7、TPU 手机操控Google Edge TPU开发板

1、首先进入TPU终端；具体操作参考：https://model.gravitylink.com/doc/guide.html#/

 mkdir /home/mendel/edge_tpu_server 
 cd /home/mendel/edge_tpu_server
 wget http://glink-model-store.oss-cn-hongkong.aliyuncs.com/server/server

然后修改下载的文件，设置成可执行的权限

sudo chmod a+x server

2、然后设置默认开机自动启动，打开配置文件，然后在文件中添加两句，保存退出

sudo vim /etc/bash.bashrc

设置到配置文件中

cd /home/mendel/edge_tpu_server
nohup ./server >> /home/mendel/edge_tpu_server/server.log &

{ 官方手册给出了另一种方法：

首先，设置启动服务文件；

mendel@tuned-ibis:~/edge_tpu_server$ vim tpu.service

然后写入文件内容

[Unit]
Description=Edge TPU Server Demo
After=weston.target

[Service]
Environment=DISPLAY=:0
PAMName=login
Type=simple
Restart=always
User=mendel
WorkingDirectory=/home/mendel/edge_tpu_server
#RootDirectoryStartOnly=true
ExecStart=/home/mendel/edge_tpu_server/server

[Install]
WantedBy=multi-user.target

然后建立软连接，启动服务

mendel@tuned-ibis:~/edge_tpu_server$ sudo ln -s /home/mendel/edge_tpu_server/tpu.service /lib/systemd/system
mendel@tuned-ibis:~/edge_tpu_server$ sudo systemctl daemon-reload
mendel@tuned-ibis:~/edge_tpu_server$ sudo systemctl enable tpu.service
Created symlink /etc/systemd/system/multi-user.target.wants/tpu.service → /home/mendel/edge_tpu_server/tpu.service.
mendel@tuned-ibis:~/edge_tpu_server$ sudo service tpu start
mendel@tuned-ibis:~/edge_tpu_server$ sudo reboot

}

之后将显示我们设置两种方式都都成功了（任选一种即可）

3、然后在个人手机上安装apk链接：https://pan.baidu.com/s/1FdhyT5_3tuxsLBXRwWJ_xg 密码：k0w7

{ 

涉及到摄像头问题，本想使用用手机摄像头作为usb摄像头上使用

在手机终端安装app链接：https://pan.baidu.com/s/1n84P7vDdW5mocdFrhkJEzg 密码：ryut

然后在网页输入http://IP:port/

用户名和密码即可显示手机摄像头的图像；

下一步希望链接TPU访问（手机充当）摄像头

import cv2
url = "http://admin:admin@IP:PORT"
cap = cv2.VideoCapture(url)
while True:
    ret,frame=cap.read()
    cv2.imshow("frame",frame)
    if cv2.waitKey(1)&0xFF==ord('q'):
       break
cap.release()
cv2.destroyAllWindows()

}

注册账户名和密码，之后进行添加设备和填入TPU的IP

然后添加模型 ;就ok～～～
