Hi Mohit,

The function pointsToWorld is under a class named cameraParameters. You can refer to the code provided in the class to understand the mathematics involved behind converting co-ordinates in an image to world co-ordinates. You can execute the following command to see the class definition --

>> edit cameraParameters.m

Additionally, the function can also be accessed from MATLAB Command Prompt by executing the following command -

>> edit cameraParameters.pointsToWorld

Regards.

Thank You! for your answer, I saw this code and I was thinking that if there is any published paper on this method because in this code nowhere calculation/formulas are shown. Also, so many unknown functions (to me) are used in this script.

Since R2020a, you can do

>> edit pointsToWorld
