Meaning
Building inspection drones are unmanned aerial vehicle systems equipped with high-definition pan tilt cameras, laser radars, infrared thermal imagers, and other equipment, specifically designed for building appearance inspection, structural disease screening, and safety hazard monitoring.
Mainly used for non-contact aerial inspection of building facades, roofs, high-altitude components, etc., replacing manual high-altitude dangerous operations, widely used in building safety assessment, engineering acceptance, old house inspection and other scenarios.
Basic principles
Principles of Flight and Positioning
Using multi rotor unmanned aerial vehicles as a platform, vertical takeoff and landing, fixed-point hovering, and close range flying can be achieved, combined with satellite positioning and visual positioning to ensure stable high-altitude operations.
Principles of Image and Data Acquisition
Capture appearance defects such as cracks, damages, and detachment through high-definition visible light cameras; Using infrared thermal imaging to detect leakage, hollowing, and insulation defects; Lidar can measure deformation and obtain three-dimensional structural data.
Principles of Data Transmission and Analysis
Real time transmission of images to the ground, taking photos and videos of abnormal areas, locating and marking them, and later completing structural safety analysis and disease identification through image comparison and 3D modeling.
Main features
- The core function is to inspect the appearance and safety of building structures
- Can fly close to buildings at close range, with high hovering accuracy
- Replace high-risk manual inspections such as high-altitude hanging baskets and spider men
- High detection efficiency, comprehensive coverage, and no dead corners or blind spots
- Can achieve multi-mode detection of visible light and infrared
- Data can be archived for easy disease tracking and acceptance
