This is the primary prerequisite. For orchard inspection, prioritize a high-resolution visible light camera + multispectral camera for monitoring pests, diseases, and crop growth. Mine surveying requires a LiDAR + oblique photography camera to meet 3D modeling and earthwork volume calculation needs. Power line inspection can use an infrared thermal imaging camera to check for overheating faults in power lines

The key is the drone’s payload capacity. The payload weight must not exceed the drone’s maximum load capacity, and the impact of payload volume on the drone’s aerodynamic layout and flight stability must be considered. Secondly, flight time is crucial. High-power payloads (such as LiDAR) will shorten flight time; therefore, a low-power model or a backup battery should be selected based on the required operational duration. Additionally, the drone’s mounting interface type (e.g., gimbal interface, threaded interface) must be compatible with the payload to avoid compatibility issues.

For example, surveying operations require high precision, necessitating payloads with centimeter-level positioning capabilities; long-term inspection operations demand high stability and durability, prioritizing industrial-grade protective (dustproof, waterproof, vibration-resistant) products; and real-time data transmission requires payloads with 4G/5G or image transmission modules to meet remote monitoring needs.

Based on the cost budget, balance payload performance and price while complying with the regulatory requirements of the target market. For instance, some regions have specific restrictions on payload radio frequencies, weight, and dimensions, so compliance risks must be avoided.
