FAQ

  • The effect of adjusting the brightness depends on whether it is done during image acquisition or afterwards, during image processing. If you have already taken the image and are now processing it afterwards, the following relationship is expected: LAI will decrease with increasing brightness.
  • This is because plant elements, such as back-lit leaves or light green leaves, will be washed-out in the photo and will appear as sky to the software. Increased brightness= more sky = decreased LAI. To counter-act this, re-assign "Foliage" and "Sky" colors in the Sky and Leaf Filter option after setting the desired brightness.
  • It is recommended to:
    1. Adjust the brightness so the image appears properly exposed.
    2. Go to the Threshold menu and choose a method.
    3. Adjust the slider until all the plant elements appear green.
    4. Press the Data button.
    5. Go back and adjust the brightness/contrast until all the plant elements are green.
    6. Keep tweaking the settings until you have grouped all the plant elements together and separated the sky or background.

  • The key is that there are several files required to load a record. You have to move all those files to migrate data between systems. You should copy the entire "Output Folder" contents to the new system using an SD Card, USB drive, WiFi, etc. or use something like Microsoft's SyncToy to keep the folders on the tablet and PC automatically in sync.

  • Go to the Advanced Settings tab and change the Top and Left offsets to the values in the Product Test Check Sheet page of this manual.

  • Yes, this is normal. The power to run the PAR sensors and camera run through the handle of the stick. This generates the heat in the handle.

  • The bottom of the camera mount has a cable attached to it and the stick has opaque white plastic on the top.

  • The PAR sensors are located in the stick the camera connects to.

  • The CI-110 camera was modified to use a blue lens, the contrast and other parameters have been adjusted for optimum accuracy. Indoor lights aren’t usually strong enough to show anything other than a dark or black image.

  • Browse to the image you want to use, then drag-and-drop your image on the Measurement screen.

  1. New and improved camera and filter.
  2. New and improved GPS.
  3. Updated software with many bug fixes.

For more information on Gap Fraction Methods please refer to the article by Juarez et al. "An improved estimate of leaf area index based on the histogram analysis of hemispherical photographs."

  • Software version 5.3.1 includes a fix to a bug that prevented the software from properly controlling the camera exposure. Images taken with previous versions of software may appear darker when opened in version 5.3.1. After properly adjusting the exposure, the image should appear correctly.

For types of canopies that work well with the CI-110, please refer to the list of published research (http://cid-inc.com/ci-110-publications). The CI-110 has been used to effectively measure the LAI of forests, rice, pastureland, sub-Mediterranean grasslands, winter wheat, Quercus species, Shpaeralcea and Shepherdia species, Amaranthus powellii, Erythroxylum coca, Olea europaea, and Cypripedium flavum, among others.


  • Unfortunately, due to their irregular canopy shape, the gap fraction method for calculating the Light Area Index of canopies of grapes grown on vertical trellises cannot be accurately measured. So neither instrument can be recommended for the study of grape canopies.

  • The CI-110 lens probe and the accompanying software that calculates Leaf Area Index was designed to measure forest canopies. The CI-120 compact lens probe was designed later to measure in rice paddies and wetland conditions where the CI-110 lens probe could not get low enough to take the image. The current CI-110 has even lower clearance than previously, so the CI-120 is no longer offered.
  • The self-leveling feature of the CI-110 is a very significant advantage when measuring tree canopies. The CI-110 lens probe has a 150° viewing angle.
  • Due to advances in the CI-110 hardware, the CI-120 has become obsolete.  The CI-110 current hardware is capable of taking measurements of short canopies, starting at 31 cm above the ground.  

  • The tick or arrow-tip on the outside of the image will change from red to green when the CI-110 camera and wand are pointed north. North or green is at the 12 o’clock position on the image.

  • Position: 5m CEP without SA
  • Velocity: 0.1m/sec, without SA
  • Time: +/- 50ns synchronized to GPS time
  • CEP is Circular Error Probability. CEP is defined as the radius of a circle centered on the true value that contains 50% of the actual GPS measurements. So a receiver with 1 meter CEP accuracy will be within one meter of the true measurement 50% of the time. The other 50% of the time the measurement will be in error by more than one meter.

  • The GPS can take up to 15 minutes to locate satellites and establish longitude, latitude and altitude parameters. This time should be shorter after the initial connection. The GPS typically needs to be outdoors to connect to satellites.

  • The CI-110 driver compatibility is hardware specific.  Please check your serial number to determine if your hardware is compatible with 64 bit systems.  
  • Serial numbers with the middle three digits of 2.13 or higher are compatible with 64 bit systems and CI-110 software version 6.
  • Serial numbers with the middle three digits of 2.12 or lower are compatible only with 32 bit systems and CI-110 software version 5.3.

  • The latest version of software and the driver can be downloaded at http://cid-inc.com/Software/CI-110/v6/
  • Click the “Install” button to start the download. If prompted that the publisher is not verified, click Run or Install to continue the setup.
  • Next, install the driver according to the Instruction Manual.

ANSWER!!!


What should I do if my CI-110 is not recognized by the tablet computer?

1. Open the CI-110 software and go to the "Advanced" tab.  Install the driver.

2. If the tablet is Windows 8, make sure that the driver signature verification is disabled.  Due to certificate expiration, it may be necessary to disable the driver signature verification after a recent Windows update.

3. Install the driver and verify CI-110 is recognized in the Device Manager.


In the CI-110 Plant Canopy Analysis software, it is important to check out the exposure of the camera before saving a canopy image. The exposure of the camera should allow you to clearly see the canopy and sky gaps, without being too bright or too dark.  If the image is out of focus, twist the lens of the camera to make it crisp and clear.  Finally, verify that the "color control" of the picture is showing a realistic representation of the canopy.  Then, capture the image and make sure to hold the camera steady for 1-2 seconds while the image is saved.  All other adjustments or edits in the software can be made to the saved image.

The CI-110 is not designed to be waterproof and should not be used underwater. The CI-110 is designed to be water-resistant. Use in light rain is fine, however, there are electronics inside of the CI-110 that can be damaged from water entering the instrument, so it is not recommended to use the CI-110 during heavy rainfall. Furthermore, it should be noted that the tablet provided with the CI-110 is not waterproof and a waterproof case would need to be purchased for use in wet conditions.
