Structure from Motion (SfM) in C++

Let’s explore Structure from Motion by figuring out the 3D layout of a small scene through a series of smartphone images. Choose nearby objects and take pictures with some overlap in what your camera captures. For accurate results, use a checkerboard to calibrate your camera — take a few shots from different angles. This calibration step provides vital info for the entire process.

Decoding PointNet: A Practical Guide to 3D Segmentation with Python and PyTorch

Get ready to explore the world of 3D segmentation as we take a journey through PointNet, a super cool way to understand 3D shapes. PointNet is like a smart tool for computers to look at 3D things, especially groups of points floating in space. It’s different from other methods because it works directly with these points, without forcing them into grids or pictures.
