Error building for TX2

[kyuhyong]

I followed everything in how to build documentation.

1. Installation of jetson inferrence was just fine
2. Have some issue with /usr/include/opencv2/gpu/gpu.hpp so I had to add following in /src/Base/cv.h using namespace std;
   just before #ifdef USE_CUDA
3. Still build error /home/nvidia/src/OpenKAI/src/Application/../Config/../SLAM/_ORB_SLAM2.h:13:20: fatal error: System.h: No such file or directory I simply cannot find where the System.h file located. How can I locate this file correctly? Thanks,

Kyu

[kyuhyong]

In an attempt to investigate whether the error was due to have not build ORB_SLAM2, I git downloaded the project on https://github.com/raulmur/ORB_SLAM2 And build was just fine. I found the System.h file inside the ORB_SLAM2 under /include however this file is not generic use as it requires followings too.

include

include

include<opencv2/core/core.hpp>

include "Tracking.h"

include "FrameDrawer.h"

include "MapDrawer.h"

include "Map.h"

include "LocalMapping.h"

include "LoopClosing.h"

include "KeyFrameDatabase.h"

include "ORBVocabulary.h"

include "Viewer.h"

This is very frustrating for me. Could you further explain what is needed for resolving this issue? Or what the System.h file supposed to be? Thanks,

Kyu

[yankailab]

Hi Kyu, the integration for orb slam is still under development, I will make a build option to separate orb Slam if you dont need it.

Meanwhile, I need a bit more time to fully support orb slam if you do need it.

[kyuhyong]

Hi. Thanks for your answer! I don't need to run SLAM at this moment and just to see how it performs with my drone setup. So there is a way to OFF building ORB_SLAM? I will check if I can do it in the cmakefile too and see if it works. Kyu

[kyuhyong]

I commented out #include "../SLAM/_ORB_SLAM2.h" in /Config/Module.h and now start to build and got following another error.

/home/nvidia/src/OpenKAI/src/Vision/_Flow.cpp:39:12: error: ‘createOptFlow_Farneback_GPU’ is not a member of ‘cv::superres’
  m_pFarn = superres::createOptFlow_Farneback_GPU();

I think this is due to incorrect OpenCV version I have on my tx2 Following is what I get about my opencv version.

$ dpkg -l | grep libopencv
ii  libopencv4tegra                             2.4.13-17-g5317135                            arm64        Tegra optimized Open Computer Vision Library

$ pkg-config --modversion opencv
3.2.0

Is OpenKai requires specific opencv version? Thanks,

Kyu

[GPrathap]

Yes, some of the modules are required OpenCV 3.x contribute modules as well. In order to build OpenCV 3.x, you can follow this[1]. Since it is required to build with contribute modules[2], there is a few command line options are to be added in build script which is mentioned in [1]. Commandline options can be found in [2].

Hello @kyuhyong and @kyuhyong, were you able to run openKAI on TX2? I managed to build (version without ORBSLAM) but I dont get the video from ZED in the openKAI window. What do I have to edit in the kiss file in order to get the ZED configured?

Thank you in advance!

[kyuhyong]

I was able to compile the code but now I get link error as following. [ 1%] Linking CXX executable OpenKAI /usr/bin/ld: warning: libopencv_core.so.2.4, needed by /usr/lib/gcc/aarch64-linux-gnu/5/../../../../lib/libopencv_gpu.so, may conflict with libopencv_core.so.3.2 /usr/bin/ld: CMakeFiles/OpenKAI.dir/src/Vision/_ZED.cpp.o: undefined reference to symbol '_ZN2cv3gpu6GpuMat6createEiii' //usr/lib/libopencv_core.so.2.4: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status CMakeFiles/OpenKAI.dir/build.make:2540: recipe for target 'OpenKAI' failed make[2]: *** [OpenKAI] Error 1 CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/OpenKAI.dir/all' failed make[1]: *** [CMakeFiles/OpenKAI.dir/all] Error 2 Makefile:83: recipe for target 'all' failed make: *** [all] Error 2 I think this error is due to ZED SDK is built with opencv 2.4 while I was trying to use opencv 3.2 I copied some library files into ZED's /lib but no success yet.

@SteveJos how did you solve this issue? Thanks,

[GPrathap]

Yeap still zed is being used OpenCV for Tegra 2.13.x version in tx2. Here is the trick which gets thing working.

1. reinstall OpenCV for Tegra. to do this hope you can locate libopencv4tegra-.....*.deb in your tk2 home folder.

   
   sudo dpkg -i libopencv4tegra-.....*.deb 
   sudo apt-get update
   sudo apt-get install libopencv4tegra libopencv4tegra-dev

More information: http://elinux.org/Jetson/Installing_OpenCV

2. open up go to build directory of OpenKAI, then type 
 `ccmake ..`

Note: if you don't have ccmake in your tx2 you can install it with `sudo apt-get install cmake-curses-gui`. if this is not working, ask from google how to install "CMake GUI for Linux". 

3. Set opencv location to build folder where opencv 3.2.x is installed. 
4.Then type c and g to generate cmake configuration files. 
4. Then to build OpenKAI, make -j3 in build directory of OpenKAI.
5. Then have a fun with OpenKAI.

`

[SteveJos]

@GPrathap Thank you for your solution. Unfortunately I dont see any option to change the path of opencv3.2. Furthermore did you try to compile and install OpenCV 3.x from source? Or does OpenKAI work just with the opencv4tegra stuff?

I get the following runtime error (after a succesful build):

` ZED (Init) >> Depth mode: Performance ZED (Init) >> Video mode: VGA@30

OpenCV Error: Gpu API call (invalid device function) in call, file /hdd/buildbot/slave_jetson_tx_3/35-O4T-L4T-R24/opencv/modules/gpu/include/opencv2/gpu/device/detail/transform_detail.hpp, line 320 terminate called after throwing an instance of 'cv::Exception' what(): /hdd/buildbot/slave_jetson_tx_3/35-O4T-L4T-R24/opencv/modules/gpu/include/opencv2/gpu/device/detail/transform_detail.hpp:320: error: (-217) invalid device function in function call

[SteveJos]

And if I run the latest code with apCopter_zed.kiss I still get a black window with FPS information etc. but no video recognition.

[GPrathap]

In here change the OpenCV include and lib directory into opencv 3.2.x build/lib and build/include directories.

You are getting this exception because of wrong liking is being happended. See this issue[https://github.com/opencv/opencv/issues/4849]. If you follow exactly what I suggest earlier you wont face any problem.

[SteveJos]

@GPrathap all right thank you for the hint disabling "USE_OPENCV4TEGRA" option! Then I can change the opencv directories. But as I understood one should compile with the opencv4tegra libs? Otherwise I end up with this compile error:

How did you exactly install/compile which version of opencv? It really gives me a headache :/

[GPrathap]

Please don't disable OPENCV4TEGRA. The error you are getting because of tracking API in OpenCV comes as an external module. You have to build OpenCV with this as well (https://github.com/opencv/opencv_contrib).

Please if you need any further instruction, please send an email or call via google hangout. I won't reply on the thread anymore.

[yankailab]

Compile with both OpenCV4Tegra and OpenCV3 on the same system is not a good idea it would mess up and make thing complicated.

So the problem seems to be that OpenKAI does not compile with stocked OpenCV4Tegra because it doesnt has contrib part.

I will update soon and make a build switch to separate the contrib needed part. OpenKAI should be compiled with OpenCV4Tegra out of box, it seems sometime ago I merged contrib part by mistake. Will do it soon.

[kyuhyong]

@yankailab Thank you for your reply. I look forward to have the update.

[yankailab]

@kyuhyong I updated CMakeList for TX2, it should work with stock OpenCV4Tegra 2.4.13 from JetPack3.1, please find here for detailed install process: http://www.openkai.xyz/tx1build.html

[kyuhyong]

@yankailab Thanks, I finally can build OpenKAI on TX2 with clean flashed Jetpack3.0. (I'm confused because the instruction still says its 3.0. Is Jetpack 3.1 correct?)

I still have problem running tho Followings are what I got.

Looks like I need to upgrade openCV? Maybe I have to start another thread.

[kyuhyong]

Sorry, I forgot to remove the onboard camera on TX2 but I still getting another error message.

hello, JetPack 3.1 for Jetson TX2 still have some issues in camera input and uart i/o etc., it is recommeded to use one earlier version JetPack 3.0 at the moment.

[kyuhyong]

@yankailab It's weird because I built OpenKAI on TX2 with Jetpack 3.0 and still not working. Below is what I got when tried to run.

[yankailab]

@kyuhyong , it looks you haven't installed OrbSlam2, if you don't need OrbSlam2, could you try to set "bInst":0 in "orbSlam2" in apCopter.kiss like below:

{ "name":"orbSlam2", "class":"_ORB_SLAM2", "FPS":30, "bInst":0, <-----------------------------------set it to 0 "Window":"apView", "_VisionBase":"brio", "width":640, "height":360, "bViewer":1, }

[yankailab]

@kyuhyong , another possible solution is to check the device ID of the camera instance setting in the .kiss file, e.g.

{ "name":"brio", "class":"Camera", "FPS":30, "bInst":1, "Window":"apView", "deviceID":0, <-- 0 means "/dev/video0", check if it exists in terminal by "ll /dev" command "width":1280, "height":720, "bFlip":0, "bGray":1, "calibFile":"/home/ubuntu/dev/workspace/OpenKAI/OpenKAI/data/calibration/brio_1280x720.xml", }

[SteveJos]

@kyuhyong @yankailab with the current release of OpenKAI I also get the error:

E1012 15:02:40.288002 28214 Startup.cpp:162] OpenKAI: Create instance failed: apView

It is independent of ZED or other cameras. ORB-SLAM and LSD are disabled. What could be the reason?

[yankailab]

@SteveJos , apView create instance will be failed if "bWindow":0 is set. Set "bWindow":1 to solve it. I add an output for this to make it clearer on launch.

[yankailab]

Added an install script for TX2 (tested on JetPack3.2) https://github.com/yankailab/OpenKAI/blob/master/sh/Install/OpenKAI_install_TX2.sh
