If you prefer to use a DSLR for the job, this Bluetooth intervalometer might help.

But has made all the sources available, so feel free to build on his work. Sadly, the batteries only last for a couple of days, so those long six-month exposures aren’t possible yet. A custom hat powers up the Pi every few minutes, which boots up and takes the two pictures. To automate the process, used a Raspberry Pi and a Pi-Cam fitted in a weatherproof 3D-printed box. Add the two resulting images and you’ve got a solargraph. All the foreground images are averaged, while the stopped-down sun images are overlaid upon each other, producing the track of the sun across the sky. His solution was to take a pair of photos at each timepoint - one correctly exposed to capture the scene, and one stopped way down to just capture the position of the sun as a pinprick of light. He found that this just averaged out the sun from the final image.

searched for a way to make a digital camera perform like a film-based solargraphic camera, first thinking to take a series of images during the day and average them together. Not at all, thanks to this digital solargraphy setup. But what if you don’t want to use film? Is solargraphy out of reach to the digital photographers of the world? Have you ever heard of solargraphy? The name tells you much of what you need to know, but the images created with a homemade pinhole camera and a piece of photographic film can be visually arresting, showing as they do the cumulative tracks of the sun’s daily journey across the sky over many months.

Solargraph from a one-year exposure on film. Is there a resin printer in your future? If so, you might want to look over ’s guide to the pros and cons of SLA compared to FDM printers.Ĭontinue reading “Silky Smooth Resin Printer Timelapses Thanks To Machine Vision” → Posted in 3d Printer hacks Tagged Circle-Hough, Elegoo, intervalometer, machine vision, MSLA, opencv, RIFE, sla, time-lapse

Alex kindly provides his code if you want to give this a whack it’s almost worth buying a resin printer just to try. The details of that technique alone were worth the price of admission, and the results are spectacular.

To smooth things out further, also used frame interpolation to fill in the gaps where the build platform appears to jump between frames using real-time intermediate flow estimation, or RIFE. A Python program then sorts the frames, so it looks like the resin print is being pulled out of the vat in one smooth pull. The LED acts as a fiducial that OpenCV can easily find in each frame, one that indicates the Z-axis position of the stage when the photo was taken. The advantage of his method is that it’ll work with any camera and requires no hardware other than a little LED throwie attached to the build platform of the printer. Or are they? found a way to make gorgeous time-lapse videos of resin printers that have to be seen to be believed.

That’s easy enough to do on FDM printers, but resin printers are another thing altogether. Trouble is they tend to look choppy and unpleasant unless the exposures are synchronized to the motion of the gantry. The fascination of watching a 3D printer go through its paces does tend to wear off after you spent a few hours doing it, in which case those cool time-lapse videos come in handy.
