CI-110 Digital Plant Canopy Imager
Auto-level fish-eye camera for forest study
|
|
The CI-110 Digital Plant Canopy Imager can capture and analyze images using its fish-eye lens (150°) and CCD camera. It consists of an image-capturing probe (the lens, camera and auto-level gimball), and arm with 24 PAR sensors and built-in USB interface, and optional laptop computer, and software.
You can see a live high-resolution fish-eye image when you hold the probe under the plant or forest canopy. After the image is captured, the software quickly calculates the solar beam transmission coefficients using a user-defined number of zenith and azimuthal divisions. The gap-fraction inversion procedure (Normal and Campbell, 1989)* is used to calculate Leaf Area Index of the canopy, diffuse radiation transmission coefficients, mean foliage inclination angles, and plant canopy extinction coefficients. The output data is then displayed on the computer screen and can be saved in a text file.
- Only one single measurement required.
- 150°-wide viewing angle and high-resolution fish-eye image.
- Non-destructive measurement of Leaf Area Index (LAI) and PAR.
- On-site evaluation of solar beam transmission coefficients or gap fractions.
- Calculation of diffuse radiation transmission coefficients (the sky view factor), mean foliage inclination angles, and plant canopy extinction coefficients.
- User-selected number of zenith devisions (rings) and azimuthal divisions allows investigation of any canopy sectors desired.
- Sun path can be easily plotted on the image.
- A Bar of PAR sensors (24 sensors) to measure Sun Flecks in the range of Photosynthetic Active Radiation.
