Collaborative project: Smart vision sensor for site-specific herbicide spraying in real-time operation (H-Sensor) – Subproject 1
Project
Project code: 2815302207
Contract period: 01.12.2007
- 30.11.2010
Budget: 170,901 Euro
Purpose of research: Experimental development
In agricultural practice weeds appear heterogeneously in arable crops. Therefore the application of herbicides is necessary only on a small part of the total area. The herbicides are applied site-specifically corresponding to the threshold principle. The technology has to differentiate between weeds and cultivated plants as well as between different weed species. The targets of this joint research project were the development of a prototype, tests of a smart vision sensor for site specific herbicide spraying in real time operation and evaluation of selected application scenarios. Such a system consists of several smart vision cameras with integrated image processing and object recognition as well as an operation terminal. The cameras are mounted with brackets at the spraying boom. The cameras continuously record images of cultivated plants while the sprayer is driving over the field. All visible plants respectively their aerial parts are evaluated and assigned to classifiers. Different spraying decisions for different crop and application cases are stored in the terminal. In real-time operation these spraying decisions decide which application and which application rate is needed. All separate system components as well as the complete system have been already tested successfully in field trials. The H-sensor recognized all weed-infested partial areas. Approximately 40 % of herbicides could be saved. This project showed clearly that the realization of a practical real- time operation system is definitely possible. The complete system will be enhanced with large scale technological innovations (for example a more robust camera system) and reduction of the production costs in the follow up project (H-Sensor 2).
