RebrickNet – Lego Part Detector

(I&#x27;m not a LEGO expert.)<p>It looks like LEGO provides 3D models for their components (e.g: via Bricklink [1]). Wouldn&#x27;t it be easier to generate the training data with a rendering pipeline of some sort that randomizes the brick position in a 3D scene with different lighting?<p>Of course you can still collect the user submissions for the test set<p>[1]: <a href="https:&#x2F;&#x2F;www.bricklink.com&#x2F;v3&#x2F;studio&#x2F;download.page" rel="nofollow">https:&#x2F;&#x2F;www.bricklink.com&#x2F;v3&#x2F;studio&#x2F;download.page</a>

I built a rudimentary brick sorting machine with the Lego color sensor many years ago, and I&#x27;ve seen some awesome brick sorting machines pop up over the years [1]. I started planning a sorting machine with a larger array of buckets in CAD but never got around to building it, hopefully the intrepid Lego fans over time will keep advancing the state of the art.<p>1. <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=04JkdHEX3Yk" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=04JkdHEX3Yk</a>

Another neat app if you have an iphone is Brickit which scans a large pile of your lego pieces and gives you build ideas.<p><a href="https:&#x2F;&#x2F;brickit.app&#x2F;" rel="nofollow">https:&#x2F;&#x2F;brickit.app&#x2F;</a>

Nice.<p>Reminds me of this: <a href="https:&#x2F;&#x2F;jacquesmattheij.com&#x2F;sorting-two-metric-tons-of-lego&#x2F;" rel="nofollow">https:&#x2F;&#x2F;jacquesmattheij.com&#x2F;sorting-two-metric-tons-of-lego&#x2F;</a>

I’ve tried different part detectors, and nothing has been as good as the Google Image search (download the Google App if you’re on an iPhone.) I’ve found it surprisingly good at identifying LEGO parts.

I&#x27;m curious how far away we are from a robot that can pick up LEGO pieces and stack them together according to the assembly-booklet.<p>And what kind of DL models would it use?

No mention of license on contributed data, or the model.

Neat, I happpened to rediscover and sort my childhood lego collection two weeks ago, and had good success for the &quot;no so common parts&quot; with the brickowl camera search (I don&#x27;t know what kind of engine is behind)

Does it use brickognize underneath?

RebrickNet is an abandoned project that supports only 300 parts. I recommend Brickognize [1], which recognizes all 85k Lego parts, minifigures, and sets.<p>Disclosure: I&#x27;m the creator.<p>[1] <a href="https:&#x2F;&#x2F;brickognize.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;brickognize.com&#x2F;</a>
