Constructing 3D cloud from set of similar 2D images

Hello MATLAB Community,

I am working on a project where I have to build a 3D reconstruction from a set of 2D images of an object taken by a moving vehicle. I want to know how to do it in MATLAB.

I will appreciate any help or direction in this regard.

Thanks all

Hi,

For the task of "constructing 3D cloud from a set of 2D images", you can refer to following workflow & resources:

1.Determine the intrinsic camera parameters (such as focal length, principal point, and distortion coefficients) and extrinsic camera parameters (position and orientation in 3D space) by a process called camera calibration.

For camera calibration, you can refer to

• https://www.mathworks.com/help/vision/ug/using-the-single-camera-calibrator-app.html
• https://www.mathworks.com/help/vision/ref/cameracalibrator-app.html

2.After you have calibrated the camera, please refer to this example of structure from motion from multiple views:

• https://www.mathworks.com/help/vision/ug/structure-from-motion-from-multiple-views.html .It mentions detailed steps as to how to reconstruct a 3-D scene from a sequence of 2-D views

Hope this helps you in your task.
