# 3D-Mapper
* 3D-Mapper is a 3D plotting device made for short-range object detection powered by [ATmega 2560](https://github.com/LasithaAmarasinghe/3D-Mapper/blob/main/data%20sheets/ATMEGA2560.PDF).
* This is developed for the semester 4 project under EN 2160: Electronic Design Realization.
## Working Principle
* This device measures distances to objects using two Time-of-Flight (TOF) sensors, which are rotated by two stepper motors to cover the entire 3D environment.
* The distance values are saved in (r, theta, alpha) coordinates and then converted to (x, y, z) coordinates.
* Using the [PyVista](https://github.com/pyvista) library in Python, a 3D point cloud is generated from these cartesian coordinates.
* A tetrahedral mesh is created by performing [3D Delaunay triangulation](https://github.com/LasithaAmarasinghe/3D-Mapper/blob/main/3D%20Delaunay%20Triangulation.pdf) on the point cloud.
* Then the outer surface of this tetrahedral mesh is extracted to form a surface mesh.
## Why "3D-Mapper"?
* Precision in Short-Range Mapping
* Comprehensive Coverage
* Cost-Effective
* Scalability and Customization
* Versatility Across Industries
## Areas of Opportunity
* Emerging Technology Integration - Enhance capabilities with AI and machine learning.
