Intelligent Software Platform

4 core modules:

Data Processing

Unifying organization, processing, and preliminary process of drone-collected data. Performing real-time caching and preliminary processing of images, point clouds, and thermal infrared data collected supporting on-site visualization and anomaly monitoring capabilities. This includes real-time mapping, point cloud and image registration, 3D model reconstruction, and Mesh model generation, ensuring that multi-source data is structured, spatially consistent, and facilitates subsequent defects analysis and report generation.

Inspection Algorithm

Generating safe and efficient inspection routes according to spatial structure and operational requirements. Enabling autonomous flight and precise inspection. Adjusting dynamically flight path and avoiding obstacles. Additionally, the inspection algorithm supports segmented inspection task management, allowing inspection tasks to be divided into multiple subtasks based on battery life or data volume, thereby achieving continuous inspection and efficient operations.

Intelligent Defects Detection

Extracting features and performing intelligent recognition on processed 3D models, point clouds, and image data, it achieves automatic positioning, classification, and grading of typical defects such as cracks, leaks, spalling, and corrosion. The system integrates historical inspection data with the current inspection results for model training and optimization, regularly updating the algorithm model to enhance recognition accuracy. The detection results are spatially correlated with 3D models and point cloud data, supporting visual display and precise positioning, thereby providing an intuitive basis for subsequent operation and maintenance management.

Auto Report Generation

Integrating and organizing inspection data, 3D models, and analysis outcomes in a unified and structured manner, automatically generating standardized inspection reports. Supporting templates and one-click generation, enabling standardized inspection reports. Enhancing the efficiency of inspection results and reliable data support for defects tracking, comparative analysis, and decision-making.
