Zusammenfassung

Since experiments in agriculture are seasonally limited, development and evaluation of perception systems require special planning and preparations. In the research project AI-TEST-FIELD a test environment for the evaluation of sensor systems that offer the opportunity to generate precise and safe operations in a wide range of environmental conditions, was developed. The test environment combines a field-based test track, with which comparable sensor data is recorded automatically, and an evaluation pipeline, in which different sub-datasets can be evaluated by multiple algorithms for certain environmental conditions. In connection with different test parameters an evaluation procedure is proposed. Based on an analysis of triggering conditions for system insufficiency, test parameters and scenarios were defined. These test cases are processed in individual as well as continuous long-term experiments. Since tests on an abstract test environment are only one pillar for evaluation of a complete perception system a transfer onto real agricultural machines is done during fieldwork examples (e.g. mowing, tillage). The possibility to transfer outcomes from the test field environment to the real autonomous machines is one important aspect for the industry partners Maschinenfabrik Bernard Krone GmbH & Co. KG and LEMKEN GmbH & Co. KG within their development project Combined Powers.
