Design and Development of Plant’s Growth Measurement System

Abstract

Growth of plant is influenced by environmental conditions and topography. So there is need to measure dynamics of plant to understand how plants respond to variation in water content and long term water conditions. Various studies have found that variation of the diameter and height of plant stem has an important correlation ship with water status, temperature, light and humidity. Here, an interface between a C3008 smart camera and a computer has been developed. This camera module has digital output and digital video port that supplies a continuous 8-16 bit range of data stream. It is used to capture the images of a plant. A MATLAB GUI has been developed for performing Sobel Edge Detection on a plant image to determine its height, maximum and minimum width. Testing of different plants is done at different locations. The results attained prove that the system is capable of measuring the changes (diameter and height changes) of plant's growth accurately.
