Hi I am trying to take world coordinate from image coordinates i mean i want to take real point of object for example i am using web camera so can i take real point of object help me please
Augmented Reality applications (which I think is what you’re describing) generally rely on the use of special “markers” attached to objects so that an algorithm can be used to efficiently determine their position and orientation. There are also libraries designed for specific sorts of markerless image recognition - e.g. Face recognition. Both of these types of application exist for Unity - so, depending on what type of “object” you had in mind, try searching the asset store for examples.
