To automate these processes it is essential to understand the complexity and variability of their three-dimensional (3D) shape as well as the relationship between their outer shape and inside bone structure. In this paper, we introduce a 3D statistical shape model (SSM) that describes the outer surface of a pork shoulder and its corresponding inner bone structure. X-ray computed tomography (CT) scans were acquired from 45 right-hand side and 45 left-hand side pork shoulders. The CT scans were segmented to obtain 3D models of the external shape and internal bone structure. Surface meshes were then created and used for establishing SSMs of the outer surface, the bone structure and the combined surfaces of the left and right pork shoulders based on principal component analysis. The first five of a total of 40 principal components were able to describe 63.6 % of the variability in the entire dataset. The mean absolute error (MAE) of the proposed fitting method in this paper was 5.15 mm for the test set. Besides being compact, the models could also generate realistic 3D shapes of pork shoulders that were not present in the dataset. These shapes can be used in the development of automated cutting and deboning procedures, and, thus, lead to improved precision in cutting, reduced waste, and further enhancements of automation within the meat industry.</div></div>","PeriodicalId":50627,"journal":{"name":"Computers and Electronics in Agriculture","volume":"237 ","pages":"Article 110666"},"PeriodicalIF":7.7,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite much progress made in the harvesting process from detection to picking, these technologies are not yet commercially viable. One of the limiting factors for increased performance is fruit occlusion in canopies, particularly in the open-field environments. There has been only limited studies on active occlusion handling/removal techniques during robotic picking. This paper presents the development and evaluation of a strawberry harvesting robot focusing on occlusion handling in open-field environments using vision-based occlusion information and novel end-effector design. The robot was composed of an integrated machine vision system based on deep learning techniques, a 6 DOF manipulator, and an innovative end-effector equipped with a fan system, and a mobile platform. Based on the classification of detected strawberries (‘not occluded’ or ‘occluded’), the robotic platform followed specific steps for directly picking the strawberries (if not occluded) or removing/dispersing the occlusion over the strawberries (if occluded) and subsequently picking them. The effectiveness of this harvesting robot including fruit recognition & localization, and picking method was evaluated using multiple experiments in both the simulation field and the real field. The results showed that the mean average precision in strawberry detection was 80.5% and classification accuracy was 93.2%. Picking efficiency of the robot was enhanced substantially by the use of fan system. In an outdoor strawberry field, the robot achieved a picking rate of 58.1% without fan system, which increased to 73.9% with the fan system (a 15.8% increase in fruit picking rate). It was found that the average processing time of machine vison system was 6.26 s and the overall average time to pick single strawberry with the fan system for removing occlusion was 20.1s.</div></div>","PeriodicalId":50627,"journal":{"name":"Computers and Electronics in Agriculture","volume":"237 ","pages":"Article 110684"},"PeriodicalIF":7.7,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gripper employs biomimetic conical fingers inspired by the fin-ray effect, which were structurally reconstructed and optimized based on fish-fin architecture, mechanical modeling, and simulation experiments. A flexible force-sensing sensor based on a triboelectric nanogenerator (TENG) was developed and integrated into the fingers to enable precise force feedback perception and enhance the detachment capability of the gripper.

The MDS-PointPillars model primarily consisted of two components: the pillar feature net (PFN) and the backbone. In the PFN component, a multi-pooling encoding module (MPE) was designed, which integrated max-pooling, average-pooling, and attention mechanisms to improve the extraction of multi-scale point cloud features. In the backbone component, a depthwise separable convolution block (DSB) was designed to reduce computational complexity while enhancing the perception of both local and global features. Additionally, the model incorporated a parameters-free simple attention module (SimAM), which adaptively strengthened the focus on key point cloud features, further improving the identification accuracy of rare and hard-to-classify obstacles. Experimental results showed that MDS-PointPillars achieved a mean average precision (mAP) of 90.8 % on the test set of person, agricultural machinery, and utility poles in farmland, with an inference speed of 20.1 FPS and a model size of only 13.1 MB, significantly reducing computational burden.

The current lack of efficient methods for high-throughput phenotyping WUE hinders development of sustainable agriculture under globally intensified water scarcity. This study aimed to utilize unmanned aerial vehicle (UAV) multisensory remote sensing data combined with a process model to achieve rapid WUE determination via accurate daily-scale evapotranspiration and aboveground biomass (AGB) estimates. First, vegetation indices, canopy temperature, and canopy structural parameters were extracted from multispectral (MS), thermal imaging (TIR), and radar data and combined with an automated machine learning (AutoML) for AGB estimation. The beta function was then employed to accurately estimate AGB accumulation at a daily step (<em>AGB</em><sub>daily</sub>) over the entire growth period. The daily evapotranspiration (<em>ET</em><sub>daily</sub>) was calculated by the surface energy balance algorithm for land (SEBAL) model driven by MS, TIR, and meteorological data. Finally, the WUE was determined by the ratio of <em>AGB</em><sub>daily</sub> to <em>ET</em><sub>daily</sub>. Multisensory data fusion and further integration with process-based model proved effective for simultaneously estimating <em>AGB</em><sub>daily</sub>, <em>ET</em><sub>daily</sub>, and WUE with R<sup>2</sup> values of 0.71, 0.93, and 0.79, respectively. Notably, the proposed WUE estimation method can capture different temporal pattern between cultivars with different levels of tolerance to drought. We applied this approach to screen water efficient cultivars and found that appropriate reduction of irrigation can improve WUE.

This study aimed to refine the encoding process of matrix barcode GCPs, with objectives that included (1) evaluating the performance of several barcode types for use in GCP applications; and (2) assessing different compression methods for encoding geographic coordinates within the barcodes.
