AI Technical Summary

Technical Problem

Existing methods for manually cleaning multispectral cameras are insufficient in terms of timeliness, standardization, and efficiency in field operations. They are also unable to effectively solve the problems of dust adhesion and condensation, which affect the accuracy of surveying data and operational efficiency.

Method used

Design a lidar and multispectral integrated mapping drone, employing an intermittent drive mechanism and an intermittent sealing mechanism. By using an intermittent air blowing pipe to align with the multispectral camera, a gentle and stable airflow is achieved to clean the lens, avoiding lens damage and condensation residue.

Benefits of technology

It achieves efficient and thorough lens cleaning, improves defogging and dust removal efficiency, extends camera lifespan, reduces equipment maintenance costs, adapts to the needs of unmanned field operations, and ensures the stability and accuracy of surveying and mapping operations.
