Accelerating and improving breeding towards more efficient crops and varieties is key for increasing yield and improving the resilience of plants. For plant breeders, it is important to observe and document phenotypic traits describing the appearance of plants in the field to evaluate the quality and success of the breeding process. With Pheno-Inspect, we aim at offering growers and farmers novel software solutions for automated high-throughput phenotyping in the fields. For remote sensing, we rely on small and lightweight aerial platforms, which enable a flexible, large-area and time-efficient survey of fields and plot experiments. With our software toolchain, we provide breeders and farmers with a tool to gain precise knowledge of the crop and individual plants. We automatically detect phenotypic traits of crop plants, the species of plants, and weeds in the field and derive site- or plot-specific statistics. Our approach relies on state-of-the-art machine learning methods optimized for the agricultural domain to semantically interpret the captured image data and to extract the desired parameters about the plants. The learning procedures developed by us use expert knowledge inserted by the user to adapt efficiently and thus deliver the desired results quickly and effectively with regard to individual problems and local characteristics of the environment.

RegisTer targets the use of artificial intelligence and optical sensors in the variety description of the Federal Plant Variety Office in the examination for distinctiveness, uniformity, and stability and the value for cultivation within the scope of the variety approval for sugar beets.
Sugar beet is a common crop in Germany and represents an important economic factor for rural areas. Modern varieties must have diverse characteristics such as disease and stress tolerance and high yield potential. These characteristics must be recognized quickly and reliably in the breeding and approval process. Furthermore, each variety must be clearly described and be distinguishable. The goal of the interdisciplinary collaborative project RegisTer is to develop automated routines for the characterization and evaluation of sugar beet varieties based on the geometric and optical/reflective properties of the plants, which are measured using ultra-light flying drones. Drones, equipped with high-resolution RGB and multi-spectral cameras and 3D sensors, are used to measure test fields. A millimeter-precise data set is the basis to automatically analyze the plant parameters with state-of-the-art image processing based on machine learning down to the individual plant level. The aim is to automatically extract (new) plant characteristics and their valuable properties for variety description and variety evaluation. The aim of this project is to achieve automation, standardization, and improvement of the assessment process for the register and value tests at the Federal Plant Variety Office and performance tests in the plant breeding industry, which is characterized by small and medium-sized enterprises.
The RegisTer project is technologically based on recording experimental plots and individual plants using drones and terrestrial laser scanning. The drone, equipped with high-resolution RGB and multi-spectral cameras, systematically records test plots at various locations within Germany and observes the plants with the required resolution in the millimeter range. These data form the basis for the investigation of the phenotype. In addition to the 3D data from drone images’ processing, we also collect high-precision 3D data utilizing terrestrial laser scanning, which we use to extract the leaf apparatus’ geometric parameters and for quality control of the 3D data from the drone images.
For the extraction of the register and value characteristics, we develop the most modern image processing with machine learning methods, which aim to recognize and analyze single plants, but at the same time also for the evaluation on the level of the plots. In addition to the automatic recognition of already existing traits, we also examine the data of new, previously unused factors for register inspection. For this purpose, we pursue the working hypothesis that the data contain variety-specific patterns suitable for distinctness and identification of sugar beet varieties. We link the data over different points in time and derive dynamic characteristics. We investigate these parameters to develop new traits for variety description and use the temporal correlation in the data to improve the self-learning algorithms further.

Hercide-Free Weed Control
2021/09 – 2023/12, DBU
Where weeds grow, we spray. Chemical weed control is still common on about 90% of all agriculturally used land in Germany. Numerous studies prove the connection between pesticide use and the significant decline in biodiversity.
In comparison, organic farming leads to a significant increase in biodiversity and thus makes an essential contribution to a functioning ecosystem. Non-chemical weed control is in many cases more laborious and expensive, as manual weeding is still indispensable here, significantly when growing sown, slow-growing crops such as carrots and other root crops.
The start-up tiefgrün precision weeding aims to bring an ecological method to practical maturity based on self-learning plant recognition, which can be economically competitive with herbicide application in the long term. Pheno-Inspect GmbH is responsible for developing the necessary image-based classification of plants and weeds.
The project goal is a demonstration machine for automated weed control in organic carrot cultivation: the KelvinR370. The machine is designed to detect plants based on cameras, distinguish crops from weeds with a high degree of certainty, and regulate the latter with pinpoint accuracy. The project comprises the development, construction, and field testing of a prototype and, building on this, the implementation and practical evaluation of the KelvinR370 demonstration machine by tiefgrün. For use in sensitive crop stands, tiefgrün is developing a precise, pinpoint weed control system, integrating it into the device, and investigating its effect under practical conditions. At the same time, Pheno-Inspect is developing an image processing pipeline tailored to the system for robust classification of carrots and weeds and simultaneous detection of their root points – with maximum reliability under different field conditions.
