opencv水果计数

以下是基于Pycharm编程平台与opencv开源库实现水果种类的简单识别与计数的步骤：

1. 导入必要的库和模块

import cv2
import numpy as np

2. 读取图片并进行预处理

img = cv2.imread('fruit.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray, (5, 5), 0)
ret, thresh = cv2.threshold(blur, 60, 255, cv2.THRESH_BINARY)

3. 查找轮廓并绘制

contours, hierarchy = cv2.findContours(thresh, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE)
cv2.drawContours(img, contours, -1, (0, 0, 255), 2)

4. 计算水果数量

fruit_count = len(contours)
print("水果数量为：", fruit_count)

5. 显示结果

cv2.imshow('result', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
