Triangular Greenness Index (TGI) is calcultated from the area of a triangle that is defined by 3 points for the reflectance pf wavelength (480nm, R480, 550nm, R550 and 670nm, R670, R= Reflectance of wavelength). The formula for TGI is: TGI = -0.5[190(R670 – R550) – 120(R670 – R480)] Article: U.S. Department of Agriculture: Agricultural ResearchService,
The selection of sensors (link) depends on your objectives. I.e., what do you wish to know from the image? Is it a stress level? If so, what type of stress? Below are some common examples of vegetative indices used to monitor crop health. Vegetation indices are crucial for assessing the health and growth of vegetation.
Introduction Precision agriculture workflows involve operation of aerial drones, sensors/cameras, and software applications. The goal is to gain valuable insights into your crops. In recent times, the number of growers using drones to collect crop and field data has increased significantly. Agriculture-specific applications have been developed to meet this demand. Users can plan autonomous flight
Many of us seek methods to optimize crop production by gaining more information from the field. Various technologies are available for grower’s aid electronic devices, sensors, data management applications, and artificial intelligence (AI) technology, to name a few. These trends became more critical in the past decade or so and became a center of research
Agriculturalists are moving towards applying more advanced technology in order to maximize crop production and workflow efficiency. Some technological advances that have been made are the development in artificial intelligence (AI), electronic devices, and sensors. These technologies are often applied to data collection such as crop count, plant disease assessment, drought monitoring, and soil analysis.
Major areas to look for focus in precision agriculture for 2023 include: Digital agriculture, robotics and automation, and sustainability practices. Robotics and Automation The areas to watch for robotics and automation to increase the efficiency for farm management are things like: pruning, thinning, harvesting, spraying, mowing, and weeding. Sensors, artificial intelligence (AI), and control systems
Dragonfish Series: Fixed Wing Drones: Autel Robotics has developed the Dragonfish Fixed Wing Series Drones. There are three versions in the series: Dragonfish Pro, Dragonfish Standard, and Dragonfish Lite. The flight times for each drone while carrying a payload are: 158 minutes, 126 minutes, and 81 minutes respectively. The Dragonfish Series is equipped with an
Yuneec H520E RTK Commercial Hexacopter Yuneec made these drones available to the public November 2020. They made these drones to target the needs for the inspection industry. The six rotor design enhances the stability and precision of drone flight. Its long focal-length camera lens gives you the ability to gather data further away from target
