CI-110 Digital Plant Canopy Imager

Capture wide-angle plant canopy images while instantly estimating Leaf Area Index (LAI) and measuring Photosynthetically Active Radiation (PAR) levels. The digital, self-leveling camera, updated touch screen, and included filters work together to collect, calculate, and save data in any daylight condition.
New unit with delay trigger release capture and amplified antennae connected to four satellite constellations provides accurate, instant location data along with LAI measurements.

The new CI-110 combines hemispherical canopy photography and image analysis with light measurement to non-destructively calculate leaf area index (LAI) and other canopy parameters. The self-levelling digital camera takes 150° images of plant canopies and the 24 photosynthetically active radiation (PAR) sensors in the arm of the device measure light to calculate Sunflecks.

The upgraded, ergonomic design is paired with a 7″ capacitive touch screen, a trigger with delayed image release for crisp images, and the ability to add or exchange filters over the camera lens.

The CI-110’s digital platform enables you to simultaneously capture wide-angle plant canopy images and estimate Leaf Area Index (LAI) and Photosynthetically Active Radiation (PAR) levels from a single canopy scan. No more taking multiple scans above and below the canopy…leave your tree-climbing equipment at home. One measurement provides a full complement of data, unlike systems which require the user take multiple measurements and attach various masking devices to obtain meaningful data.

” Short of actually collecting leaves, which eliminates the opportunity to measure canopy change over time, hemispherical photography is the method of choice for measuring LAI.” (Jonckheere et al. 2004)

  • Instant Data: Captures Canopy image and calculates Leaf Area Index (LAI) and Photosynthetic Active Radiation (PAR) levels
  • Onsite Evaluation: The CI-110 digital process needs only one scan beneath the canopy, allowing on-site evaluation under any daylight conditions
  • User-Defined: User-selected number of zenith divisions (rings) and azimuthal divisions allows investigation of any canopy sectors desired
  • Lightweight: 0.5 Kg instrument is handheld and simple to use

Lightweight (500 grams) and fast, the CI-110 revolutionises data collection for forest management, crop science and environmental research!

The CI-110 Digital Plant Canopy Imager consists of an auto-levelling image capturing probe and arm with 24 PAR sensors, built-in USB interface for an optional laptop or palmtop computer, and software. To calculate PAR and LAI, the CI-110 captures a 150° fisheye image of the canopy, which can be divided into any number of zenith and azimuthal divisions desired. In this way, you may focus on all or any part of the canopy for study. The software digitises and manipulates the captured images, then calculates the solar beam transmission coefficients, or the fraction of the sky visible from beneath the plant canopy. A value between 0 and 1 is assigned; with 0 meaning no sky is visible below the plant canopy, and 1 meaning that the entire area is sky or no foliage coverage. A fraction indicates partial foliage cover.

Using the CI-110

Simply position the CI-110 under the desired leaf canopy. The auto-levelling fisheye camera lens (150°) displays a live image of the canopy for accurate data collection. Once you have captured the desired canopy image, software-driven analysis manipulates any data portion you desire, making manual image masking obsolete.

Calculations Performed:

  • Leaf Area Index (LAI)
  • Mean Foliage Inclination
  • Sunflecks – The fraction of visible sky from below the canopy
  • Photosynthetically Active Radiation (PAR)
