基于树莓派csi摄像头实时仓库谷物计数和仓库温湿度和烟雾检测系统的代码

这个项目涉及到多个模块，需要分别进行开发。以下是基本的代码结构和思路：

1. 树莓派连接CSI摄像头：

import cv2

# 初始化摄像头
cap = cv2.VideoCapture(0)
# 设置分辨率
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 640)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)

while True:
    # 读取摄像头画面
    ret, frame = cap.read()
    if not ret:
        break
        
    # 显示画面
    cv2.imshow("CSI Camera", frame)
    
    # 按下q键退出
    if cv2.waitKey(1) == ord('q'):
        break

# 释放摄像头资源
cap.release()
cv2.destroyAllWindows()

2. 图像处理和物体计数：

import cv2

# 初始化摄像头
cap = cv2.VideoCapture(0)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 640)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 480)

# 初始化背景
bg_subtractor = cv2.createBackgroundSubtractorMOG2()

# 初始化计数器
count = 0

while True:
    ret, frame = cap.read()
    if not ret:
        break
        
    # 背景差分
    fg_mask = bg_subtractor.apply(frame)
    
    # 二值化
    _, binary = cv2.threshold(fg_mask, 40, 255, cv2.THRESH_BINARY)
    
    # 轮廓检测
    contours, _ = cv2.findContours(binary, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
    
    # 绘制轮廓
    for contour in contours:
        x, y, w, h = cv2.boundingRect(contour)
        if w > 30 and h > 30:
            cv2.rectangle(frame, (x, y), (x+w, y+h), (0, 0, 255), 2)
            count += 1
    
    # 显示画面和计数
    cv2.putText(frame, "Count: {}".format(count), (10, 30), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 0, 255), 2)
    cv2.imshow("CSI Camera", frame)
    
    if cv2.waitKey(1) == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

3. 温湿度检测：

import Adafruit_DHT

# 温湿度传感器型号和引脚
sensor = Adafruit_DHT.DHT11
pin = 4

while True:
    # 读取温湿度
    humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
    if humidity is not None and temperature is not None:
        print('Temperature: {:.1f} C\tHumidity: {:.1f} %'.format(temperature, humidity))
    else:
        print('Failed to read temperature and humidity!')
        
    # 等待1秒
    time.sleep(1)

4. 烟雾检测：

import RPi.GPIO as GPIO
import time

# 烟雾传感器引脚
detection_pin = 17

# 初始化GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(detection_pin, GPIO.IN)

while True:
    # 读取烟雾状态
    smoke_detected = GPIO.input(detection_pin)
    if smoke_detected:
        print('Smoke detected!')
    else:
        print('No smoke detected.')
        
    # 等待1秒
    time.sleep(1)

以上是基本的代码结构和思路，具体的实现需要根据硬件和传感器的具体情况进行调整和优化。
