PLANT MONITORING BY MACHINE VISION

The purpose of the project was to establish the possibilities for using machine vision to determine parameters, important to the evaluation of biological material.
Pot plants were chosen as an example.

During the project, the ability of the camera, framegrabber and computer algorithms to distinguish between various colours were investigated.
Using colour samples, it was established that the system in fact was able to distinguish adequately between colours which, to the human eye seemed very close, as for instance flowers from two different varieties of a pot plant species.

Segmentating pot plants was tried using several different approaches of which the simple thresholding in RGB proved to be the best and fastest.

From the segmented picture, data relating to size, shape, regularity etc. were calculated.
