树莓派自带针对camera的bash命令还是很实用的。官网有介绍如何使用。
raspistill -o cam.jpg
raspistill -t 30000 -tl 2000 -o image%04d.jpg
raspivid 捕获视频
raspivid -o video.h264 -t 10000
如果想在Python中调用camera功能,推荐使用这个
sudo apt-get update
sudo apt-get install python-picamera
import picamera camera = picamera.PiCamera() camera.capture(‘image.jpg‘)
具体看github上的说明吧,很详细了。ReadMe
直接贴代码吧,很easy。
import os from time import sleep from datetime import datetime, timedelta from picamera import PiCamera from bypy import ByPy def wait(delay_minute = 1): next_time = (datetime.now() + timedelta(minutes=delay_minute)).replace(second=0, microsecond=0) delay = (next_time - datetime.now()).seconds sleep(delay) by=ByPy() camera = PiCamera() camera.start_preview() wait() for filename in camera.capture_continuous(‘img{timestamp:%Y-%m-%d-%H-%M}.jpg‘): print(‘capture %s‘ % filename) by.upload(filename) os.remove(filename) wait()
每隔1分钟拍一次,自动上传到百度网我的应用数据/bypy文件夹下
