我討厭綠色

Concept Development

網路上常看到說今天星座幸運顏色是什麼，但因為每一次都要上網去查很麻煩，所以我們就決定要做一個可以幫你查幸運色同時也強迫你要穿幸運色的衣服

Webcam

先更新軟體套件
```
sudo apt update
sudo apt upgrade
```
確認 webcam 裝置
```
sudo lsusb
```
安裝 numpy 套件
```
pip install numpy
```
安裝 opencv
```
sudo apt-get install libopencv-dev
```
安裝 imutils
```
pip install imutils
```

程式碼 - ReadWebcam.py 感測 rgb 數值

# importing required libraries
import cv2
import numpy as np
import matplotlib.pyplot as plt

from imutils.video import VideoStream
from xlsxwriter import Workbook

class color:
    def run(self):
# taking the input from webcam

    plt.ion()  # Set interactive mode on

    # We will be using Video-capture to get the fps value.
    capture = cv2.VideoCapture(0)

    capture.release()

    # New module: VideoStream
    vs = VideoStream().start()

    timers = 5

    while timers>0:
        frame = vs.read()

        if frame is None:
            print("Frame is not found!")
            break

        b, g, r = cv2.split(frame)

        b_mean = np.mean(b)
        g_mean = np.mean(g)
        r_mean = np.mean(r)


        print("r:"+str(r_mean)+", g:"+str(g_mean) + ", b:" + str(b_mean))
        timers -= 1
        return list([r_mean,g_mean,b_mean])

if __name__ =='__main__':
        mydev=color()
        print(mydev.run())

程式碼 - detectcolor.py 根據 rgb 分析其對應到的顏色

class detector:
def __init__(self,r,g,b):
    count =0
    array = []
    self.r=int(r)
    self.g=int(g)
    self.b=int(b)

def test(self):
    mx = max(self.r,self.g,self.b)
    mn = min(self.r,self.g,self.b)
    df = mx - mn
    if mx == mn:
        h = 0
    elif mx == self.r:
        h = (60 * ((self.g-self.b)/df)+ 360) % 360
    elif mx ==self.g:
        h = (60 * ((self.b-self.r)/df)+ 120) % 360
    elif mx ==self.b:
        h = (60 * ((self.r-self.g)/df)+ 240) % 360
    if mx == 0:
        s =0
    else:
        s = df/mx

    v = mx

    if v >= 0.5 and v<=0:
        return "黑"

    else:
        if s<=0.43:
            if v > 0.5:
                return "白"
            else:
                return "灰"
        else:
            if h>0 and h<30 or h>=330 and h<=360:
                return "紅"
            elif h>=30 and h<90:

創建 telegrambot

1.找到 BotFather 輸入 /newbot

2.填完所資料(注意:username 要使用 OObot 結尾)

3.拿出 token 並放入新建的檔案 LSA1101_bot_api.txt

4.輸入/mybot 並選擇剛剛設定的 telbot

5.在 Edite bot 中的 Edite command 輸入 botcommand 檔案中的命令，以此宣告命令

telegram_bot.py

1.引入 telegrambot python 套件

    from telegram.ext import Updater # 更新者
    from telegram.ext import CommandHandler, CallbackQueryHandler # 註冊處理 一般用 回答用
    from telegram.ext import MessageHandler, Filters # Filters過濾訊息
    from telegram import InlineKeyboardMarkup, InlineKeyboardButton # 互動式按鈕

2.初始化 bot

self.updater = Updater(token=self.token, use_context=False) #放入token
self.dispatcher = self.updater.dispatcher  #用來抓使用者丟給bot的命令
self.dispatcher.add_handler(CommandHandler('/命令名稱', 命令的function))

3.讓 telegrambot 運作

mybot.updater.start_polling()  #updater.start_polling()會讓他一直持續處理你定義的handeler直到關閉

crawler.py

1.sudo apt-get install chromium-chromedriver #安裝 chromedriver

2.將安裝好的路徑放入 drivePath.txt(請自己新建)

3.設定 driver

with open("drivePath.txt", "r") as f:
    self.drivePath = f.read().strip()
options = webdriver.ChromeOptions()
options.add_argument("-headless")  #沒有圖形介面的裝置一定要加這個
self.browser = webdriver.Chrome(executable_path=self.drivePath,
                                options=options)

4.抓取資料

def get_html(self,starsign):
    if starsign=='白羊座':
        starsign='牡羊座'
    from urllib.request import urlopen
    url = "https://www.elle.com/tw/starsigns/today/"
    html = urlopen(url)
    bsObj = BeautifulSoup(html.read(), "html.parser")
    All_starsigns = bsObj.findAll("a", {"class": "custom-item-title item-title"})
# All_starsigns= self.browser.find_element_by_link_text(starsign)
    for i in All_starsigns:
        #print(i.get_text())
        #print(starsign)
        if i.get_text()==str(starsign):
            print(i['href'])
            url=urljoin(url,i['href'])
    self.get_color(url)
def get_color(self,url):
    self.browser.get(url)
    print(url)
    bsObj = BeautifulSoup(self.browser.page_source, "html.parser")
    description = bsObj.find("ul",{"class":"body-ul"})
    description= description.findAll("li")
    description=list(description[2].get_text())
    color=''.join(description[5:])
    self.luckycolor=color

5.因為每次啟動都抓一次過於耗時，因此引入將抓到的資訊匯出並以 nodejs 儲存

def start(self):
    now=datetime.now().strftime("%Y-%m-%d-%H-%M-%S")  #判別距離上次抓取資料是否過去一天
    now=now.split('-')
    with open("data.json", "r") as f:
        data=json.load(f)
    f.close()
    before=data['updateTime'].split('-')
    if self.oneday(now,before):
        self.get_allstarsign()
def writedata(self):  #寫入資料至檔案
    self.data["updateTime"] = datetime.now().strftime("%Y-%m-%d-%H-%M-%S")
    with open("data.json", "w",encoding='Utf-8') as f:
        json.dump(self.data,f)
    f.close()

主要 telegrambo 指令介紹: +off - 關機 #呼叫updater.stop()停止telegrambot self.updater.stop() +luckycolor - 查詢星座幸運色依照使用者輸入的星座查詢幸運色，若使用者衣服與幸運色相同則恭喜，若不同則噴水逞罰，最後會用 LED 顯示查詢到的幸運色同時傳送給使用者

def luckycolor(self,bot,update):
    message=update.message
    starsign=list(message['text'])
    starsign=starsign[12:]
    starsign=''.join(starsign)
    print(starsign)
    if starsign=="":
        update.message.reply_text(text='請在指令後方加入星座')
        return
    mysearch=crawler.Fetch()  #呼叫crawler.py 去抓你輸入的星座
    if mysearch.isin(starsign):
        update.message.reply_text(text='稍等一下，正在查詢....')
        with open("data.json", "r") as f:
            data=json.load(f)
        f.close()
        update.message.reply_text(text='今天'+starsign+'的幸運顏色是: '+str(data['starsign'][starsign]))
        mysearch.end()
    else:
        update.message.reply_text(text='沒有'+starsign+'這個星座')
    #self.yourluckyday(str(data['starsign'][starsign]))
    searchcolor=str(data['starsign'][starsign])
    #detectcolor.detector()
    mycam=ReadWebcam.color()
    out=mycam.run()                                 #用webcam抓看到的顏色返還RGB
    mydetector=detectcolor.detector(out[0],out[1],out[2])  #輸入RGB返還一個顏色(中文字)
    color=mydetector.test()
    if(color==searchcolor):
        update.message.reply_text(text="你今天很幸運喔")
    else:
        update.message.reply_text(text="今天不是你的幸運日喔")
        mymotor=motor.motor()
        mymotor.blink(self.water)            #噴self.water的水量
    myled=LED.LED()                      #將RGB傳給 LED
    myled.start(5,out[0],out[1],out[2])

+spray - 立即噴水

mymotor=motor.motor()
mymotor.blink(self.water)

+set_waterpw - 設定 self.water +hi -跟使用者打招呼從 updater 抓使用者的姓名跟他打招呼

message = update.message
chat = message['chat']
update.message.reply_text(text='HI  ' + str(chat['first_name'])+' '+str(chat['last_name']))

+whatcolor - 觀察顏色回傳 RGD 呼叫 Readwebcam 回傳看到的顏色 +blink - 依照觀察顏色亮燈

遇到的問題

webcam 感測顏色沒有到很準確 [待解決]
- 需要很靠近攝像頭
- 且多數感測出來的會是「白色」
telegram bot 問題 [已解決] - 安裝 Chromedriver 裝到 Linux 64 位元版但 Raspberry Pi 是 Arm64
- 爬蟲爬太慢，跑太久....
- 每天都會先爬蟲爬一次，把資料儲存下來，加快之後的查詢速度
LED 問題 [待解決]
- 色域不夠廣，僅能顯示部分顏色
- 線有時候較不靈敏，可能某一R、G、B 感測不良
