1.結構光相機標定軟件
結構光相機標定是一件十分復雜的過程，所幸布朗大學開源了一套投影儀攝像機標定系統(Projector-Camera Calibration/3D Scanning Software)?
官方地址：?Projector-Camera Calibration / 3D Scanning Software
官網提供了Window和Apple OSX編譯好的標定軟件，很不幸的是，版本比較老舊，僅支持Windows 7 x64，Opencv也是比較老舊的OpenCV 2.4.11,沒有提供Linux版本的,你想在Ubuntu成功運行還是要采坑的。
下面手把手教你，如何在Ubuntu上，編譯源碼
?當然，若你不想經歷填坑的痛苦，可以直接下載本人已經修改好的源碼，已經包括Opencv，TIFF，scan3d-capture-src-2015等源碼，直接使用即可

?關于如果實現三維重建，請查看下一篇博客《結構光三維重建-3D Scanning Software實現三維重建》：https://panjinquan.blog.csdn.net/article/details/121113787
2. 依賴環境
| 庫 | 本地使用版本 | 說明 |
| Ubuntu | Ubuntu18.04 | 本機系統 |
| tiff | tiff-4.3.0 (tiff-4.0.x以上亦可) | opencv編譯需要TIFF |
| OpenCV | opencv-4.3.0 (opencv-3.2.0.x以上亦可) | 3D Scanning Software需要用的OpenCV |
| ?Qt | Qt 5.5.1(Qt 5.0.x以上亦可) | 3D Scanning Software的UI是使用Qt布局的 |
2.1 安裝TIFF
下載地址：Index of /libtiff/?，tiff-4.0.4.tar.gz (tiff-4.0.x以上亦可)
? ?# 解壓tar -zxvf tiff-4.0.4.tar.gz# 進入tiff目錄./configuremakesudo make install2.2 安裝OpenCV
(1) 源碼編譯
安裝 OpenCV 所需要的庫，在終端依次執行以下命令：
sudo apt-get update sudo apt-get install build-essential sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev官網下載 OpenCV 4.3.0 的源代碼（下載地址：Releases - OpenCV）并解壓到 opencv4.3.0 目錄，然后進入到 opencv4.3.0 的目錄，執行
mkdir build cd build配置 OpenCV 工程文件
sudo cmake -DBUILD_TIFF=ON -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..PS: 編譯選項中，一定要加上-DBUILD_TIFF=ON， 因為標定系統源碼需要用到TIFF，否則會出現TIFFReadDirectory@LIBTIFF_4.0’未定義的引用的錯誤
如果執行命令時出現下載 ippicv 失敗，可以參考文章解決：ubuntu編譯安裝opencv3.3+python3
編譯安裝
sudo make install編譯OpenCV，加上-DBUILD_TIFF=ON選項后，可能會出現以下各種錯誤
(2) 編譯OpenCV常見錯誤
1.error: ‘O_RDONLY’ undeclared
/home/dm/app/opencv-4.3.0/3rdparty/libtiff/tif_close.c: In function ‘TIFFCleanup’:
/home/dm/app/opencv-4.3.0/3rdparty/libtiff/tif_close.c:50:23: error: ‘O_RDONLY’ undeclared (first use in this function)
? if (tif->tif_mode != O_RDONLY)
?解決方法：在opencv-4.3.0/3rdparty/libtiff/tiff.h頭文件添加頭文件#include <fcntl.h>
.... #ifndef _TIFF_ #define _TIFF_#include "tiffconf.h" #include <fcntl.h> ....PS：如果還有類似的錯誤，請在發生錯誤的該源碼文件中加入頭文件#include <fcntl.h>
2.error: conflicting declaration of ‘int _TIFF_snprintf_f
In file included from /home/dm/app/opencv-4.3.0/3rdparty/libtiff/tif_stream.cxx:28:0:
/home/dm/app/opencv-4.3.0/3rdparty/libtiff/tiffiop.h:60:18: error: conflicting declaration of ‘int _TIFF_snprintf_f(char*, size_t, const char*, ...)’ with ‘C’ linkage
?#define snprintf _TIFF_snprintf_f
?解決方法：聲明存在沖突，應該Linux已經存在了，所以可以注釋opencv-4.3.0/3rdparty/libtiff/tiffiop.h源碼的下面兩行：
//#define snprintf _TIFF_snprintf_f
//extern int snprintf(char* str, size_t size, const char* format, ...);
3.error: ‘strchr’ was not declared in this scope
/home/dm/app/opencv-4.3.0/3rdparty/libtiff/tif_stream.cxx:361:6: error: ‘strchr’ was not declared in this scope
? if( strchr(mode, 'w') ) {
? ? ? ^~~~~~
/home/dm/app/opencv-4.3.0/3rdparty/libtiff/tif_stream.cxx:361:6: note: suggested alternative: ‘strtoq’
? if( strchr(mode, 'w') ) {
?解決方法：在發生錯誤的該源碼文件中opencv-4.3.0/3rdparty/libtiff/tif_stream.cxx加入頭文件?#include <string.h>
2.3 安裝QT5
官網下載：https://download.qt.io/archive/qt/
清華鏡像：https://mirrors.tuna.tsinghua.edu.cn/qt/official_releases/qt/
下載qt-opensource-linux-x64-5.12.4.run (Qt 5.0.x以上亦可)
對于Linux系統，Qt官方的安裝包總是假定C++編譯器compiler、調試器debugger、生成器make以及其他開發工具 由該操作系統自己提供，另外構建Qt圖形界面程序還需要OpenGL庫文件（擴展名為 .a 和 .so）和頭文件（擴展名為 .h）， OpenGL的開發庫也是需要操作系統自己提供。所以在安裝Qt官方run文件之前，必須先安裝好Linux系統自己軟件源里面 的GNU開發工具集和OpenGL開發庫。下面針對三類 Linux 操作系統安裝相應的GNU開發工具集和OpenGL開發庫， 請注意安裝軟件都需要root權限，并且要聯網安裝。
sudo apt-get install build-essential libgl1-mesa-dev給QT安裝文件可執行權限：
chmod +x qt-opensource-linux-x64-5.12.4.run安裝
./qt-opensource-linux-x64-5.12.4.runQT安裝教程，可參考：https://blog.csdn.net/a435262767/article/details/99317188?
安裝后，終端輸入qmake,會出現下截圖，表示QT已經安裝成功：
3. 編譯標定源碼：3D Scanning Software
（1）源碼編譯
?官方地址：?Projector-Camera Calibration / 3D Scanning Software? ，把下面的內容都下載下來
解壓scan3d-capture-src-2015.zip
在project/scan3d-capture.pri，配置qmake的opencv路徑：
INCLUDEPATH += /usr/local/include/opencv4 \/usr/local/include/opencv4/opencv2LIBS += /usr/local/lib/libopencv_* \?配置好opencv，就可以開始編譯標定源碼了：
cd scan3d-capture-src mkdir build cd build qmake ../project # 使用QT的qmake進行build make # (or nmake to build with Microsoft Visual Studio)每什么意外的話，直接make會出現各種opencv錯誤的，究其原因是opencv版本對應不上，源碼使用的OpenCV 2.4.11,如果需要更高版本的OpenCV，如OpenCV4.3.0，則需要改動地方挺多
（2）常見的錯誤和解決方法
（1）?error: ‘CV_BGR2GRAY’ was not declared in this scope
?將所有CV_BGR2GRAY改為cv::COLOR_BGR2GRAY
//cvtColor(rgb_image, gray_image, CV_BGR2GRAY); // 舊版本 cvtColor(rgb_image, gray_image, cv::COLOR_BGR2GRAY);// 新版本（2）error: ‘CV_RANSAC’ was not declared in this scope
?同上，將CV_RANSAC改為cv::RANSAC
//cv::Mat H = cv::findHomography(img_points, proj_points, CV_RANSAC); cv::Mat H = cv::findHomography(img_points, proj_points, cv::RANSAC);（3）error: ‘CV_TERMCRIT_EPS’ was not declared in this scope
?將參數CV_TERMCRIT_EPS + CV_TERMCRIT_ITER改為cv::TermCriteria::EPS + cv::TermCriteria::MAX_ITER
// cv::cornerSubPix(gray_image, cam_corners, cv::Size(11, 11), cv::Size(-1, -1), // cv::TermCriteria(CV_TERMCRIT_EPS + CV_TERMCRIT_ITER, 30, 0.1)); cv::cornerSubPix(gray_image, cam_corners, cv::Size(11, 11), cv::Size(-1, -1),cv::TermCriteria(cv::TermCriteria::EPS + cv::TermCriteria::MAX_ITER, 30, 0.1));（4）error: no matching function for call to ‘stereoCalibrate
修改參數：cv::stereoCalibrate如下
// calib.stereo_error = cv::stereoCalibrate(world_corners_active, camera_corners_active, projector_corners_active, calib.cam_K, calib.cam_kc, calib.proj_K, calib.proj_kc, // imageSize /*ignored*/, calib.R, calib.T, E, F, // cv::TermCriteria(cv::TermCriteria::COUNT + cv::TermCriteria::EPS, 150, DBL_EPSILON), // cv::CALIB_FIX_INTRINSIC /*cv::CALIB_USE_INTRINSIC_GUESS*/ + cal_flags); calib.stereo_error = cv::stereoCalibrate(world_corners_active, camera_corners_active, projector_corners_active, calib.cam_K, calib.cam_kc, calib.proj_K, calib.proj_kc,imageSize /*ignored*/, calib.R, calib.T, E, F,cv::CALIB_FIX_INTRINSIC /*cv::CALIB_USE_INTRINSIC_GUESS*/ + cal_flags,cv::TermCriteria(cv::TermCriteria::COUNT + cv::TermCriteria::EPS, 150, DBL_EPSILON));（5）error: ‘CV_CAP_PROP_FRAME_WIDTH’ was not declared in this scope
（6）error: ‘CV_CAP_PROP_FRAME_HEIGHT’ was not declared in this scope
?這些錯誤都是因為版本差異問題導致的，需要改用的地方很多
修改頭文件VideoInput.hpp：
//CvCapture * _video_capture; cv::VideoCapture * _video_capture;修改源文件VideoInput.cpp,其他地方也參考修改
//cvSetCaptureProperty(_video_capture, CV_CAP_PROP_FRAME_WIDTH, width); //cvSetCaptureProperty(_video_capture, CV_CAP_PROP_FRAME_HEIGHT, height); _video_capture->set(cv::CAP_PROP_FRAME_WIDTH, width); _video_capture->set(cv::CAP_PROP_FRAME_HEIGHT, height);（7）error: ‘IplImage’ was not declared in this scope?
?源碼修改如下：
while(_video_capture && !_stop && error<max_error){IplImage * frame = cvQueryFrame(_video_capture);if (frame){ //okerror = 0;emit new_image(cv::Mat(frame));}else{ //errorif (timer.elapsed()>warmup) {error++;}}/*************************改為****************************/while(_video_capture && !_stop && error<max_error){//IplImage * frame = cvQueryFrame(_video_capture);cv::Mat frame;//*_video_capture >> frame;_video_capture->read(frame);if (not frame.empty()){ //okerror = 0;emit new_image(cv::Mat(frame));}else{ //errorif (timer.elapsed()>warmup) {error++;}}}（7）?error: ‘cvReleaseCapture’ was not declared in this scope
如下修改：?
//cvReleaseCapture(&_video_capture);_video_capture->release();?（8）error: ‘CV_CAP_V4L2’ was not declared in this scope
將CV_CAP_V4L2修改為cv::CAP_V4L2
?（9）error: ‘cvCreateCameraCapture’ was not declared in this scope
修改如下?
//_video_capture = cvCreateCameraCapture(CLASS + index);_video_capture->open(CLASS + index);最終，最后。。。。。，NND，還有錯
?（10）VideoInput.cpp:(.text+0xb73)：對‘VideoInput::list_device_resolutions_v4l2(int, bool)’未定義的引用
//list = list_device_resolutions_v4l2(index, silent);list = list_device_resolutions_dshow(index, silent);OK，終于成功：
然后，你在 bin目錄就可以找到一個可執行文件：scan3d-capture，
運行他即可：
./scan3d-capture千呼萬喚始出來,終于見到這個界面了：
4.懶人必備
兄弟，如果，你不想經歷上面填坑的痛苦，可以直接下載本人已經修改好的源碼，已經包括Opencv，TIFF，scan3d-capture-src-2015等源碼，直接使用即可
下載地址：?https://download.csdn.net/download/guyuealian/36484460
?使用方法，如下：
## 安裝tiff-4.3.0
```bash
cd tiff-4.3.0
./configure
make
sudo make install
```
## 安裝OpenCV
已經把常見的錯誤，都修改了，可以直接build
```bash
cd opencv-4.3.0
bash build.sh
```
## 安裝QT5
```bash
sudo apt-get install build-essential libgl1-mesa-dev
chmod +x qt-opensource-linux-x64-5.12.4.run
