Approaches for Automated Monitoring and Evaluation of In Vitro Plant’s Morphometric Parameters

Abstract

The article discusses approaches to solving the problem of precise and objective registration and assessment of In Vitro plant’s morphometric parameters. Evaluating the impact of different nutrient media composition at different stages of plant development can help to choose the right nutrient medium and get high-quality virus-free planting material. The process of manual measurements of plant growth parameters violates the microclimate formed for optimal plant development, assumes inaccuracies due to the influence of the human factor and requires processing large volumes of heterogeneous data. The described disadvantages of manual measurements justify the prospects of using modern information technologies, methods and tools for automation and modeling, which allows conducting monitoring, evaluating and predicting the growth and development of plants In Vitro. Today, there are various hardware and software systems for photographing plants and assessing their morphometric parameters. However, such systems do not take into account the location of plants behind the glass of the test tube, which introduces image distortions due to fogging and glass defects, non-linearity at the boundaries of the tube, glare and reflection of the glass. This article proposes a prototype of an automated system for photographing plants from different angles, creating a 3D volumetric model of the plant and calculating morphometric parameters at various stages of plant development.
