Special Issue Information

Dear Colleagues,

With the continuously growing global population, the agricultural industry is facing tremendous pressure to increase crops’ yield and quality to meet the growing demand for food. At the same time, reducing the adverse environmental impact of agricultural activities has become an urgent task. In this context, unmanned aerial vehicle (UAV) imaging technology has introduced new solutions to the agricultural sector by providing high-resolution aerial images and data. Equipped with advanced imaging sensors, UAVs can capture subtle the changes in and features of plants, providing a detailed understanding of crop health. These sensors can measure indicators such as the chlorophyll content, leaf area index, and plant height, helping farmers and researchers monitor the crop growth conditions and potential issues. With UAV imaging technology, they can quickly detect crop pests, nutrient deficiencies, water stress, and take appropriate measures for management.

Furthermore, UAV imaging technology can also be used for crop biomass estimation and yield prediction. By collecting a large amount of UAV image data and combining image processing algorithms and machine learning techniques, researchers can establish accurate models to estimate the crop biomass and predict the yield. This provides crucial decision support for farmers, helping them optimize agricultural management and resource allocation, thereby improving the production efficiency and economic benefits.

In the current agricultural industry, which must meet the growing demand for high-quality agricultural products and reduce the environmental impact, UAV imaging technology has become a powerful tool in modern agriculture. The utilization of advanced imaging sensors and image processing algorithms is particularly important, with a specific focus on crop health, biomass estimation, yield prediction, and pest and disease forecasting.

In consideration of the limited accuracy of individual tree canopy segmentation algorithms due to the diverse canopy structure and complex environments in mountainous and hilly areas, this study optimized the segmentation parameters of three algorithms for individual tree canopy segmentation of Camellia oleifera in such environments by analyzing their respective parameters. Utilizing an Unmanned Aerial Vehicle-Light Detecting and Ranging (UAV-LiDAR) system, we obtained Canopy Height Models (CHM) of Camellia oleifera canopies based on Digital Elevation Models (DEM) and Digital Surface Models (DSM). Subsequently, we investigated the effects of CHM segmentation, point cloud clustering segmentation, and layer stacking fitting segmentation on Camellia oleifera canopies across different research areas. Additionally, combining ground survey data from forest lands with visual interpretation of UAV orthophoto images, we evaluated the performance of these three segmentation algorithms in terms of the F-score as an evaluation indicator for individual tree canopy segmentation accuracy. Combined with the Cloth Simulation Filter (CSF) filtering algorithm after removing the ground point cloud, our findings indicate that among different camellia densities and terrain environments, the point cloud clustering segmentation algorithm achieved the highest segmentation accuracy at 93%, followed by CHM segmentation at 88% and the layer stacking fitting segmentation method at 84%. By analyzing the data from UAV-LiDAR technology involving various land and Camellia oleifera planting types, we verified the applicability of these three segmentation algorithms for extracting camellia canopies. In conclusion, this study holds significant importance for accurately delineating camellia canopies within mountainous hilly environments while providing valuable insights for further research in related fields.
