Computer vision is a field that involves making machine "see". This technology uses camera and computer instead of the human eye to identify, track measure targets for further image processing. With development vision, such has been widely used in agricultural automation plays key role its development. review systematically summarizes analyzes technologies challenges over past three years explores future opportunities prospects form latest reference researchers. Through analyses, it found...
The harvesting of fresh kiwifruit is a labor-intensive operation that accounts for more than 25% annual production costs. Mechanized technologies are thus being developed to reduce labor requirements kiwifruit. To improve the efficiency robot picking kiwifruit, we designed an end-effector, which report herein along with results tests verify its operation. By using established method automated discussed in literature and based on characteristics propose pick consists separating fruit from...
Abstract Background Plant shape and structure are important factors in peanut breeding research. Constructing a three-dimension (3D) model can provide an effective digital tool for comprehensive quantitative analysis of plant structure. Fast accurate always the goals 3D reconstruction Results We proposed method based on dual RGB-D cameras quickly accurately. The two Kinect v2 were mirror symmetry placed both sides plant, point cloud data obtained filtered twice to remove noise interference....
The spatial and energy resources available on small underwater platforms are limited, imposing strict restrictions the structure, weight, channel count of sonar array they carry. To enhance direction arrival (DOA) estimation capabilities platform sonars under these constraints, this paper examines a combined vertical (CVA), composed single vector hydrophone pressure hydrophones. line is insensitive to azimuthal variations, but CVA capable horizontal with better gain compared hydrophone. A...
Maize ( Zea mays L.) is one of the most important crops, influencing food production and even whole industry. In recent years, global crop has been facing great challenges from diseases. However, traditional methods make it difficult to efficiently identify disease-related phenotypes in germplasm resources, especially actual field environments. To overcome this limitation, our study aims evaluate potential multi-sensor synchronized RGB-D camera with depth information for maize leaf disease...
Maize (Zea mays L.), one of the most important agricultural crops in world, which can be devastated by lodging, strike maize during its growing season. lodging affects not only yield but also quality kernels. The identification is helpful to evaluate losses due natural disasters, screen lodging-resistant crop varieties, and optimize field-management strategies. accurate detection inseparable from determination degree helps improve field management crop-production process. An approach was...
Maize is among the most important grain crops. Aboveground biomass (AGB) a key agroecological indicator for crop yield prediction and growth status monitoring, etc. In this study, we propose two new methods, improved algorithm (iCBA) iCBA with piecewise function (iCBA-PF), to estimate maize AGB. Multispectral (MS) images, visible-band (RGB) light detection ranging (LiDAR) data were collected using unmanned aerial vehicles (UAVs). Vegetation indices (VIs) VI-weighted canopy volume model...
Abstract The novel europium complex acrylato(1,10‐phenanthroline)bis(2‐thenoyltrifluoroacetonato)europium( III ) [Eu(tta) 2 (aa)(phen)] [Eu‐AAPhen; Htta = 4,4,4‐trifluoro‐1‐(2‐thienyl)‐1,3‐butanedione, Haa acrylic acid, phen 1,10‐phenanthroline], which combines the excellent fluorescence properties of 3 (phen)] and reactivity acid with radicals, has been synthesized. Various amounts this (powder) are mixed nitrile‐butadiene rubber (NBR) peroxide to form uncured composites. These composites...

Lattice strain distributions mapped by high energy X-ray diffraction (see Figure) in an electrodeposited iron coating with nanocrystalline grains show nonlinearity, providing unambiguous evidence for the existence of a strong stress interaction along growth/deposition direction layered material.
Reliable and continuous information on cropping intensity is crucial for assessing cropland utilization formulating policies regarding protection management. However, there still a lack of high-resolution maps recent years, particularly in fragmented agricultural regions. In this study, we combined Landsat-8 Sentinel-2 imagery to generate from 2019 2023 at 10 m resolution Shaanxi Province, China. First, the satellite was harmonized construct 10-day composite enhanced vegetation index (EVI)...
Abstract Long‐term monoculture of watermelon results in inhibited growth and decreased crop yields, possibly because imbalance microbial ecology caused by accumulation the pathogen soil. This serious problems economics production. We investigated build‐up F usarium soil under cultivation changes over 3 yr fallow a microcosm. focused on community usarium‐infected soil, including diversity microfloral species composition, abundance. leads to structure. The microbes most readily cultured from...
Spaceborne Synthetic Aperture Radar (SAR) is one important way to obtain the information of ocean surface velocity. The Doppler Centroid Anomaly (DCA) estimation, which radical velocity based on difference between measured centroid and predicted centroid, have be used most onboard spaceborne SAR.

Seasonal forecasts of crop yield are important components for agricultural policy decisions and farmer planning. A wide range input data often needed to forecast in a region where sophisticated approaches such as machine learning process-based models used. This requires considerable effort preparation addition identifying sources. Here, we propose simpler approach called the Analogy Based Crop-yield (ABC) scheme make timely accurate prediction regional using minimum set inputs. In ABC...
In order to better understand the effects of neonicotinoid seed treatment (NST) on growth maize and soil microbial community, we conducted a field trial by planting seeds treated with thiamethoxam (TMX) TMX/difenoconazole (DFZ). All pesticide residues exhibited significant decreasing trend from seedling milk period (74 days post-sowing), majority them were found in roots leaves. None pesticides was detected kernels at harvest. The NST/TMX affected bacterial abundance community structure...
