Exploring Camera Models

The new post delves into the specifics of various camera models, exploring the mathematical and geometric concepts used to represent how a camera captures the world. Especially, I focus on the distortion of various camera models. I introduce five camera models: Brown-Conrady distortion, Kannala-Brandt, Scaramuzza, Unified, and Double Sphere models, exploring their schematic representations, mathematical formulas, and parameter estimation methods. Also, you can control the parameters of the camera model and verify their role using the interactive demo.
