3D-Mapper

• 3D-Mapper is a 3D plotting device made for short-range object detection powered by Atemega 2560.
• 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 library in Python, a 3D point cloud is generated from these Cartesian coordinates.
• A tetrahedral mesh is created by performing 3D Delaunay triangulation on the point cloud.
• Then the outer surface of this tetrahedral mesh is extracted to form a surface mesh.
