Extraction of phenotypic traits using unmanned aerial vehicle for field experiments in the agronomy and crop breeding

With advances in camera and robotic technologies, unmanned aerial vehicles (UAV) provide the means to capture images at sufficiently large scale to extract crop phenotypic traits. The current challenges are to efficiently manage the meta information …

Estimation of plot variability using unmanned aerial vehicle (UAV) for the wheat breeding trials

Gaps in breeders’ plots (spatial variability) are caused by multiple biotic and abiotic stresses (i.e. poor seed gemination, frost, heat, drought, and/or disease). The gaps are either ignored or visually scored by human inspection. However, this …

The big impacts of image resolution on the estimation of ground coverage for wheat in UAV survey

Ground coverage (GC) is a simple and important trait to monitor crop growth and development, which can be easily captured by visual camera attached on the ground and aerial based platform. However, the accuracy of GC is determined by pixel size …

EasyPCC: Benchmark Datasets and Tools for High-Throughput Measurement of the Plant Canopy Coverage Ratio under Field Conditions

Understanding interactions of genotype, environment, and management under field conditions is vital for selecting new cultivars and farming systems. Image analysis is considered a robust technique in high-throughput phenotyping with non-destructive …

Comparison of ground cover estimates from experiment plots in cotton, sorghum and sugarcane based on images and ortho-mosaics captured by UAV

Ground cover is an important physiological trait affecting crop radiation capture, water-use efficiency and grain yield. It is challenging to efficiently measure ground cover with reasonable precision for large numbers of plots, especially in tall …

The gravel coverage and size of Gobi desert analyzed by a rapid image-based method

The Gobi desert is one of the most widespread landscapes in northwest China. The coverage and morphological characteristics of gravels on the Gobi desert are often used to understand the evolution process of Gobi desert. However, some traditional …
