I have a project in which i need to get an object’s height and width through camera.That is if we open the camera and look the object through camera then object’s height and width will displayed in a text box.
can we do this or my idea is ambitious one ? Any help will be appreciated.
You could do that only if there is another metric available for you.
For example, user specified that size of particular object on the same picture is 1 meter. So by using simple geometry and math you could calculate other sizes. Without such information your problem could be resolved.
