Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News-New research on robotics is the subject of a new report. According to news reporting originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "The rise of mechanical aut omation in orchards has sparked research interest in developing robots capable o f autonomous tree pruning operations. To achieve accurate pruning outcomes, thes e robots require robust perception systems that can reconstruct three-dimensiona l tree characteristics and execute appropriate pruning strategies." Funders for this research include Contract Research of Non-government Funded Pro jects. The news editors obtained a quote from the research from Beijing Forestry Univer sity: "Threedimensional modeling plays a crucial role in enabling accurate prun ing outcomes. This paper introduces a specialized tree modeling approach using t he space colonization algorithm (SCA) tailored for pruning. The proposed method extends SCA to operate in three-dimensional space, generating comprehensive cher ry tree models. The resulting models are exported as normalized point cloud data , serving as the input dataset. Multiple criteria decision analysis is utilized to guide pruning decisions, incorporating various factors such as tree species, tree life cycle stages, and pruning strategies during real-world implementation. The pruning task is transformed into a point cloud neural network segmentation task, identifying the trunks and branches to be pruned. This approach reduces th e data acquisition time and labor costs during development. Meanwhile, pruning t raining in a virtual environment is an application of digital twin technology, w hich makes it possible to combine the meta-universe with the automated pruning o f fruit trees. Experimental results demonstrate superior performance compared to other pruning systems."
