Can machine vision inside a vertical farm automatically detect crop growth stagnation?

Vertical farming, a method of growing crops in vertically stacked layers, has gained significant traction in recent years due to its potential to increase crop yields while minimizing land and water usage. However, ensuring optimal crop growth and detecting stagnation is crucial for maximizing yields and minimizing losses. Machine vision, a subset of computer vision, has emerged as a promising solution for monitoring crop health and detecting anomalies in growth patterns. In this report, we will explore the feasibility of using machine vision inside a vertical farm to automatically detect crop growth stagnation.

1. Background and Challenges

Vertical farming involves growing crops in vertically stacked layers, often in indoor environments. This method allows for year-round production, reduced land usage, and improved crop quality. However, vertical farming also presents unique challenges, including optimal temperature and humidity control, precise watering, and monitoring of crop growth. Detecting crop growth stagnation is critical to preventing losses and ensuring optimal yields.

Crop growth stagnation can occur due to various factors, including inadequate watering, nutrient deficiencies, pests, and diseases. Conventional methods for detecting stagnation involve manual inspections by farmers, which can be time-consuming and prone to human error. Furthermore, these methods often rely on subjective assessments, making it challenging to detect subtle changes in crop growth.

2. Machine Vision and Computer Vision

Machine vision is a subset of computer vision that involves the use of algorithms and software to interpret and understand visual data from images and videos. In the context of vertical farming, machine vision can be used to monitor crop growth, detect anomalies, and provide insights for data-driven decision-making.

Computer vision has gained significant attention in recent years, with applications in various industries, including agriculture, healthcare, and manufacturing. The technology has evolved significantly, with advancements in deep learning, convolutional neural networks (CNNs), and transfer learning.
