如何判断树莓派型号

可以到系统上通过此处方法来查看，或者直接看外观这边有标明

Raspberry Pi 3 Model B V1.2
Raspberry 2015
FCC ID：2ABCB-RP132
IC:20953-RP132
FCC全称是Federal Communications Commission，中文为美国联邦通信委员会。于1934年根据Communications Act建立，是美国政府的一个独立机构，直接对国会负责。FCC通过控制无线电广播、电视、电信、卫星和电缆来协调国内和国际的通信。涉及美国50多个州、哥伦比亚以及美国所属地区为确保与生命财产有关的无线电和有线通信产品的安全性，FCC的工程技术部（Office of Engineering and Technology）负责委员会的技术支持，同时负责设备认可方面的事务。许多无线电应用产品、通讯产品和数字产品要进入美国市场，都要求FCC的认可。

所以我手上的是这款：

Raspberry Pi 3 Model B 树莓派三代B型
1.4GHZ CPU、低功耗蓝牙4.1、1G内存

现在只有一个壳子，我手上还缺5v/2A电源及电源线、HDMI转VGA线（其实还好，我那边有HDMI的显示屏）

但是着一切都不是问题，树莓派有use接口，并且我可以通过PuTTY连接树莓派。

因为不知道这个系统是谁的，而且出现上电没有HDMI输出的现象

所以我们现在先在linux下对树莓派烧录系统

shumeipai.nxez.com/download

shumeipai.nxez.com/2013/12/08/linux-command-line-burn-raspberry-pi-mirror-to-sd-card.html

我首先用linux的dd，因为SD卡的分区显示的是mmcblk0p1和mmcblk0p2，我的dd指令是sudo dd bs=4M if=2019-09-26-raspbian-buster.img of=/dev/mmcblk0p的时候会提示

dd: 写入'/dev/mmcblk0p' 出错: 设备上没有空间
记录了474+0 的读入
记录了473+0 的写出
1988042752 bytes (2.0 GB, 1.9 GiB) copied, 51.1839 s, 38.8 MB/s

所以我改成sudo dd bs=4M if=2019-09-26-raspbian-buster.img of=/dev/mmcblk0

成功了

车牌识别

https://www.cnblogs.com/subconscious/p/3979988.html

为了避免系统中安装的老版本opencv对编译的影响，需要在 CMakeLists.txt 中修改：

set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "/usr/local/opt/opencv3")

改为：


if (CMAKE_SYSTEM_NAME MATCHES "Darwin")set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} "/home/asber/opencv-3.2.0")
endif ()

但是make的时候出错了

现在有两个选择，继续debug此文件，进去和群里面的人一起商讨，但是我们现在选择下面这个工程，其识别车型也更多。

HyperLPR

https://github.com/zeusees/HyperLPR

https://github.com/armaab/hyperlpr-train

基于深度学习高性能中文车牌识别

支持python3,支持Windows Mac Linux 树莓派等。

CPP 依赖

Opencv 3.4 以上版本

查看linux下的opencv安装版本：

pkg-config opencv --modversion

我的是3.2.0

安装一下3.4版本的opencv

ubuntu16.04上的OpenCV多版本共存

ubuntu opencv3.4.6安装

注意（如果你安装了anaconda然后make出错）：https://www.cnblogs.com/dinghongkai/p/11288338.html）

[ 50%] Linking CXX shared library ../../lib/libopencv_objdetect.so
[ 50%] Built target opencv_objdetect
[ 50%] Linking CXX shared library ../../lib/libopencv_stitching.so
[ 50%] Built target opencv_stitching
Makefile:162: recipe for target 'all' failed
make: *** [all] Error 2

make报错，可能是cmake的参数问题？还是cmake的版本问题？（更新过）还是anaconda的问题？

Linux/Mac 编译

仅需要的依赖OpenCV 3.4 (需要DNN框架)

cd Prj-Linux
mkdir build 
cd build
cmake ../
sudo make -j

CPP demo

#include "../include/Pipeline.h"
int main(){pr::PipelinePR prc("model/cascade.xml","model/HorizonalFinemapping.prototxt","model/HorizonalFinemapping.caffemodel","model/Segmentation.prototxt","model/Segmentation.caffemodel","model/CharacterRecognization.prototxt","model/CharacterRecognization.caffemodel","model/SegmentationFree.prototxt","model/SegmentationFree.caffemodel");//定义模型文件cv::Mat image = cv::imread("test.png");std::vector<pr::PlateInfo> res = prc.RunPiplineAsImage(image,pr::SEGMENTATION_FREE_METHOD);//使用端到端模型模型进行识别 识别结果将会保存在res里面for(auto st:res) {if(st.confidence>0.75) {std::cout << st.getPlateName() << " " << st.confidence << std::endl;//输出识别结果 、识别置信度cv::Rect region = st.getPlateRect();//获取车牌位置cv::rectangle(image,cv::Point(region.x,region.y),cv::Point(region.x+region.width,region.y+region.height),cv::Scalar(255,255,0),2);//画出车牌位置}}cv::imshow("image",image);cv::waitKey(0);return 0 ;
}

而且这个文档带UI界面的工程是windows下的

还是试一试python版把

windows中python版本的使用教程 linux下的与之类似

所需依赖：

pip install Keras
pip install Theano
pip install Numpy
pip install Scipy
pip install opencv-python
pip install scikit-image
pip install pillow
pip install tensorflow

sudo cp -r /home/asber/platerecong/HyperPR/HyperLPR/hyperlpr_py3 /home/asber/anaconda3/lib/hyperlpr

然后发现……果然不行阿，到底如何将这个库放到linux下的anaconda呢？

然后我TM惊奇的发现，直接

pip install hyperlpr

就可以用了。。。

但是发现？？

竟然还是没有检测出来，后来群里小伙伴说直接运行里面的demo.py就可以为试了一下，（demo中2.jpg变成了2_.jpg搞得一直抱错）既然跑出来了，我们就来分析一下这个程序的逻辑关系把。

demo.py的逻辑关系

import sys
reload(sys)
sys.setdefaultencoding("utf-8")#这个是计时函数，其实也是运行这个识别的核心代码
import timedef SpeedTest(image_path):grr = cv2.imread(image_path)model = pr.LPR("model/cascade.xml", "model/model12.h5", "model/ocr_plate_all_gru.h5")model.SimpleRecognizePlateByE2E(grr)t0 = time.time()for x in range(20):model.SimpleRecognizePlateByE2E(grr)t = (time.time() - t0)/20.0print "Image size :" + str(grr.shape[1])+"x"+str(grr.shape[0]) +  " need " + str(round(t*1000,2))+"ms"#这个就是在图片上的某个框中标注车牌号

import cv2
import numpy as np
grr = cv2.imread(r"images_rec/2.jpg")
cv2.namedWindow('image',0)
cv2.imshow('image',grr)
cv2.waitKey()
cv2.destroyAllWindows()
model = pr.LPR(r"model/cascade.xml",r"model/model12.h5","model/ocr_plate_all_gru.h5")
for pstr,confidence,rect in model.SimpleRecognizePlateByE2E(grr):if confidence>0.7:image = drawRectBox(grr, rect, pstr+" "+str(round(confidence,3)))print "plate_str:"print pstrprint "plate_confidence"print confidencecv2.imshow("image",image)
cv2.waitKey(0)SpeedTest("images_rec/2_.jpg")

代码很好理解，model的初始化列表需要1.检测模型2.识别模型3.不知道

我们还是看一看HyperLPRLite这个py把

模型资源说明

cascade.xml- 目前效果最好的cascade检测模型
cascade_lbp.xml 召回率效果较好，但其错检太多
char_chi_sim.h5 Keras模型-可识别34类数字和大写英文字使用14W样本训练
char_rec.h5 Keras模型-可识别34类数字和大写英文字使用7W样本训练
ocr_plate_all_w_rnn_2.h5 基于CNN的序列模型
ocr_plate_all_gru.h5 基于GRU的序列模型从OCR模型修改，效果目前最好但速度较慢，需要20ms。
plate_type.h5 用于车牌颜色判断的模型
model12.h5 左右边界回归模型

其实SimpleRecognizePlateByE2E大概就是首先检测出车牌所在的位置，然后fine turn，然后识别字符。

测试OK

在树莓派上安装环境

ssh

https://blog.csdn.net/perry0418/article/details/80994840

2019/11/2日早上早早来到协会，没有人的协会速度超快，但是还是出现问题然后没下好tensorflow，找原因找了一会儿协会又没有网了。。干脆等等到学校下载好了。

ubuntu16.04 ssh配置和树莓派远程登录

sudo gedit /etc/ssh/sshd_config

#LoginGraceTime 2m
#PermitRootLogin prohibit-password
PermitRootLogin yes
StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

Permission denied, please try again 一直提示这个，首先我们都是同一个局域网（手机热点）其次ssh的环境弄好了。sshd_config可能是问题之一。

方案一：修改/etc/ssh/sshd_config ---无效：

PermitRootLogin yes
StrictModes yes

都对了然后service ssh restart 还是不行 = =

然后我修改了both root和pi的密码，还是拒绝。

pip install scipy also get this

install --record /tmp/pip-record-XgluiL/install-record.txt --single-version-externally-managed --compile --user --prefix=" failed with error code 1 in /tmp/pip-install-B9SdP1/scipy

so it seems that you derectly download scipy by pip

so I use sudo apt-get install python-scipy (seems once I done this before)
