WAGENINGEN, Netherlands – Machine vision technologies can help improve food production right at its roots by helping farmers identify and kill weeds in their fields. Researchers at Wageningen University have developed a system that automatically does just that; such a system could help raise productivity, lower costs and protect the environment. The researchers, who work in the university’s Farm Technology Group, set out to develop a system that would recognize and attack a weed called the wild potato, which can be a nuisance to sugar beet farmers. When crops are rotated from potatoes to beets, the leftover...Read full article

    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
    scanner
    1. A device used to trace out an object and build up an image. One of the most common of these types is video scanning. The scanning takes place inside the television tube as electrons, guided by electron optics, sweep linearly across a tube face coated on the inside with a phosphorescent material. A scanner can convert a paper drawing or photograph into pixels on a display screen. Scanners are also used to relay information in optical data processing. 2. A device that automatically measures or...
    sensor
    1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
