During RGB camera imaging, the drone takes multiple overlapping photographs of a given area from different angles. The drone's high-resolution camera continuously records images along the flight path, assigning GPS coordinates to the location where each image was taken.
During processing, common points are identified from the photographs taken along the pre-parameterized route, and these are stitched together to create a three-dimensional model of the area. The final products of this process are the digital surface model, the digital terrain model, and the orthomosaic. This method allows for detailed surveys of buildings, agricultural areas, and other objects, ensuring high accuracy and detail.
