Sometimes weird values from API call

Hi folks, sometimes, sporadically but (talking about several ten seconds to minutes), I get weird values from a remote API call. Sometimes it's a NaN, sometimes values that are completely wrong. Is there a known issue regarding reliability of remote API calls? This is also expressing in UI events th...

Re: Distortion parameters from vision sensor?

I somehow figured it out myself. The easiest way to get the required parameters is by using camera calibration tools provided by the corresponding ROS package and creating an appropriate checker board in V-REP by hand (I used a texture made with The Gimp).

Re: Crash in 3.0.5b 64bit (Linux) when starting simulation

Yeah, that's absolutely possible. I have a dialog box in one of my scripts.

The crash has only occured on one of my three machines, yet: the least important one, luckily. So, as far as I'm concerned, there's no need to dig deeper.

Thanks anyway

Crash in 3.0.5b 64bit (Linux) when starting simulation

Hi folks, I'm running into a problem here after updating my V-REP installation to 3.0.5b. I can load my old scene (created with 3.0.4) but when I want to start the simulation, V-REP just crashes with a segfault: Simulator launched. Plugin 'Dynamics': loading... Plugin 'Dynamics': load succeeded. Plu...

Re: Installing V-Rep on Ubuntu 13.10 x64

I've solved this issue by removing all libQt* files from the V-REP directory. But I've got Kubuntu 13.04. Hope that helps anyway. In case your internet connection is too slow for a new download of V-REP (if something went wrong) don't forget to make a backup of anything you want to delete!

Distortion parameters from vision sensor?

Hey again,

I'm looking for a way to fill in the sensor_msgs/CameraInfo fields from a vision sensor. What's the best way to get the values for distortion parameters and everything ROS needs in order to work with it?

And thanks again!

Cheers,
Hendrik

Working on a C# API wrapper

Hi folks, a while ago I started working on a C#/.NET wrapper DLL that can be used for writing remote API clients in any of the many Microsoft .NET languages. For this purpose I've opened a repository on GitHub (https://github.com/SeveQ/remoteApiNETWrapper). I'm adding functions/methods whenever I ne...

Re: c#

I'm currently writing a .NET wrapper DLL for the remoteApi.dll. It's pretty easy, once you've figured out how. Just a diligent but routine piece of work... Here's how you can provide a remoteApi.dll function to C#: [DllImport("remoteApi.dll")] public static extern int simxStart(string ip, ...
