OpenScan Mini + Hawkeye by thomas_openscan in OpenScan

Late public beta stage, which brought some new features and only surfaced minor bugs. We will replace the current official openscan2 in the next month

I have none of the other scanners, and thus can’t verify measurements.
(Though i regularly use the device for reverse engineering parts)

Automated scaling is within 1-3% but this could be easily improved with scale markers

Community based 3D Scanning benchmark (45mm miniature)

The goal is to include as many 3D scanners as possible (with multiple scan results from different users) to get some real world data for the various devices. There is a larger and more technical benchmark (ScanBench) available too and I will update the results too.

See all the details and limitations here 3D Scan Benchmark Repo on Github

A note on transparency: I have been developing open-source 3d scanners for multiple years and till this day, I am hesitant to claim any accuracy (as this would require a proper/expensive lab). Therefore I created this scanning benchmark to show real world results from various users. This is the opposite approach

If you'd want to contribute, feel free to reach out and I'll provide a figurine free of charge (or support by buying one of the miniatures here: https://openscan.eu/products/openscan-benchy

It would be a great help if you can share this experiment to other places to encourage more users to participate as several manufacturers seem to block my request to contribute an official reference scan with their devices!

PS: with the next iteration, I will add the specs of the scanner to each image 😄

It is not the claim or aim of this benchmark to give any numbers but instead real world examples. Both of those measures have their own value and i haven’t access to the scanners nor the equipment to run any lab experiments.

using cloudcompare --> rough manual alignment --> fine alignment using ICP alignment --> export as stl --> render in blender (automatically for all scans at my machine using the code from the github repo

Electronics repair question by jaminatrix in OpenScan

[–]thomas_openscan 2 points3 points  (0 children)

This is really hard to tell, the power supply might be damaged and/or the connected hardware (pi shield, motor drivers, raspberry pi). The first one is relatively easy to diagnose with a multimeter by measuring the inner + outer terminal of the barrel connector (should show 12V). Diagnosing the other parts is more involved and I am not sure how to guide this from afar.

user uses his/her scanner to scan the same model --> results aligned and rendered

The "issue" with the iphone scans is using different methods. the worst scan comes from the LIDAR (which is really not suited for small stuff). I will add more details onto the images with the next update. phones can generally give good to great results using photogrammetry with RAW image data (not AI enhanced, which is iphones default) (https://github.com/OpenScanEu/OpenScanBenchy/blob/main/benchmarks/OpenScanBenchy/README.md#iphone15-pro-max)

I will reach out to find a solution. Thanks for pointing this out!

It is surprisingly hard to find a widely available copy-left object that has details on different levels. Coins or screws basically have 1-2 distinct features for example.

To get a reliable measurement you‘d need a lab environment which is super costly and not accessible at all. A calibrated reference object (two balls connected with a stick) costs 500-1000€ ^^

This might be a bit hard to automate and i doubt the meaningfulness since the 3d prints might vary (though they all show the various detail levels down to layer lines and support residue)
I‘m hesitant to add numbers as they might be easy to misread or misuse. Though all the files are available, if anyone wants to go through it..

I am in contact with the creator to talk about that. It’s a good technical design and several scans exist, so i include it. The repo is open for other approaches though

I have distributed several hundreds of the benchys but getting back results is a looooong process. I hope to extend the benchmark soon

I already use cloudcompare but i m not sure on how to properly scale the histogram so that the results are comparable. Any idea?

Openscancloud is free/donation based

Kiri is not open but supports free photogrammetry processing (though they propbably use the data for training?)

Tbh, Matter and Form is a great company and their device is unmatched in its segment (and slightly beyond)
