Image quality

High-resolution aerial imagery

Get large coverage, high image quality and accuracy all at once

Thanks to its high payload capacity, the WingtraOne mapping drone can carry a wide range of high-end sensors, including the Sony RX1R II (42MP) and the RGB61 (61MP).

These sensors capture incredibly detailed, high-resolution images.

The high resolution enables the creation of more precise orthomosaic maps and allows for mapping larger areas with the same level of accuracy.

20 MP vs. 42 MP sensor

Due to the limited payload weight they can carry, multicopters and standard fixed-wing drones can only be equipped with 20 MP sensors.

Thanks to its VTOL capability, the WingtraOne can take a 42 or 61 MP full-frame sensor on board.

The resulting high resolution images pay off with a lower GSD and striking resolution lines.

Higher resolution means better accuracy

During post processing, the coordinates are defined for each pixel on the map. And the ground sample distance (GSD) is also defined by how much ground is captured by a single pixel. Thus, the more pixels there are, the more accurate the final map can be. For example, if you fly with a GSD of 3 cm (1.2 in) /px , this is also the best possible absolute accuracy. 

The WingtraOne mapping drone and the 42 MP Sony RX1RII sets a new benchmark by offering images of an unprecedented pixel density resulting in a 0.7 cm/px (0.3 in/px) GSD. This enables well-tested absolute accuracy down to 1 cm (0.4 in).

The ground sample distance (GSD) is the distance between the centers of two neighboring pixels. For example, in an image with a 1 cm/px GSD, neighboring pixels’ image locations are only 1 cm apart on the ground. Therefore, the more pixels in the images there are, the more detailed the map and the more accurate the resulting measurements can be. In addition, since each pixel contains its own geospatial data, the higher the image resolution, the lower the absolute accuracy can be.

Higher resolution means broader coverage at the same GSD

With a 42 MP or 61MP resolution full-frame sensor it is possible to fly higher and achieve the same GSD accuracy while covering more area at the same time and reducing operation costs for the capture of aerial imagery.

Higher resolution means better map reconstruction

When using a drone with a lower resolution sensor, it happens very often that map generation fails. The high resolution and low distorion lens of the the Sony RX1R II and RGB61 sensor allow much more reliable reconstruction of orthomosaic maps and 3D models. This level of detail proves especially valuable in cases of grass fields, sand, forests or similar homogeneous patterns.

From our customers

The main advantage with the WingtraOne was the high quality images from the camera. The Sony RX1RII camera with 35 mm lens makes it possible to cover the area efficiently at a high altitude of 390 m.
