realtimebiomechanics / rtosim Goto Github PK

Good morning, I'm doing my master thesis in the development of a real-time system for biomechanical analysis in sports rehabilitation. After getting everything and install RTosim, what do I need to do? Thanks for the help

As discussed Claudio, it looks like in updated versions (not sure exactly when but at least from v1.7) Vicon has renamed the Client.h file to DataStreamClient.h

Hello,

I am currently working on a project that involves analyzing human arm motion using OpenSim. As a newcomer to OpenSim, I have recently come across the RTOSIM library, which offers real-time inverse kinematics and inverse dynamics capabilities. However, I am unsure about its compatibility with my specific project requirements.

In my project, I intend to use a camera and neural network for joint position estimation rather than a motion capture system. The neural network will be used to process the camera data and estimate the joint positions. I am interested in using RTOSIM to connect joints' positions from camera and neural network with OpenSim and perform real-time inverse kinematics and inverse dynamics calculations on the human arm model. My main question is whether RTOSIM can handle joint position data from a camera instead of using motion capture system data?

Bel lavoro!
Stavo provando a fare qualche simulazione e volevo capire meglio come settare i parametri dalla cmd.
Vorrei quindi sapere che tipo di valore accettano i seguenti comandi e se hanno un minimo e massimo (se sono numeri):

--fc
-a
-j
--push-frequency

While trying to build from sources with cmake, I got this error above. I couldn't see any references to this package (Concurrency) in rtosim docs. Which package is this? This was made in ubuntu 16.04.

CMake Error at CMakeLists.txt:37 (find_package):
By not providing "FindConcurrency.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"Concurrency", but CMake did not find one.

Could not find a package configuration file provided by "Concurrency" with
any of the following names:

ConcurrencyConfig.cmake
concurrency-config.cmake

Add the installation prefix of "Concurrency" to CMAKE_PREFIX_PATH or set
"Concurrency_DIR" to a directory containing one of the above files. If
"Concurrency" provides a separate development package or SDK, be sure it
has been installed.

If these exist, please let me know here and close the issue. Thanks

Hi,

would it be possible to stream sensor data via TCP/IP using e.g. LabStreamingLayer?

All the best,

I am trying to build rtosim in Visual Studio 2019, after installing and checking all dependencies. I am facing an error which says:

Error (active) E0289 no instance of constructor "rtosim::QueueData::QueueData [with T=rtosim::GeneralisedCoordinatesData]" matches the argument list argument types are: (std::optionalrtosim::GeneralisedCoordinatesFrame)

location is line 69 on the QueuesToInverseDynamics.cpp

I have also attached a snapshot of the detailed message. I am fairly new to rtosim, CMake and C++, so apologies in advance if this is not really an issue.

Kindly let me know if there is any other information needed from my end.

Thanks.

I'm trying to perform inverse kinematics by running the rtosim_ik_id_from_nexus.exe executable in the command line, with appropriate arguments.

The program starts, but when it accesses OpenSim API using the getCoordinateNamesFromModel() function (line 130 in https://github.com/RealTimeBiomechanics/rtosim/blob/master/src/mainInverseKinematicsInverseDynamicsFromNexus.cpp), I just get the message "Loaded model 3DGaitModel2392 from file gait2392_simbody.osim" in the command line and the program stops without going any further.
If I try to run this program again repeatedly, approximately every twentieth time I run the program it gets further to getMarkerNamesFromModel() (line 131), printing another "Loaded model 3DGaitModel2392 from file gait2392_simbody.osim" message in the command line and then nothing happens. I don't get an error message or anything, it just seems like the program stops after accessing OpenSim API (although it randomly makes it to the next step the API is accessed and then stops there).

I tried also with rtosim_ik_from_file.exe and I ran into the same issue where I get the message about the model having been loaded.

I'm not sure if this is an issue with the rtosim package, the OpenSim API or something on my end, but I would appreciate it if anyone could help me with this.

Does not compile due to conversion problem between steady_clock::time_point and ystem_clock::time_point

I have correctly compiled, build and installed rtosim.
Unfortunatly I am not able to run any of the examples. All the examples return
"Cannot create output directory", even if the output directory is created together with an empty output file.
I am exectuting the examples with admin privileges, in a not protected folder.

What am I doing wrong?

thanks

When I try to compile rtosim, I get this error:
CMake Error at examples/exampleViconNexus/CMakeLists.txt:18 (target_link_libraries):
Target "exampleViconNexus" links to:

rtb::rtosim

but the target was not found. Possible reasons include:

* There is a typo in the target name.
* A find_package call is missing for an IMPORTED target.
* An ALIAS target is missing.

If I don't add vicon, no problem in the generation.
Any help? Thanks

Hi!

After building the solution and attempting to run examples (of my own, because for some reason Vicon Virtual System 1.4.1 couldn't send the provided test data to Vicon Nexus) I get an error when I try to execute rtosim_ik_from_nexus.exe:

The error is in Finnish but translates to "The procedure entry point ?replace@ObjectGroup@OpenSim@@QEAAXPEBVObject@2@PEAV32@@z could not be located in the dynamic link library C:\Program Files (x86)\RTOSIM\bin\rtosim_ik_id_from_nexus.exe".

I get similar errors while trying to execute rtosim_id_from_file.exe, rtosim_ik_from_file.exe and rtosim_ik_id_from_file.exe, although the procedure entry points are slightly different and the dynamic link library refers to the executable I'm attempting to execute.

If you've run into similar issues, please let me know if and how you've solved them.

I didn't follow all of the versions given in the readme because they were outdated for many dependencies. Some of the versions I used were Simbody 3.7 without patching (because patching replaced some files which resulted in Visual Studio being unable to build the solution), Visual Studio 2019 and Vicon Datastream SDK 1.9.0.

Thanks in advance!

Hi,

Thank you for the nice work!

I was able to test rtosim ik and id on Arch Linux, however, I have encountered a random seg fault when executing rtosim_ik_id. It seems that there is some thread synchronization problem that can manifest randomly. Please see the attached file, which depicts one correct execution and 2 seg faults at different places.

I will look into the problem and if you have some clue where the problem may reside please let me know.

Dimitar

Nice work, the code fails to compile out of the box on VS 2019 because std::bind is not found due to missing #include I can open a PR if you agree.

Hi,
This is something I noticed while trying to run my own data with rtosim_ik_id_from_nexus.exe:
If you run the executable from the command line and provide paths with parameters and those paths include whitespaces, for example
rtosim_ik_id_from_nexus.exe --model "C:/Folder Name/myModel.osim"
then mainInverseKinematicsInverseDynamicsFromNexus.cpp fails to read the argument correctly because po.getParameter("--model"); will only return "C:/Folder", meaning that the whitespace in the name ends the string. This is not a major issue, but I thought I'd bring it up anyway. I haven't checked the other executables to see if they have a similar issue, but if they accept command line arguments similarly, they probably do.

Filter was not included as a dependency, please update the readme file to reflect latest dependencies. Thank you

Hi,

Could you tell me if this package is compatible with Opensim 4.0, please?
