Hyperlapse

Sup!

Now this is totally unrelated to 3D printing but since we do a lot of timelapse videos I though I would share this link.

 

It would be nice to have a clean continuous moving print head that just add layers after layers instead of blurred or scattered print heads.

Interesting... think this will need some massive processing power...

Thanks for sharing but maybe better to put stuff like this in the gossip section.

Moved to gossip section.

Awesome thanks. It does make more sense there

Cool stuffs

I contacted one of the member of the research team and he was kind enough to reply and suggest to look at "motion denoising" instead. Hyperlapse is really focused on camera stabilization and would not really change much in this kind of timelapse.

I wonder if there are any implementation of this somewhere.

I love timelapses one very cool stuff with what you suggest can be done with a classic timelapse if you're printing in Spiralize mode, like i did here:

The timelapse here is quite slow (something like 12pics/sec). I'm shooting the pics with my RaspberryPi and Raspicam and i use a free software to make the video. I'll dig the internet to find something like what you showed would be cool to make the print look like it grows and have something less shaky

Yes that was one of the reference video I sent to the research team

Maybe the easiest way to do this is to shoot a regular video and to accelerate it.

In my case in the video it happens that the pics where taken every 20 seconds (i think) and that it was a bit longer than the multiplier time for a layer, let's say the layer took 4.1 seconds to complete i'd take a pic every 5 layers but the head looks a bit further.

 

[pm_dude 27]

yes that was how I did mine. Regular video and echo the frames.

 

The result is different... but become blurry on the print it self. I could have masked the echo with some work but my pc is getting a bit old and doesn't handle a lot of processing anymore :(

let's say the layer took 4.1 seconds to complete i'd take a pic every 5 layers but the head looks a bit further.

that works only if your layers are all the same length.

 

[DidierKlein 729]

Yes that's why it's probably doable only in spiralize mode with vases...

It's true that your video gets a bit blurry the result is different than a regular timelapse maybe it's too fast or indeed software tweaking could reduce the echo as you said
