Virtual camera is created only using opencv and numpy. It simulates a camera where we can control all its parameters, intrinsic and extrinsic to get a better understanding how each component in the camera projection matrix affects the final image of the object captured by the camera.

This is a fun project I created to motivate computer vision enthusiasts and to highlight the importance of understanding fundamental concepts related to image formation in a camera.

Project (transform) point coordinates from 3D to 2D and unproject them back.

Python implementation for Zhang's camera calibration.

What is a camera calibration, why is it necessary, and how do we compute it?

About This project represents the use of Z-Buffer for rendering of basic 3D objects.

PixoCube is a digital version of photo cubes that people usually gift others. It is basically a 3D cube with different images consisting of different sides of the cube. The interesting part of this project is I used concepts of camera projection and only opencv functions to render the cube. Moreover the camera view point is rendered such that it…

Camera calibration using OpenCV

This project represents the use of Z-Buffer for rendering of basic 3D objects.

This is a simulator of a novel cross-reality environment that seamlessly integrates a monoscopic 2D surface with a stereoscopic 3D space to jointly host spatial data visualizations.
