Pruning Points Detection of Sweet Pepper Plants Using 3D Point Clouds and Semantic Segmentation Neural Network

Abstract: Automation in agriculture can save labor and raise productivity. Our research aims to have robots prune sweet pepper plants automatically in smart farms. In previous research, we studied detecting plant parts by a semantic segmentation neural network. Additionally, in this research, we detect the pruning points of leaves in 3D space by using 3D point clouds. Robot arms can move to these positions and cut the leaves. We proposed a method to create 3D point clouds of sweet peppers by applying semantic segmentati… Show more

“…It uses the ORB and BA algorithms to extract feature points and optimize camera poses in local or global maps. Due to its advantages, we proposed a method to create 3D point clouds by using ORB-SLAM3 and then optimizing the result with the help of the Iterative Closest Point (ICP) method [ 21 ]. The process is described in Figure 2 .…”

“…Giang and Ryoo (2023) introduced an approach using semantic segmentation neural networks (NN), the ICP algorithm and ORB‐SLAM3, a visual SLAM application with a LiDAR camera, to create 3D‐point clouds of sweet peppers. An improved structure from motion (SFM) and patch‐based multiview stereo (PMVS) method based on similar graph clustering and graph matching are proposed by Zhang et al (2023) to perform 3D sparse and dense reconstruction of green plums by utilizing computer vision technology.…”

“…Utilizing machine vision techniques to acquire image-based 3D models of seedlings offers several advantages. It eliminates the need for strict research environments, mitigates costly expenses, and enables the capture of color, texture information, and improved measurement precision [26,27]. Sun et al [28] proposed a high-throughput, three-dimensional rapid plant point cloud reconstruction method based on autonomous calibration of the Kinect v2 sensor position.…”
