We want to optimize flight altitute and opeating speed for multispectral imaging for crop health monitoring in agricultural crops.
Ramesh Kumar Sahni
Based on what I have done:
Optimal flight altitude and speed are determined based on
- the target ground sampling distance (GSD),
- required image overlap for multispectral mosaics, and
- the camera’s capture rate and motion-blur limits.
Flights for crop monitoring should be conducted near solar noon under low wind conditions (
i have little information about this subject but u did gather some info its brief but i believe its accurate based on my info the optimal drone flight altitude and speed for multispectral imaging in cereal crops are determined by a trade-off between spatial resolution (GSD), data quality, and operational efficiency. The parameters depend on the sensor, illumination conditions, and specific agricultural goal. However, a strong consensus exists around the following parameters: Optimal Altitude: 30 to 120 m High-Resolution Tasks (e.g., early-stage disease detection): Fly lower, typically 30–40 m. Broad-Scale Mapping (e.g., nitrogen status): Fly higher, typically 60–120 m. Optimal Speed: 4 to 8 m/s Lower Speeds (4–5 m/s): Required when flying at lower altitudes or using sensors with slower capture rates to ensure sufficient image overlap (>75%) and prevent motion blur. Higher Speeds (6–8 m/s): Acceptable at higher altitudes and under bright, stable illumination conditions.
