AI-Powered 3D Model Reconstruction from 2D Sketches for Basic Solids
Develop an artificial intelligence solution to reconstruct 3D shapes from 2D freehand sketches, focusing on transforming irregular strokes into geometric models like cuboids through a systematic process. Explore related works in 3D model retrieval methods using hand-drawn sketches and address the gap in data availability for matching freehand sketches with 2D polygons.

3D Model Reconstruction 3D Model Reconstruction From 2D Sketch From 2D Sketch Name:- Jesuthasu Samson Supervisor:- Mr. S. Suthakar Reg No:- 2006/CSC/006
DEFINITION DEFINITION Problem Problem:- 3D shape reconstruction from 2D freehand sketch for basic solids Objective Objective:- Develop an artificial intelligence able to emulate cognitive functions regarding spatial imagination and other capabilities Input Input: a hand-made sketch (2D) Output Output: a cuboid (3D) Despite the imprecision of a freehand sketch, a person could also say that the strokes represent a particular solid (Eg: cuboid), but for a machine, it is a step by step process
STEPS STEPS Input Input: a hand-made sketch (2D) Output Output: a cuboid (3D) 1. Transform the irregular strokes into string lines 2. Extract the required measurements 3. Obtain the corresponding conceptual geometry after a heuristic interpretation process
RELATED WORKS RELATED WORKS A 3D Model Retrieval Method Using 2D Freehand Sketches Retrieve desired 3D models by measuring the similarity between a user s freehand sketches and 2D orthogonal views generated from 3D models 3D Shape Reconstruction from Sketches via Multi-view Convolutional Networks output a dense point cloud representing a 3D reconstruction, convert into a polygon mesh, using encoder-decoder network the multi-view maps are then consolidated into a 3D point cloud 3D Model Retrieval Based on Hand Drawn Sketches Using LDA Model generate 2D views of 3D models, extract low level features from sketch and 2D views and encode them as visual words, use LDA method to achieve topics distribution
GAP GAP Only few data related to the 2D polygon are available to match the free hand sketches Here I will introduce a mathematical method to construct 2D sketches into 3D models without the middle conversion which is to convert free hand sketches to 2D polygon by matching similarity
