About KIRI Engine - 3D Scan & Edit

KIRI Engine 3D scanner app can reconstruct real-life objects into 3D models thanks to AI-based photogrammetry algorithms

All you need to get a photo-real 3D scan is to take at least 20 photos all around your object. KIRI Engine then processes the photos on our cloud servers (no need for a monster phone or PC) and outputs your 3D model

● QUEUING & PROCESSING ●

Our servers process your scans on a first-come-first-serve basis, usually takes 5-15 min. If many users are uploading projects simultaneously, you'll need to wait a little more, but never last more than a couple hours (in the worst rush hours)

Then, our server needs to process your 3D scans. It runs calculation on dozens/hundreds of photos, and needs a few minutes to do that :)

● BEFORE YOU SCAN ●

Photogrammetry works by identifying feature points in different photographs. This 3D scanning technology (in general) is challenged by certain scenarios:

‣ Low light scenes and dark objects are hard to be captured; high ISO noise or blurry photos caused by long exposure time will confuse photogrammetry algorithm, who won’t be able to generate a 3D geometry

‣ Transparent objects are impossible to capture, photogrammetry cannot comprehend or calculate refraction. Forget windows or anything with glass

‣ Shiny or reflective surfaces: photogrammetry doesn't know what a mirror is, or how to differentiate its reflection from the mirror’s actual surface. (E.g., If you take photos of a mirror, its reflection will look different depending on which angle you’re coming from.) Applies to anything that's too shiny, like metal, glossy finishes, etc

‣ Objects with low complexity are challenging too, photogrammetry needs as many features as possible to compare between images. Take a plain ball: the surface looks the same from every angle, so the photogrammetry algorithm won’t understand which side(s) it’s looking at

‣ Repetitive patterns, in the same essence as the previous point, are also hard to capture because it will possiblly leads to misalignment

‣ Things that are too thin, like plant leaves, spikes, and so on

So what DOES it work on?! Well, there are still lots of scannable objects! You can 3D scan shoes, figurines, furniture, wood, toys, sculptures, ... It works ultra well on things with lots of non-repetitive details (like wood, stone, textiles, and so on).

Trial & error is the key to photogrammetry's heart
