So in this case as the grid is set on the ground, it's measuring angles on the ground. The end points of the angles are considered to be on the grid and the angles calculated from that.

Even if you place the angles above the horizon, it will still calculate the coordinates as if they were on that calibrated plane. You can add a marker object and right click > "Display measure > Position" and then move it around to see this in action. (It will give weird values when it goes too much above the horizon that it can't project it on the ground anymore).

In this coordinate system these right angles are not right angles, you will need to set up the grid vertically.

Maybe the name perspective grid is a bit misleading, what it gives is a way to materialize the plane of motion.

Did you calibrate the coordinate system with the grid? You need to right click the grid, go to Calibrate and enter the real-world dimensions of the grid.
When in doubt you can display the coordinate system from menu Tools > Coordinate system.

The angle is measured by using the coordinates in the calibrated system.

Someone else posted something similar in the bug tracker but I still don't have any file to reproduce the problem.
Please send the KVA file so I can look into it.

Thanks! I could reproduce the issue and fix the crash.

The documentation is in the process of being updated and should be out soon-ish.

Very weird. What is your Windows version?
Is there maybe another image/video on your desktop that might cause it to freeze?
Just to confirm, by latest version you mean version 0.9.4?

This is not possible at the moment. The closest you can do is use the magnifier tool, this will show up in the exported video.

Hi all,

This is Kinovea 0.9.4. This should be the last beta release before the next version finally replaces the main stable download link.
Please report any critical issues as soon as possible.

Plugins for machine vision cameras:

  • Basler: Kinovea.Basler-0.9.4-x64.zip

  • Baumer: Kinovea.Baumer-0.9.4-x64.zip

  • Daheng Imaging: Kinovea.Daheng-0.9.4-x64.zip

  • IDS: Kinovea.IDS-0.9.4-x64.zip

-> Please check the download page instead for the links to the machine vision camera plugins.

Many thanks to everyone reporting bugs and helping with the testing!
This post highlights the most important updates, the changelog has a more exhaustive list.

   

1. Project-level updates

Machine vision plugins
The modules for machine vision cameras (Basler, IDS, etc.) have been split into separate plugins.
If you have one of these cameras please download the corresponding plugin, unzip it and check the readme.txt for installation instruction (basically copying the plugin folder to Plugins/Camera).

Translation
The translation of the program is now officially handled via Weblate, an awesome open source platform dedicated to translating software. You can help with the localization effort by registering on Weblate and start translating Kinovea right away. Thank you for your help!

Documentation
Most of the effort since last version was actually spent on updating the documentation but this is a gigantic task and will only be fully complete later, at which point we can finally release a normal non-beta version.

   

2. General usability improvements

Workspaces
Workspaces are now fully supported. Use the menu Options > Workspace > Save as default workspace to save the current screen arrangement and what video or camera is loaded in each screen. This screen arrangement and content will be read back when the program starts.

Combined with multi-instances this can be used to create and load complex setups where each instance is dedicated to a specific camera or replay observer.

Arm/disarm audio trigger
A small but important quality-of-life improvement, you can now disarm the audio trigger and also configure an "idle time" after each capture. This avoids spurious triggers while working on the computer between actual recordings.

Save vs Save as
The save command is now directly bound to saving the current KVA file so you no longer have to specify the target file every time.

Line calibration axis
When calibrating using a line, you can now specify if this line represents the horizontal or vertical axis of the coordinate system, (or if it should be ignored and the image axes used instead).

Folder observer
It's now easy to switch between normal video mode and folder observer by using the menu in the player infobar.

3. New Camera type: Baumer

Kinovea now supports a fourth type of machine vision cameras with the introduction of a module supporting Baumer cameras.

You can learn more about these cameras and check their specs at https://www.baumer.com

Many thanks to Baumer for providing cameras and technical support!

Oh, I didn't realize their latest cameras aren't compatible with their existing SDK. Well I was considering adding this new Peak SDK as well since it's supposed to support USB3 vision cameras from other vendors this would be a nice addition indeed. At the moment I'm focused on the documentation update though, and this will take a while more.

This should work out of the box in version 0.9.3 with the IDS SDK support.
IDS currently publish two different SDK, the Peak one and the classic one. The classic one is supported in Kinovea but only in the beta version, not in 0.8.15 which only supported DirectShow.
Can you try with 0.9.3?

If you want to work with the source code let me know because these machine vision plugins are in the process of being moved to a different place and will be distributed separately from now on.

The one issue I repeatedly have is that frequently, the cameras stop recording and just loop the last video recorded.

Can you clarify this? Is it that the video file is not created in the output directory or that the created file is not loaded in the replay observer?
Do you have the two observers monitoring the same folder and the capture screens saving to the same folder?
Can you send me a log to joan at kinovea dot org?

When this happens the only way to remedy is to shut down the camera windows and repoen them.

Using the pause button doesn't work? This disconnect and reconnect the camera.

Thanks

Hi,
This should already work but maybe there is a problem? If you have set a delay the resulting file should have its time origin set automatically. You should see the little red marker corresponding to the time origin and the beginning of the video should have negative time codes.

The videos are synchronize based on their respective time origin, in this case the audio trigger or manual start of recording, so if you open both videos side by side and use the slider in the joint controls at the bottom it should move in both videos in a synchronized manner.

If you haven't set a delay or don't use audio trigger you should still be able to synchronize them manually by setting a time origin in each video and using the joint controls.

If parts of this don't work as expected please describe what you are doing in more details. How many instances of Kinovea are running, what runs where, etc.

This should be fixed in the next version. In the meantime it should already work when using a replay folder observer. Otherwise you could work around it by going to Preferences > Capture > Recording and in the High speed cameras box, set Framerate replacement threshold to 100 fps (or 99 fps based on what you say) and Replacement framerate to 10 fps.

Yeah the current situation is not ideal… For me the priority should be to make the angle tool (and other trackable tools) user interface be as convenient/capable as the trajectory tool. The other big issue at the moment is that we can't easily change the sizes of the search and pattern boxes.

Maybe one way would be that when you click on "Start tracking" it creates 3 temporary trajectories objects that you can interact with as normal trajectories, and when you click "End tracking" it merges back the trajectories data into the angle points timelines.
