As the title states I looking for a way to (detect and then) determine a object within some range. The object will be forklift or "train" in the factory. Main goal is to provide some GUI from which it'll be possible to see where was the specific forklift or "train". There will be about 25 places in which I want to put Raspberry to detect those objects (forklifts and "trains"), determine what is the Id of this object it (e.g forklift with Id equals to 1, but I don't have to distinguish between forklift and "train", I care only about Id or something similiar which will be then send to some backend).
After some research on the Internet I have two possible solutions:
- using barcodes and reading their content (Id) using OpenCV,
- using RFID, but I couldn't find anything with larger distance with this technology
I know that this is not forum for "looking for complete solution with implementation", I only ask you for advices, technologies than can be used, feedback and maybe your experience with similiar problem. But code will be greatly appreciate if you done something similiar before.
