask = cv2.inRange(hsv, red_lower, red_upper)
    green_mask = cv2.inRange(hsv, green_lower, green_upper)
    mask = cv2.bitwise_or(red_mask, green_mask)

    # 图像学膨胀腐蚀
    mask = cv2.erode(mask, None, iterations=2)
    mask = cv2.GaussianBlur(mask, (3, 3), 0)
    res = cv2.bitwise_and(frame, frame, mask=mask)
    # 寻找轮廓并绘制轮廓
    cnts = cv2.findContours(mask.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)[-2]

    if len(cnts) > 0:
        # 寻找面积最大的轮廓并画出其最小外接圆
        cnt = max(cnts, key=cv2.contourArea)
        (x, y), radius = cv2.minEnclosingCircle(cnt)
        cv2.circle(frame, (int(x), int(y)), int(radius), (255, 0, 255), 2)
        # 找到物体的位置坐标,获得颜色物体的位置，可以来控制小车的转向
        #print(int(x), int(y))
    else:
        pass
    cv2.imshow('frame', frame)
    cv2.imshow('mask', mask)
    cv2.imshow('res', res)

    if cv2.waitKey(5) & 0xFF == 27:
        break
cap.release()
cv2.destroyAllWindows()
