CID - Model CI-110 - Plant Canopy Imager

SHARE
Your data through a new lens. The CID Bio-Science Plant Canopy Imager makes data collection a breeze, allowing you to focus on the metrics that matter. Crop optimization: Measure vegetative spectral response, estimate plant nutrition, water requirements, and plant stress to enhance crop yields. Forest productivity: LAI, PAR and sunflecks inform silviculture, forest restoration, and the optimization of yields and wood quality. Environmental research: Use canopy data to develop a greater understanding of the impacts of climate change, and human activity on the natural world.

Leaf Area Index (LAI) is defined as one sided leaf area divided by the total ground area. Photosynthetically Active Radiation (PAR) designates the spectral range of solar radiation (400-700 nm). By measuring PAR and LAI simultaneously, one is able to calculate LAI and canopy parameters using a variety of methodologies.

To calculate LAI, the CI-110 captures a 150° fisheye image of the canopy, which is divided into zenith and azimuthal divisions. Using the software included on the tablet computer, the user can include or exclude any zenith and azimuth division to focus on specific portions of the canopy for study.

The most practical method for non-destructive LAI measurement is the Gap Fraction Method. Gap Fraction indicates how much of the sky is visible from beneath the plant canopy. The greater the area of sky that is visible, the larger the gap fraction.

When using the CI-110, a value between 0 and 1 is assigned to estimate the Gap Fraction in a canopy—0 means that no sky is visible below the plant canopy whereas 1 means that the entire area is sky is visible, or there is no foliage coverage. Any fraction indicates partial foliage cover.

Images taken with the CI-110 are divided into sectors according to the user-selected number of zenith and azimuthal division. The fraction of the sky (solar beam transmission coefficient) that is visible in each sector is automatically analyzed by tallying the sky portion of the image pixels in that sector. Once all sectors are analyzed and the average solar beam transmission coefficients for each zenith division are computed, the hemispherical diffuse radiation transmission coefficient (the sky view factor), mean foliage inclination angles, and plant canopy extinction coefficients are instantaneously computed by CI-110`s analysis software.
