import numpy as np
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Dense, Dropout
# 假設資料結構 [時間, 魚狀態, pH, 溫度, 溶氧量, 餵食量]
data = np.array([
[1, 0.8, 7.5, 26, 8.0, 50],

你可以使用 Flask 或 Django 框架來建立一個 Web 應用,讓用戶可以通過瀏覽器或手機應用控制和監控餵魚系統。
from flask import Flask, render_template, request
import threading
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/feed', methods=['POST'])
def feed():
amount = int(request.form['amount'])
threading.Thread(target=feed_fish, args=(amount,)).start()
return f"正在餵食 {amount} 次。"
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000)

這部分代碼負責從多個攝像頭獲取視頻流並顯示。以下是詳細的代碼解釋:
import cv2
import threading
def stream_camera(camera_id, window_name):
cap = cv2.VideoCapture(camera_id)
while True:
ret, frame = cap.read()
if not ret:
break
cv2.imshow(window_name, frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
camera_threads = []
for i in range(3): # 假設有3個攝像頭
t = threading.Thread(target=stream_camera, args=(i, f'Camera {i}'))
t.start()
camera_threads.append(t)
for t in camera_threads:
t.join()
cv2.VideoCapture(camera_id)
:初始化攝像頭。cap.read()
:讀取攝像頭捕獲的畫面。cv2.imshow(window_name, frame)
:顯示畫面。threading.Thread
來並行處理多個攝像頭視頻流。這部分代碼負責使用 YOLO 模型進行魚的行為檢測:
import cv2
from yolonas import YOLOv8
# 初始化 YOLO-NAS 模型
model = YOLOv8("yolonas_large.pt")
def analyze_fish_behavior(video_path):
cap = cv2.VideoCapture(video_path)
while cap.isOpened():
ret, frame = cap.read()
if not ret:
break
results = model.predict(frame)
for result in results:
x1, y1, x2, y2, confidence, class_id = result
label = model.class_names[class_id]
# 畫出檢測框與標籤
cv2.rectangle(frame, (x1, y1), (x2, y2), (0, 255, 0), 2)
cv2.putText(frame, f"{label} {confidence:.2f}", (x1, y1 - 10), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (0, 255, 0), 2)
cv2.imshow('Fish Behavior', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
# 假設視頻文件來自實時流
analyze_fish_behavior("fish_tank_stream.mp4")
YOLOv8("yolonas_large.pt")
:載入預訓練的 YOLO-NAS 模型。model.predict(frame)
:對每一幀進行物體檢測,返回檢測結果。這部分代碼使用 LSTM 模型來預測未來的餵食量:
import numpy as np
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Dense, Dropout
# 假設資料結構 [時間, 魚狀態, pH, 溫度, 溶氧量, 餵食量]
data = np.array([
[1, 0.8, 7.5, 26, 8.0, 50],
[2, 0.7, 7.6, 26.5, 8.1, 45],
# 更多數據
])
# LSTM 模型設計
model = Sequential()
model.add(LSTM(128, return_sequences=True, input_shape=(data.shape[1] - 1, 1)))
model.add(Dropout(0.2))
model.add(LSTM(64))
model.add(Dense(1, activation='linear'))
model.compile(optimizer='adam', loss='mse')
# 假設訓練數據
X = data[:, :-1].reshape((data.shape[0], data.shape[1] - 1, 1))
y = data[:, -1]
# 模擬訓練
model.fit(X, y, epochs=200, batch_size=32)
# 預測下一次的餵食量
future_environment = np.array([[3, 0.75, 7.7, 27, 8.2]]).reshape((1, 5, 1))
predicted_feeding = model.predict(future_environment)
print(f"預測餵食量: {predicted_feeding[0][0]}")
Sequential()
:建立 LSTM 模型。model.add(LSTM(...))
:添加 LSTM 層來處理序列數據。model.fit(X, y)
:訓練模型。model.predict(future_environment)
:使用模型進行未來餵食量預測。這部分代碼控制餵食裝置,並讀取環境感測器數據:
import RPi.GPIO as GPIO
import time
import Adafruit_DHT # 假設使用 DHT22 感測器
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
# 假設使用 DHT22 來獲取環境溫濕度
def read_environment():
humidity, temperature = Adafruit_DHT.read_retry(Adafruit_DHT.DHT22, 4)
return humidity, temperature
def feed_fish(amount):
for _ in range(amount):
GPIO.output(18, GPIO.HIGH)
time.sleep(0.5)
GPIO.output(18, GPIO.LOW)
time.sleep(0.5)
# 獲取環境數據並餵食
humidity, temperature = read_environment()
print(f"環境溫度: {temperature}, 濕度: {humidity}")
predicted_feeding_amount = int(predicted_feeding[0][0])
feed_fish(predicted_feeding_amount)
GPIO.setup(18, GPIO.OUT)
:設置 GPIO 腳位來控制餵食裝置。Adafruit_DHT.read_retry(...)
:讀取溫濕度數據。feed_fish(amount)
:根據預測餵食量來控制餵食裝置。這部分代碼設置了基本的 Flask Web 應用來遠程控制餵食:
from flask import Flask, render_template, request
import threading
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
@app.route('/feed', methods=['POST'])
def feed():
amount = int(request.form['amount'])
threading.Thread(target=feed_fish, args=(amount,)).start()
return f"正在餵食 {amount} 次。"
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000)
Flask(__name__)
:初始化 Flask 應用。@app.route('/')
:根路由,渲染首頁模板。@app.route('/feed', methods=['POST'])
:處理餵食請求。這個系統的設計涵蓋了從視頻監控、行為檢測、環境感測、餵食預測到遠程控制的全面功能。每個模塊都可以根據實際需要進行調整和擴展。
