0. 环境
- win10 + python3
- pycharm
- esp32-cam http://192.168.4.1
1. 创建工程
File -> Create Project ->
-> Location: E:\Workspaces\PycharmProjects\esp32cam_opencv
-> Create
2. opencv hello
2.1 添加脚本
File -> New -> Python file -> opencv_hello.py
输入以下内容：
import cv2
image = cv2.imread('res00.jpg') # 读取图片到内存，注意文件地址
cv2.imshow('Phuket Island', image) # 在窗口中显示图片，第一个参数是窗口名称
cv2.waitKey() # 按任意键继续
2.2 安装插件
File -> Settings -> Project: esp32cam_opencv -> Python Interpreter -> +
-> opencv-python -> Install Package
-> OK
2.3 运行测试
右键 opencv_hello.py -> Run 'opencv_hello' ->
3. esp32 cam
3.1 修改 main.py
import cv2
url = "http://192.168.4.1:81/stream"
cap = cv2.VideoCapture(url)
while True:
ret, frame = cap.read()
cv2.imshow("frame", frame)
if cv2.waitKey(1) & 0xFF == ord("q"):
break3.2 安装插件
File -> Settings -> Project: esp32cam_opencv -> Python Interpreter -> +
