3D Python Tutorial: Building 3D Models from 2D Images (Photo or AI) with 5 Libraries

This tutorial shows how to create a 3D model (point cloud) from a single image with 5 Python Libraries. The input is a 2D image (from AI or your camera), and we generate a 3D Model. I cover everything from setting up your environment to generating your 3D Point Cloud Model (going through Monocular Depth Estimation).
I go through several linear phases that follow the different chapters.

Thank you so much for the tutorial! It's super clear and helpful!

[@FlorentPoux]

You're very welcome!

[@user-fy2hz2og3b]

So clever!

[@FlorentPoux]

So many creative ways it can be used!

Hi Florent! I'm launching a startup that offers 3D menus for restaurants, cafes, and more. Currently, I'm researching how to create 3D models from images of dishes taken from various angles. Could you recommend any tools for this process? It's essential to maintain accurate colors and ensure high-quality models so that clients can navigate and examine details with zoom capabilities, etc. Thank you for your help, and I appreciate the valuable content you provide!

[@FlorentPoux]

Sounds great! So, I think you could turn yourself towards turntables and automate the scanning process with a lightbox to control lighting. then, you can use 3D Gaussian Splatting for the visual quality of the rendering you would get from it.

Sir , how we convert 3d images to floor plan

[@HarryStylesFanSansy]

lmao got the same internship assignment???

[@adityaranjan5078]

@@HarryStylesFanSansy Have you any idea about this?

[@FlorentPoux]

A Very good idea indeed! And this is a vast topic, I will heavily dive on it next month, but basically, decompose the process in (1) classification, and (2) vectorization (regression)

[@MohammadKazemi-yd1jl]

where can I access the code?

[@FlorentPoux]

in the comment there is a drive folder with code
