Topofusion in video
« on: November 22, 2007, 09:27:55 AM »
How can I use Topofusion?  I am working on a series of trail guides to introduce trails, show how to get there, were to go, what food, support, and hospitals are in the area. The video has a topo overlay with 'signs' to tell the new rider what to look for while riding. It also helps folks decide if that trail is at their level.

OK, this sample is 98MB. But this is 720x480 at almost DVD quality and you can make out the detail.

Full WMV - 98MB Open or right-click and save as

Youtube kills the resolution, but it is here now

I have a 3D capture too, but I have not added the audio to it yet, so it is not ready to show.

I am reworking it, so I may see about adding climbing analysis in spots to show the climb and descent better.

Hey, thanks for posting that.  Sure looks like a fun trail to ride, and you get a pretty good 'feel' for it in the video.

So the 3D model came from TF - how do you determine the bike position and orientation?  

Interested to hear/see more!

To synch the video, I compare the map that I created and exported with the features, waypoints, and directions.  I can then scan the video for turn by turn and figure out where I might be missing a point.  It can be a bit of detective work, but I can then get left/right/left in synch.

Here's something I did to highlight a local trail in a neighboring town:

Sorry, I thought I was posting this on the suggestions board but I followed a link and posted it here by mistake.

I was going to suggest the same thing.  I will check the links for more info.

Starting the video and TF at the same time will work as long as the video is continuous or at least long segments.  However, I use the helmet cam snow skiing with an hour long miniDV tape.  I generally get a full day of skiing on a tape because I shut off the camera when on the lifts or on groomed runs.  I don't want to be changing the tape during the day because the camera is buried in my backpack with wires running everywhere.  I have a similar problem windsurfing - the 2Gig SD card on the waterproof camera is only good for an hour of video.  At least it is easier to change but I have to come ashore to change it.

Looks like I will have to match the video and the TF track during editing.

Yep, it would be nice to sync up broken video segments as you describe.  I'm not sure there is a standard way to store time stamps for all the various video formats out there.

I'm no mpg or quicktime expert, though.  If there is such a format that is fairly widespread I could take a look at it.  It would be cool to pull images every, say 30 seconds, and display them on the map much like PhotoFusion.

Among other cool things you could do...
