Converted Consumer Cameras and Unmanned Aerial Vehicles Assess Crop Health – Featured in Inspect

Triple Bandpass Filters are tools that allow us to go above and beyond traditional Normalized Difference Vegetation Index (NDVI) indicators to reinvent the way we monitor crop health and collect more information than ever before.

Traditionally, NDVI was used to determine plant health, which incorporates a camera with a red and near-infrared (NIR) filter—and the equation NDVI = (NIR – Red)/(NIR + Red). While this is a great tool, scientific advances have found that modifying this calculation can provide even more details about crop and field health. Similarly to red light, healthy plants also absorb visible blue light. And in addition to NIR light, healthy plants also reflect some visible green light. These facts enable us to assess crop health quickly, inexpensively and in realtime using converted consumer cameras and unmanned aerial vehicles.

Key Features of a Quality Machine Vision Filter

Article featured in Automation Magazine

Optical filters are critical components for machine vision applications. They’re used to maximize contrast, improve color, enhance subject recognition and control the light that’s reflected from the object being inspected. A machine vision filter is not just a machine vision filter. Here’s what to look for when choosing a filter for your machine vision system:
