So, to sum up options… Don't know what will end up in the software but if you have other ideas they are welcome:

- Having a simple visual clue of the speed, without the exact measurements. (ex: circles at each frames (closer=slower), circles with varying size, color coding of the speed, changes in width of the track (thiner=faster), etc.

- Having a small dynamic label with the total distance from begining to current image, and/or current speed, the label would only be visible for the current frame.
Also being able to view the last segment distance at any time.

- Being able to choose among various informations to show for key images. Key image title, total distance from the begining, distance from last point, speed, others ?


Ideally the number of options available would fit in a single configuration page without too much clutter.
(This could be done by identifying group of options that go together and make them available as bundles instead of giving 100% control over the display, wich can cause confusion if not necessary.)

Also, some more thoughts regarding coordinate axis :
- Having a new menu "Coordinate Axis" under "Image" : By defaut it would add a coordinate axis directly on the image, plus an horizontal and a vertical ruler on the sides.
Plus a way to display a complete overlaying grid based on the current coordinate system.
- Being able to change the coordinate axis by direct manipulation somehow. (and dropping the current extra window of the trajectory tool).
- Having the mouse pointer coordinates (in this system) displayed in the status bar.

For speed measurements, the units should be configurable… The distance calibration might be in centimeters or in feet, it may still make more sense to have a speed in Kilometers per hour or in meters per seconds (or even maybe in Knots, or other speed specific unit).
That should probably end up in the general preferences…

Hi, yes it would be a great feature to have (although without a real 3D context, the actual usefulness have to be assessed).

As you wrote this should be an extension of the trajectory tool, so right now there are things more critical to it. (improving the automatic tracking, tracking multiple points.)
When tracking multiple points will be in place having a wire frame buddy as the tracked point collection should be straightforward.

It's already on the suggestion list, but there are a significant ammount of things to fix/improve first.

Hi everyone and happy 2010 smile

Sorry for the lack of comments lately, internet is scarce (actually for the past few days I was in a place where electricity wasn't delivered smile)

Yes please send back the file to joan at kinovea dot org.

Concerning seal/calibrate measure vs measured dimension, I think the menu should correspond to the action that the user will be able to do when he clicks the menu, so I would rather keep it as a verb...

For the manual, I thinks it's best to wait a bit because it might change significantly and it will be harder to merge afterwards.

Thank you all for the efforts !

Hi, thanks for the message.

1 and 2 sounds like you are trying to follow point(s), is this right ? In this case I guess the best thing would be to implement speed calculations within the trajectory tool (?).
Currently one may do this by exporting the trajectory data to a spreadsheet application and make the computations there.

Point 3 sounds like an interesting challenge smile

4 and 5. Yes, this also came up in feedback for trajectory tool and was implemented recently (but only for trajectory for now).
I guess when the data export is available for points, lines and angles, the coordinate system setup will have to be moved in a more accessible location…

I'll consolidate all this in the suggestion list when time permits.
"Human model tool" to adjust on the actual person will probably only be implemented during a later phase, with other "complex" drawings though.

Hi,
Thanks a lot for the feedback and the example video.

About coordinates, currently you can export them to spreadsheet documents. (A dialog window that would sum them up was considered but this is currently on hold.)

There are two things you may want to do before exporting,
1. Set the scale; place a line on a object of known length, then right click + "Seal measure" and input the length.
2. Set the coordinates origin; by default the origin point {0;0} is equal to the first point of the trajectory.
To set it to another point, right click on the trajectory + configure + "Coordinates system origin".

This will not really compute the distance between two points, but you may do that, and more, in the spreadsheet app.

Let me know if this work for you or how it could be made more straightforward etc…

Hi,
That is strange. I just tried and it worked for me.
What is the version of OpenOffice or Excel that you are using ? I could only test with Office 2003 and OpenOffice 3.0 and 3.1.

Also, you can try to open the .xml (Excel) file in notepad and try to see if the coords are there.
The data will look mangled, but try to look for something like :
<Cell ss:StyleID="s24"><Data ss:Type="Number">-38.00</Data></Cell>

(bold is a coordinate)
If they are all zero here, then the issue is somewhere else…

Hi,

No codec should be needed, they won't be used anyway.
If the file is small enough, you could open a bug in the bug tracker and upload it along the bug report.

Also, to start the analysis, you (or other users if you upload the file) can try to read the file in VLC Media Player and/or MPlayer.
It helps figure out if the issue is in the FFMpeg library (shared among these softwares and Kinovea) or somewhere else.

Thank you

Hi, thanks for the feedback.

As you noted the stopwatch is currently a simple one. There has been suggestions to make it more powerful with the ability to record multiple times with the same stopwatch, but that would complexify the current tool too much I think. (Because such a basic tool should be as simple as possible…)

I guess changing the options to "start", "pause", "continue", may be considered… would that be explicit enough for every use ?

I think it would be good to have input from others users on this. Should the simple stopwatch stay as simple as it can be and a more powerful stopwatch made into a new tool, or should the enhanced stopwatch become the basic tool ?

Hi,

I'm not sure it's what you are looking for, but you can get the coordinates of the points of a trajectory by using the export to spreadsheet function, from the file menu.
Currently there is no way to get them directly from within the software, you have to export them.

I would also ideally like to be able to programatically plot points on images or on overlays of the images.

You could try to programmatically generate a .kva file and then import it. ("Load Key Images data…" menu)
.kva is the XML description of the key images and drawings. There is currently no shema or DTD, but you could set a few points and export them to see how the format works.

I am interested in knowing more about your workflow and what you are doing, picked my curiosity smile

Some have reported trouble with the wording "Seal measure". I agree it's not very clear… neutral

Please consider this as "Calibrate measure...". If you have an equivalent.
It is used to set the real world size of a line. (through right click)

Thanks !

Bonjour,
Merci pour ce retour.
Je vais ajouter ces suggestions à la liste.

Pour l'ouverture de suites d'images en tant que vidéo, je pense que cela pourrait intéresser potentiellement d'autres personnes en dehors du milieu de l'animation, mais il faut que je vois comment l'organiser au niveau de l'ouverture des fichiers et comment l'intégrer derrière. Ce ne sera pas pour tout de suite mais je vais y réfléchir smile
