Article
Full-text available
The leaf area is an important plant parameter for plant status and crop yield. In this paper, a low-cost time-of-flight camera, the Kinect v2, was mounted on a robotic platform to acquire 3-D data of maize plants in a greenhouse. The robotic platform drove through the maize rows and acquired 3-D images that were later registered and stitched. Three...

Full-text available
The goal of this work was to cluster maize plants perception points under six different growth stages in noisy 3D point clouds with known positions. The 3D point clouds were assembled with a 2D laser scanner mounted at the front of a mobile robot, fusing the data with the precise robot position, gained by a total station and an Inertial Measurement...
Article
Full-text available
Autonomous selective spraying could be a way for agriculture to reduce production costs, save resources, protect the environment and help to fulfill specific pesticide regulations. The objective of this paper was to investigate the use of a low-cost sonar sensor for autonomous selective spraying of single plants. For this, a belt driven autonomous...

To develop robust algorithms for agricultural navigation, different growth stages of the plants have to be considered. For fast validation and repeatable testing of algorithms, a dataset was recorded by a 4 wheeled robot, equipped with a frame of different sensors and was guided through maize rows. The robot position was simultaneously tracked by a...
Article
Full-text available
To overcome the limited transmission range of spatially separated nodes of a wireless sensor network (WSN), a small 4-wheel autonomous robot assembled the data from nodes distributed in a vineyard. First, the robot followed a predefined way-point route between the grapevine rows, in order to evaluate the sensor node locations by their received sign...
Conference Paper
Full-text available
A 2D laser scanner was mounted on the front of the small 4-wheel autonomous robot with differential steering, in an angle of 30 degrees pointing downwards. The machine was able to drive between maize rows and collect timestamped data simultaneously. The position of the vehicle was tracked by a highly precise total station. The data of the total sta...
Article
Full-text available
The authors wish to make the following corrections to Table 1 of the title paper [1]: the working environment of the PlantEye platform should be changed from "Greenhouse" to "Open field, Greenhouse" and the shadowing device of the Scanalyzer platform should be changed from "'√" to "x". [...].
Conference Paper
Full-text available
Selective spraying could be interesting for agriculture to reduce production costs, saving resources, protect the environment and even help to fulfill specific pesticides regulations of states. Autonomous robots can help to reduce labour costs with selective spraying and distribute the pesticides only where and when they are needed. The objective o...
Article
Full-text available
Efficiency increase of resources through automation of agriculture requires more information about the production process, as well as process and machinery status. Sensors are necessary for monitoring the status and condition of production by recognizing the surrounding structures such as objects, field structures, natural or artificial markers, an...
Conference Paper
Full-text available
Crop phenotyping is a prerequisite to enable robots doing agricultural tasks, evaluating crop status for farm management, and relating genotypes to phenotypes for crop breeding among others. Optical three dimensional (3-D) sensors have been preferred since they provide more information about the complex plant architecture. The improvement of time-o...
Article
Full-text available
3D crop reconstruction with a high temporal resolution and by the use of non-destructive measuring technologies can support the automation of plant phenotyping processes. Thereby, the availability of such 3D data can give valuable information about the plant development and the interaction of the plant genotype with the environment. This article pr...
