Conventional professional or inexpensive color digital cameras can also be used for image acquisition (for Color Index analyses not for NDVI). We do not sell such cameras (as almost any model can be used) but we offer the Portable Imaging & Calibration Kit (PICK) to ease sample positioning and pixel size or color calibration.
The PICK allows to acquire images of leaves and other biological samples (needles, roots, ...) in fields (or laboratory) with a camera for their analysis in our software programs (WinCAM, WinFOLIA, WinSEEDLE, ...).
It contributes in different ways to obtaining good images suitable for precise automated analysis. The background provides good contrasts with biological samples. The translucent non-reflective cover holds them firmly against it to avoid shadows and distorted measurements. Calibration targets allow to make a fast and precise calibration in just one click.
The camera is held above the sample using a tripod (not included) with or without an extension arm and uses the ambient light (it works under sunny or cloudy days). To avoid fuzziness due to the depress of the shutter, we recommend to trigger the camera using the camera built-in timer or a remote control.
The PICK comes in two sizes to accomodate small or large objects or more of them per image and two models. One is optimized for color and morphology analysis (disease quantification, area per color, leaf or object area...) using the Pro versions of our software programs, the other for basic area and morphology analyses (grey levels analysis).
The PICK is a good complementary item to our scanner based systems.
