Crop Health Monitoring
Crop Health Monitoring (Multispectral Sensor)
Overview
Multispectral drones provide wide-ranging applications across agriculture and environmental monitoring. In precision agriculture, they deliver detailed crop health mapping by detecting early signs of disease, pest infestation, nutrient deficiency, and water stress. This enables targeted interventions such as optimized fertilization and irrigation, improving yields while reducing resource wastage.
Process Flow
This image represents the working process of our drone equipped with a multispectral camera. As the drone flies over the target field, the multispectral camera captures images at different wavelength bands such as 490 nm, 550 nm, 680 nm, 720 nm, 800 nm, and 900 nm. These images help record the light reflectance from crops and soil in various spectral ranges. At the same time, the spectrometer collects detailed reflectance data from a specific area to maintain radiometric accuracy and ensure reliable calibration. The captured data layers are then combined to generate a image, which provides information on crop health, nutrient levels, and stress conditions. This process enables Drishti drone to deliver accurate, data-driven insights for precision agriculture and field monitoring.

Disease and Pest Detection
Disease & Pest Detection (AI Analysis)
Overview
AI-driven disease and pest detection uses high-resolution drone imagery, multispectral data, and machine-learning algorithms to identify early signs of crop stress, infections, and pest infestations. By analyzing patterns such as discoloration, canopy texture changes, chlorophyll variations, and thermal anomalies, the system can detect issues long before they become visible to the human eye. This enables farmers to take rapid, targeted action—reducing crop losses, minimizing chemical usage, and improving overall field health. Automated alerts, geo-tagged reports, and severity mapping ensure precise interventions and significantly higher operational efficiency in modern precision agriculture.
Process Flow
Plant Disease Detection Using Computer Vision in Agriculture | ImageVision.ai
The workflow begins with collecting leaf images directly from the crop field, capturing samples of different plants such as potato, pepper, and tomato leaves showing disease symptoms. These images undergo preprocessing to enhance clarity by adjusting lighting, removing noise, and preparing them for analysis. After image acquisition, the cleaned dataset is stored and passed through data augmentation, where images are rotated, resized, and rescaled to increase dataset diversity and improve the model’s robustness. The augmented dataset is then split into two parts: a training dataset used to train the AI model and a testing dataset used to evaluate its accuracy. The AI model learns to recognize disease patterns during training, and once trained, it processes the testing data to detect leaf diseases automatically. Finally, performance analysis is carried out to measure how well the model identifies diseases, completing the full AI-powered disease detection pipeline

Irrigation Management
Irrigation Management for Water Stress Zones
Overview
Irrigation management for water stress zones focuses on identifying areas within a field where crops are experiencing low moisture levels and require timely water supply. Using drone-based multispectral imaging, thermal maps, and soil moisture data, farmers can precisely detect dry patches, uneven water distribution, and stressed vegetation. The insights enable targeted irrigation rather than uniform watering, reducing water wastage while improving crop health and yield. This approach supports efficient water resource planning, early stress detection, and optimized irrigation scheduling for sustainable farm operations.
Process Flow
The process flow illustrates how drones streamline irrigation management through a connected, data-driven approach. It begins with water distribution mapping, where imaging sensors capture field-level variations to identify zones that are overwatered or underwatered. This data then supports scheduling and automation, enabling timely and precise irrigation based on AI-driven analysis. Using these insights, drones contribute to water conservation by optimizing water usage and minimizing wastage through real-time soil moisture intelligence. Continuous remote monitoring allows farmers to oversee irrigation activities from a centralized location, reducing manual field intervention. Finally, soil moisture monitoring ensures accurate assessment of moisture levels across the farm, helping prevent irrigation imbalances and improving overall crop health and water efficiency.

Soil Analysis and Mapping
Soil Analysis & Mapping
Overview
Soil analysis and mapping is a precision agriculture process that evaluates the physical, chemical, and biological properties of soil to understand its fertility, nutrient status, moisture levels, and overall productivity potential. Using sensors, laboratory tests, drones, and GIS tools, the system generates spatial soil maps showing variations across the field, enabling farmers to make data-driven decisions. These maps help in optimizing fertilizer application, irrigation planning, crop selection, and soil health improvement practices. The result is improved resource efficiency, higher yield, and sustainable field management with reduced input wastage.
Process Flow
Image source : Workflow of digital soil mapping | Download Scientific Diagram
The digital soil mapping workflow begins with a drone capturing multispectral or hyperspectral imagery, elevation data, and surface reflectance, which act as spatial covariates showing variation in soil moisture, texture, organic matter, and nutrient-related signals. Along with this, a few ground soil samples are collected to provide accurate reference values. These drone layers and soil sample results are then combined in a modeling system that applies depth-integrating functions to interpret soil properties vertically (Z-axis) and spatial scaling functions to map horizontal field variability (X–Y axis). Using machine learning, the system correlates drone-derived data with measured soil values to predict soil characteristics across the entire field. The final output is a 3D soil property map showing nutrient levels, pH, EC, organic carbon, texture, and moisture for different soil depths, enabling precision decisions for fertilization, irrigation, and soil health management.
