How to detect exact position in real world?
I am working on an agriculture app that helps farmers on the field. I want my app to detect exact real world location on the field.
Suppose that there is a farmer owns 100 decare garden with 1000 fruit trees. He is walking and checking the trees on the field. For example, he stopped at 45th fruit tree and looked at the app to see its information.
The main issue here is to detect real position on the field. How the app can detect farmer's position on the field without using GPS or Wi-fi? Using GPS is aimless, because the margin of error of a GPS is about 15 - 20m.
Any help would be appreciated.
There's no such tool that can return the exact irl position the device is located at. Either use GPS and find ways to compensate the error margin, put transmitters on each tree and make the device detect them, or use some sort of camera recognition algorithm that could recognize the tree.
