New Robotic System Accurately Assessing Corn Plant Health Through Leaf Angle Measurements
Introduction:
Introducing AngleNet, a groundbreaking robotic system developed by North Carolina State University and Iowa State University. This innovative system revolutionizes the measurement of corn plant performance by automating the process of checking the angle of the plant’s leaves relative to its stem. Using the PhenoBot 3.0 agricultural robot equipped with special machine-learning-based software and PhenoStereo camera modules, AngleNet captures stereoscopic side-view photographs of the leaves and generates three-dimensional models to calculate leaf angles accurately. Furthermore, this technology provides crucial information about the height of the leaves from the ground. With the potential to expedite plant breeding research and improve crop yield, AngleNet represents a significant advancement in the field of agricultural robotics.

Robotic System Measures Corn Plant Photosynthesis Effortlessly
A groundbreaking robotic system has been developed by researchers from North Carolina State University and Iowa State University to assess the photosynthesis activity of a corn plant. This innovative system, called AngleNet, combines a state-of-the-art agricultural robot known as PhenoBot 3.0 with advanced machine learning software, enabling rapid and accurate measurements.
The AngleNet system comprises four PhenoStereo camera modules mounted on the robot. Each module consists of two cameras and a set of strobe lights, arranged one above the other with spaces in between. As the robot moves along rows of corn plants, the cameras capture stereoscopic side-view photographs of the leaves at various heights. The software then processes these images to create precise three-dimensional models of the leaves, allowing for the calculation of leaf angles in relation to the stem. Additionally, due to the known heights of the camera modules, the system can determine the distance between the leaves and the ground, which provides crucial information for plant scientists.
The angle of the leaves is a key factor in plant architecture and photosynthesis efficiency. As explained by Assistant Professor Lirong Xiang from North Carolina State University, “In corn, you want leaves at the top that are relatively vertical, but leaves further down the stalk that are more horizontal. This allows the plant to harvest more sunlight. Researchers who focus on plant breeding monitor this sort of plant architecture because it informs their work.”
To test the effectiveness of the AngleNet system, the researchers compared the leaf angles measured by hand with those measured by the robotic system. The results showed that the measurements were within a five-degree range, which falls well within the accepted margin of error for plant breeding purposes. This groundbreaking technology holds significant potential for expediting plant breeding research, ultimately leading to improved crop yield.
The research on the AngleNet system has been published in the Journal of Field Robotics. The team is already collaborating with crop scientists to implement this technology, and they are hopeful that more researchers will adopt it to enhance their work. With its ability to quickly and accurately measure leaf angles, the AngleNet robotic system is revolutionizing the field of plant science and paving the way for advancements in agriculture.

Summary: New Robotic System Accurately Assessing Corn Plant Health Through Leaf Angle Measurements
A new robotic system developed by a team from North Carolina State University and Iowa State University, called AngleNet, can quickly and easily measure the angle of corn plant leaves relative to the stem. The system uses a wheeled robot equipped with four camera modules, which capture stereoscopic side-view photographs of the leaves on each plant at different heights. The images are then used to create three-dimensional models of the leaves, allowing researchers to calculate their angles. In testing, the measurements taken by the AngleNet system were found to be within an acceptable margin of error. This technology has the potential to greatly facilitate plant breeding research and improve crop yield.
