Investigation of different sensor systems to classify plant and weed in organic farming applications

As part of a research project, a robot with the ability to distinguish root plants and weeds with various sensors will be developed. The given information is then being used to destroy the weeds automatically. This will help to minimize the use of pesticides, or even completely erase it, thus improving the environmental impact. The first step in this project is to evaluate various sensors to find out which sensor and which configuration can be used. Another wanted information is at what time of the plant growth period the plants can be distinguished. Too small plants give too little information to distinguish them. If the plants are too large, they overlap each other so much that the individual plants can no longer be separated good enough.
