Roof Mapping and Visual Inspection

The DJI Matrice 4E is a precise and portable mapping drone. Utilizing the DJI Pilot 2 app to create a straightforward flight plan, inspection teams can swiftly capture comprehensive images of any roof within minutes. This drone delivers accuracy down to the centimeter and reveals details as fine as a millimeter.

Workflow

  1. Data Collection:
    – Perform a quick test flight to verify building height, then plan a 2D map mission about 50-100 (15-30 Meters) feet above the rooftop.
  2. Data Processing:
    – Import to DJI Terra to process a high quality 2D map of the roof and 3D model of the building.
  3. Data Analysis:
    – Highlight problem areas in Terra or third-party processing software, then export issues flagged to an internal ERP software for maintenance team to fix.

Cost-Effective Thermal Roof Inspections

The DJI Matrice 4T enables pilots to capture not only visual images for roof inspections but also thermal imagery that reveals issues invisible to the naked eye. By utilizing both types of imagery, inspection teams can enhance their capability to detect all roofing faults, thereby increasing the accuracy of their inspections.

Workflow

  1. Data Collection:
    – Perform a quick test flight to verify building height, then plan a 2D map mission about 50-75 (15 – 25 meters) feet above the rooftop.
  2. Data Processing:
    – Import the visual imagery to DJI Terra to process a high quality 2D map of the roof and 3D model of the building.
  3. Data Analysis:
    – Highlight problem areas in Terra or third-party processing software from the visual data. Also analyze individual thermal imagery in DJI Thermal Analysis Tools. Then export issues flagged to an internal ERP software for maintenance team to fix.
