In this tutorial you will learn how to install ViSP from source on Jetson TX2 equipped with a Connect Tech Quasar Carrier board.

Note

ViSP is already packaged for linux Jetson. To know which version is available

$ apt-cache search libvisp

Installation instructions are provided in Tutorial: Installation from prebuilt packages for Linux Ubuntu/Debian

Concerning ViSP installation, we provide also other Tutorials.

Install prerequisites

This tutorial was tested with NVIDIA Jetson TX2 flashed with JetPack 4.6(rev3).

The first step is to setup and flash your Jetson for a Connect Tech Carrier Board following this tutorial. This could be achieved from a laptop running ubuntu 16.04 or 18.04.
The second step is to install NVIDIA SDK Components using this tutorial.
The third step consists in installing GNU g++ compiler, CMake and git. To this end connect to the Jetson and run.

$ sudo apt-get install build-essential cmake-curses-gui git wget

Create a workspace

First create a workspace that will contain all ViSP source, build, data set and optional 3rd parties. This workspace is here set to $HOME/visp-ws folder, but it could be set to any other location.

In a terminal, run:

$ echo "export VISP_WS=$HOME/visp-ws" >> ~/.bashrc
$ source ~/.bashrc
$ mkdir -p $VISP_WS

Quick ViSP installation

In this section, we give minimal instructions to build ViSP from source just to try ViSP without entering in Advanced ViSP installation.

Install a small number of recommended 3rd parties (knowing that OpenCV should be already installed if you follow this tutorial).

$ sudo apt-get install libx11-dev liblapack-dev libeigen3-dev libv4l-dev libzbar-dev libpthread-stubs0-dev libjpeg-dev libpng-dev

Get ViSP source code

$ cd $VISP_WS
$ git clone https://github.com/lagadic/visp.git

Create a build folder and build ViSP

$ mkdir -p $VISP_WS/visp-build
$ cd $VISP_WS/visp-build
$ cmake ../visp
$ make -j4

Set VISP_DIR environment variable

$ echo "export VISP_DIR=$VISP_WS/visp-build" >> ~/.bashrc
$ source ~/.bashrc

To have a trial, just jump to Install ViSP dataset before running some binaries that you just build or jump to Next tutorial. You can later come back to the Advanced ViSP installation.

Advanced ViSP installation

Install 3rd parties

ViSP is interfaced with several optional 3rd party libraries. Follow the link to see the complete list of Supported Third-Party Libraries.

Note: ViSP can be used without any third-party since all of them are optional. But obviously in this case, as we do not want to reinvent the wheel, some features implemented in third-party libraries will not be exploitable through ViSP. It is therefore possible to skip in a first time this section and start directly to Quick ViSP installation. Later, if you realize that a third-party library is missing, you can still install it, go back to the build folder, configure ViSP with CMake to detect the newly installed third-party library and build ViSP again as explained in How to take into account a newly installed 3rd party.

Recommended 3rd parties

We recommend to install the following 3rd parties:

OpenCV
libX11 to be able to open a window to display images
lapack and eigen to benefit from optimized mathematical capabilities
libv4l to grab images from usb or analogic cameras
libzbar to be able to detect QR codes
pthread library

Installation of the other recommended 3rd parties could be performed running:

$ sudo apt-get install libopencv-dev libx11-dev liblapack-dev libeigen3-dev libv4l-dev libzbar-dev libpthread-stubs0-dev libdc1394-22-dev

Install OpenCV from source

To be able to run the tutorial, you should install OpenCV from source, since some extra modules are required (cudev, cudaarithm and cudawarping are not included in libopencv-contrib-dev package). To do so, proceed as follows:

In VISP_WS, clone opencv and opencv_contrib repos:
$ mkdir -p $VISP_WS/3rdparty

$ cd $VISP_WS/3rdparty

$ git clone https://github.com/opencv/opencv

$ git clone https://github.com/opencv/opencv_contrib
Create build directory in opencv directory
$ cd opencv && mkdir build && cd build
To install opencv with extra modules, execute the following command:
$ cmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \

-DWITH_CUDA=ON \

-DBUILD_opencv_cudev=ON \

-DBUILD_opencv_cudaarithm=ON \

-DBUILD_opencv_cudawarping=ON ../
Note that if you want a more advanced way to configure the build process, you can use ccmake:
$ ccmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ../

At this point, you can check if cudev, cudaarithm and cudawarping extra modules are enabled as expected:

$ grep cudev version_string.tmp
"    To be built:                 ... cudev ...
$ grep cudaarithm version_string.tmp
"    To be built:                 ... cudaarithm ...
$ grep cudawarping version_string.tmp
"    To be built:                 ... cudawarping ...

If this is not the case, it means that something is wrong, either in CUDA installation, either in OpenCV configuration with cmake.

Launch build process:
$ make -j$(nproc)

$ sudo make install

librealsense 2.x 3rd party

If you have an Intel RealSense Depth camera (SR300 or D400 series), you may install librealsense 2.x in order to use vpRealSense2 class. Otherwise you can skip this section.

Installation instructions are given in the tutorial.

Note: Since our kernel is 4.12+ streaming Depth/IR/Color is supported and is provided out of the box. This means that the patches are not needed.

Following the tutorial, we recall the main steps here:

Unplug any connected Intel RealSense camera.

Install the packages required for librealsense build:

$ sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libgtk-3-dev cmake-curses-gui
$ sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev

Get librealsense from github:

$ cd $VISP_WS/3rdparty
$ git clone https://github.com/IntelRealSense/librealsense.git
$ cd librealsense

Run Intel Realsense permissions script located in librealsense root directory:
```
$ sudo ./scripts/setup_udev_rules.sh
```

Build and install librealsense

$ mkdir build
$ cd build
$ cmake .. -DBUILD_EXAMPLES=ON -DCMAKE_BUILD_TYPE=Release
$ make -j4
$ sudo make install

Connect your Realsense camera (we are using a D435) and check if you are able to acquire images running:
```
$ ./examples/capture/rs-capture
```

If you are able to visualize the images, it means that you succeed in librealsense installation.

libStructure 3rd party

If you have an Occipital Structure Core sensor (monochrome or color), you may install Occipital Structure SDK in order to use vpOccipitalStructure class. Otherwise you can skip this section.

Occipital Structure SDK contains libStructure pre-built library.

Download the SDK

Go to https://developer.structure.io/sdk/
Join the Developper program to be able to download the SDK.
Retrieve your invitation from https://developer.structure.io/sdk/retrieve
You'll then receive an email containing the link to the download page,
Download Structure SDK (Cross-Platform).
Extract the folder StructureSDK-CrossPlatform-0.9 from the downloaded file to the already created directory in $VISP_WS.

The SDK contains pre-built libraries for Linux, Windows and macOS. In order that ViSP detects Structure SDK header files and libraries, you have to set OCCIPITAL_STRUCTURE_DIR environment variable. Proceed as follows:

$ echo "export OCCIPITAL_STRUCTURE_DIR=$VISP_WS/StructureSDK-CrossPlatform-0.9" >> ~/.bashrc
$ source ~/.bashrc

Get ViSP source code

Get ViSP from GitHub repository using the following command

$ cd $VISP_WS
$ git clone https://github.com/lagadic/visp.git

We suppose now that ViSP source is in the directory $VISP_WS/visp.

Configure ViSP from source

These are the steps to configure ViSP from source with CMake:

In the workspace, create first a directory named visp-build that will contain all the build material; generated Makefiles, object files, output libraries and binaries.
```
$ mkdir $VISP_WS/visp-build
```
Enter the visp-build folder and configure the build:
```
$ cd $VISP_WS/visp-build
$ cmake ../visp
```
A more versatile way to configure the build is to use ccmake, the CMake GUI:
```
$ ccmake ../visp
```
The following image shows that this command allows to configure (just by pressing [c] key) the build in a more advanced way where some options could be easily turned ON/OFF. It allows also to see which are the 3rd parties that will be used. To generate the makefiles, just press [g] key in the ccmake gui.

Snapshot of the ccmake ../visp command used to configure ViSP.

Build and install ViSP libraries

To build ViSP libraries proceed with:

$ cd $VISP_WS/visp-build
$ make -j4
$ sudo make install

Build ViSP documentation

To build ViSP documentation, you have first to install Doxygen package:

$ sudo apt-get install doxygen graphviz texlive-latex-base

Then you can proceed with:

$ cd $VISP_WS/visp-build
$ cmake ../visp
$ make -j4 visp_doc

The generated documentation is then available in $VISP_WS/visp-build/doc/html/index.html

Note

To speed up generating online doc, particularly around formula rendering, you can use MatJax. To this end, install MathJax and build doc using:
```
$ npm install mathjax
$ cmake ../visp -DUSE_MATHJAX=ON
$ make -j4 visp_doc
```

It is also possible to generate a more complete documentation that includes also all the internal classes. This could be achieved setting CMake var ENABLE_FULL_DOC to ON like:
```
$ cmake ../visp -DENABLE_FULL_DOC=ON
$ make -j4 visp_doc
```

Set VISP_DIR environment var

In order to ease ViSP detection by CMake when ViSP is used as a 3rd party in an external project, like the one described in the Tutorial: How to create and build a project that uses ViSP and CMake on Unix or Windows, you may set VISP_DIR environment variable with the path to the VISPConfig.cmake file:

$ echo "export VISP_DIR=$VISP_WS/visp-build" >> ~/.bashrc
$ source ~/.bashrc

Install ViSP dataset

Some ViSP examples and tests require a data set that contains images, video, models that is not part of ViSP source code. This data set is available in Github (https://github.com/lagadic/visp-images) or as a release in a separate archive named visp-images-x.y.z.zip. This archive could be downloaded from https://visp.inria.fr/download page. Note that ViSP tutorials are not using ViSP data set.

We give hereafter the two ways to get this data set:

Get data set from github

Use git to get the data set latest version:

$ cd $VISP_WS
 git clone https://github.com/lagadic/visp-images.git

Once cloned, you need to set VISP_INPUT_IMAGE_PATH environment variable to help ViSP examples and tests to detect automatically the location of the requested data. In our case, this variable should be set to $VISP_WS%/visp-images. In a shell run:
```
$ echo "export VISP_INPUT_IMAGE_PATH=$VISP_WS/visp-images" >> ~/.bashrc
$ source ~/.bashrc
```

Test data set usage

From now, you can try to run ViSP examples and tests. For example you can run displayX example that should open a windows with Klimt painting image and some overlay drawings:

$ cd $VISP_WS/visp-build
$ ./example/device/display/displayX

A click to close the windows...

A click to display a cross...
Cross position: 201, 441

A click to exit the program...
Bye

Tips and tricks

How to take into account a newly installed 3rd party

Since all 3rd parties are optional you may have started to install only some of them. Imagine that you just installed a new third-party, or that you upgraded the version of this 3rd party. The next step is to go back to the build folder, configure ViSP with CMake to detect the newly installed third-party library and build again ViSP. This could be achieved with:

$ cd $VISP_WS/visp-build
$ cmake ../visp

Here you can check the content of the ViSP-third-party.txt file and see if the newly installed 3rd party is well detected (see Which are the 3rd party libraries that are used in ViSP ?).

Finally, you need to rebuild ViSP with:

$ make -j4

How to install ViSP

Installing ViSP is optional and not recommended, since ViSP could be used as a 3rd party without installation. If you still want to proceed with the installation run:

$ cd $VISP_WS/visp-build
$ sudo make install

Note

The default install location is set to /usr/local. This location could be changed modifying CMAKE_INSTALL_PREFIX var:

$ cd $VISP_WS/visp-build
$ cmake ../visp -DCMAKE_INSTALL_PREFIX=/usr
$ make -j4
$ sudo make install

If you proceed to ViSP installation in a system folder like /usr or /usr/local there is no need to Set VISP_DIR environment var that helps CMake to find ViSP libraries in an external project that uses ViSP as a 3rd party. If you rather install ViSP in a non "standard" folder, let say /my/install/folder, you have to set VISP_DIR to /my/install/folder/lib/cmake/visp that contains the VISPConfig.cmake file:

$ cd $VISP_WS/visp-build
$ cmake ../visp -DCMAKE_INSTALL_PREFIX=/my/install/folder
$ make -j4
$ sudo make install
$ echo "export VISP_DIR=/my/install/folder/lib/cmake/visp" >> ~/.bashrc
$ source ~/.bashrc

How to uninstall ViSP

After ViSP installation, you can remove installed material using:

$ cd $VISP_WS/visp-build
$ sudo make uninstall

How to build only ViSP libraries

If you want to build only ViSP modules libraries, nor the examples, tutorials and tests:

$ cd $VISP_WS/visp-build
$ make -j4 visp_modules

How to build a ViSP specific module

If you want to build a given module and all the dependencies:

$ cd $VISP_WS/visp-build
$ make -j4 visp_<module_name>

For example to build the model-based tracker module named mbt, run:

$ cd $VISP_WS/visp-build
$ make -j4 visp_mbt

Which are the targets that could be run with make ?

To know which are the target available with make:

$ make help | grep visp
... visp_tests
... visp_modules
... visp_examples
... visp_demos
... visp_tutorials
... visp_clipper
... visp_apriltag
... visp_core
... visp_gui
... visp_imgproc
... visp_io
... gen_visp_java_source
... visp_klt
... visp_me
... visp_sensor
... visp_ar
... visp_blob
... visp_robot
... visp_visual_features
... visp_vs
... visp_vision
... visp_detection
... visp_mbt
... visp_tt
... visp_tt_mi

Which are the 3rd party libraries that are used in ViSP ?

To see which are the optional 3rd parties that are found during the configuration stage and that will be used by ViSP during the build you can have a look to the text file named ViSP-third-party.txt and located in $VISP_WS/visp-build. We provide hereafter an example of a possible content of this file that contains also build info.

$ cat $VISP_WS/visp-build/ViSP-third-party.txt
