NEW Triple Bandpass Filters for NDVI and ENDVI

Assess crop health quickly, inexpensively and in real-time using converted consumer cameras and unmanned aerial vehicles.

Palatine, Ill. (May 25, 2017) – Triple Bandpass Filters are tools that allow users to go above and beyond traditional Normalized Difference Vegetation Index (NDVI) indicators to reinvent the way crop health is monitored and to collect more information than ever before. Traditionally, true 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).

Select an Optical Filter to Suit Changing Conditions

Article Featured in Industrial Photonics

Optical filters have long been critical components in traditional machine vision applications. They maximize contrast, improve color and subject recognition, or otherwise control light reflected from an object under inspection. Typically, filters are used for machine vision tasks that do not vary much from product to product or from one subject to the next. However, recent advances in sensors, artificial intelligence, human-robot interaction and other technologies have led to the use of machine vision in more flexible applications such as sorting, material handling and automated assembly. When choosing a filter for these applications, consider the following.
