The first step is to plan the drone flight. This involves determining the survey area and setting up waypoints or flight paths for the drone to follow. The flight plan ensures that the drone captures sufficient imagery to cover the desired area. Multiple altitudes, flight directions, or camera angles may be considered.

95% of Drone Flights are automated, with human piloted flight making up only a small portion of additional corrective imagery to supplement a mission flight.

Once the flight plan is set, and ground control points are in-place and surveyed with precise coordinates, the drone is deployed to capture aerial imagery.

Equipped with high-resolution cameras, the drone captures overlapping photos from different angles and altitudes as it follows the predetermined flight path. The overlapping images are crucial for accurate photogrammetric processing.

After the drone completes its flight and collects the necessary imagery, the next step is to process the photos using photogrammetry software.

Adam Kasprzak Surveying uses a dedicated supercomputer with network storage to process the large amount of data. The software analyzes the overlapping images and extracts key features and tie points to create a dense point cloud.

The extracted tie points are used to generate a dense point cloud, which is a collection of 3D coordinates representing the surfaces of the objects or terrain in the surveyed area. The point cloud provides a detailed representation of the surveyed area, including the shape and position of objects.

Point Clouds can exceed 200 Million points for larger surveys.

From the point cloud, a surface mesh is created, connecting the points to form a polygonal representation of the objects (DSM) or terrain (DTM). The mesh can then be further refined to produce a more detailed and accurate representation.

Texture mapping is also applied to the mesh by projecting the original drone images onto the surface, adding color and texture to the 3D model.

Depending on the clients requirements, we may proceed to generate a full 3D model from the mesh and texture.

The 3D model represents the area (or structure) of interest in a format that can be visualized, manipulated, and measured.

The Model is georeferenced in UTM coordinate system and geodetic elevations, so can be seamlessly imported into other datasets such as CAD software, GIS platforms, or virtual reality environments.

Depending on clients requirements, we may generate more conventional reporting/plan formats from 3D Model data, by importing this data into AutoCAD for further refinement and annotation. This helps the reader understand the data, and allows for use by third parties without access to complex software.

Our Team provides the deliverables to the client for review. Any revisions the client requires are made to the plan(s) or files.
