15 SIRIUS UAS Simple to use Operation: When working with the UAS on a daily basis the operation of the system should be as simple as possible. After quick assembly of the SIRIUS UAS the operator chooses his area of interest and the desired Ground Sampling Distance (GSD). The flight planning software MAVinci Desktop automatically creates an individual flight plan. The flight plan can not only be calculated quickly in the field but also in the office before the mission starts. In addition MAVinci Desktop provides the possibility to change the flight plan even when the UAV is currently in the air and flying. One click in MAVinci Desktop transfers the flight plan wirelessly to the UAV. For automatic take off, the operator launches the UAV by throwing it into the air without any additional catapult or bungee rope. The hand launch is easy and comfortable. During the completely automatic flight the UAV follows the predefined flight plan. When the mission is finished the landing is carried out: The UAV is able to land fully automatically or if obstacles or the small size of the area prohibit automatic landing the operator can easily land manually with autopilot assistance. The UAV is stabilized by the autopilot and manually controlled by simple up/down, left/right commands. Once you tried this feature you will never want to miss it again! In addition a full manual landing is also possible. After landing the photo log data (GPS positions and time stamps of the images etc.) will be copied from the UAV to MAVinci desktop wirelessly. The systems has no disturbing cables in the field. Transport: The SIRIUS UAS is a light weight system with small pack size. All equipment fits into one single box with a total weight of about 20 kg. The transport box is made of robust aluminium and especially designed for permanent commercial use. It protects the UAS perfectly during transport and is resistant to corrosion, weather and temperature influcences. 16

16 SIRIUS UAS Safety The safety of the system is one of our main objectives. Therefore we implemented several features that will protect you and the people around you: Electric Engine Safety Button Before launching the UAS the electric engine is locked and cannot start by accident. A special release button on the side of the UAV body enables the operator only and no other person to release the electric engine and activate it shortly before launching. After landing a push on the safety button also locks the engine and secures the system. Autopilot assisted manual control Automatic take off, flight and landing of a UAS is an innovative and very useful feature. When using the UAS in the field unpredictable things such as a rescue helicopter that is passing your flight area will happen. It is therefore very important that the operator is able to interrupt the automatic flight of the UAV at any time to steer the UAV manually. Our autopilot assisted manual control mode enables the operator to control the UAV assisted by the autopilot. In this mode the UAV is stabilized by the autopilot. The controller steers the UAV with simple up/ down, left/right commands. The autopilot assisted control is very easy to learn within minutes. The UAV in addition always stays in the visual range of sight in this control mode. In some countries the operation of UAS without the option of manual control is not allowed. The assisted manual control enables you to legally operate your UAS in these countries without learning full manual UAV control. Security Features and Emergency Actions To prevent emergencies the UAS has several security features. Multiple radio links and an additional manual backup control link that is independent of the autopilot minimize the risk of radio link failure. The UAS has two wireless data links for up to 40 km line-of-sight range (actual frequency and range depends on your local regulations) and an additional RC transmitter with 2.4 GHz ISM link for manual backup control with up to 3 km range. Even if the UAV is outside of radio link range it continues to follow the flight plan and finishes its mission because all important data and the flight plan are stored on board. The flight planning software MAVinci Desktop shows status data of the UAV during the flight. For example RC link state, GPS state, position of the UAV and battery levels. In addition the altitude of automatic operation can be limited (e.g. to 150 m). To minimize the damage to the UAS and increase the safety of the system the UAS performs special emergency actions if necessary: In case of engine failure (e.g. due to low battery level): The autopilot still stabilizes the UAV attitude to prevent a crash and descents. The operator can send a return home command. Then the UAV will come back to the ground station. If GPS signal is lost the UAV circles in waiting position. 18

17 SIRIUS UAS High Quality Results Advanced Panasonic GX1 Camera Any UAV payload should be as small and light as possible but deliver high quality data at the same time. For these reasons we integrated the Panasonic GX1 camera into our UAS. It is small and lightweight compared to a digital single lens reflex (DSLR) camera and has a 16-megapixel Live MOS sensor. The sensor s area is only 30 40% smaller than APS-C sensors used in most other DSLRs, and about 9 times larger than the 1/2.5 sensors typically used in compact digital cameras. Together with the panasonic GX1 camera we use a Panasonic 20mm f/1.7 Lens. The focal length of the lens is fixed to increase the quality of the post processing results. Optionally we offer the calibration of the camera with the lens. Quality Check on the field Some of the jobs you will do with the UAV might be in remote areas and a long journey was necessary to reach your area of interest. With our quality check function you can verify the quality of the dataset you acquired directly on the field within minutes. This function checks the overlap of the single images and indicates sufficient overlap with green color. Accuracy During calculation of 3D models out of image data a minimization algorithm is used to determine the best mathematical solution for calculation of the 3d model. What is usually referred to as accuracy of the 3D model is the average standard deviation of all tie points in the solution that is found by this algorithm. This standard deviation is in the order of 2 times the ground sampling distance (gsd) in x and y direction and 3 times gsd in altitude of the 3d model (The gsd can be up to 2 cm if flying very low). For further information about quality and results of the data produced with our system please see pages High resolution geo information products The area that can be covered during one flight with SIRIUS I depends on the GSD. Due to the low flight altitude high resolutions of 2-10 cm GSD are typically achieved. In one 40 min flight one can cover: Area coverable in one flight with pseudo orthophoto (10% overlap in flight and side direction) at 2 cm GSD and light wind: 170 ha at 5 cm GSD and light wind: 360 ha at 10 cm GSD and light wind: 670 ha Area coverable in one flight with DEM/true orthophoto (75-85% overlap in flight and 65% in side direction) at 2 cm GSD and light wind: 55 ha at 5 cm GSD and light wind: 120 ha at 10 cm GSD and light wind: 200 ha Please note: The actual imaged area is larger. The values given refer to the area that can be processed at full (3D) accuracy, rather than the area that was imaged. The border of the area where reduced (3D) quality is to be expected is excluded from the given value. Value given is for optimal (3D) quality with side overlap metioned above. Larger areas can be covered with compromises in (3D) quality. Reserve for low wind is included in the calculation. 21

18 MAVinci Desktop Case Study: Infrastructure Modeling Using MAVinci UAS Data Detailed topography and visualization of noise barriers in Lummen, Belgium Planning infrastructure projects requires a vast amount of preparation that almost inevitably starts with an accurate topographic survey. This allows construction engineers to calculate terrain leveling and ensure an exact fit of newly built into existing infrastructures. On the other hand, full surveys can be laborious making them costly and time consuming. The Flemish Roads and Traffic Agency, upon planning the construction of noise barriers along the E314 and E313 highways in Lummen (Belgium), chose a smart alternative. A full topographic survey was replaced by a limited survey supplemented with a high resolution orthophoto and a high density elevation model, derived from UAS data acquired by MAVinci and processed by GeoID. The result: much richer information and on top, a high quality 3D visualization. In a few hours time, three different UAS flights were made in three designated zones along both highways, covering over 170 hectares. Each flight resulted in 400 to 700 photos. Photogrammetry specialists at GeoID processed these photos into high resolution true-orthophoto s and elevation models, with a 4 cm pixel size. Since high accuracy in this project is critical, in each zone at least 10 well marked ground control points (GCP s) were measured to exactly position (georeference) the model. Assessing accuracy In error assessment, the most widely applied statistic is the calibration error. Calibration error expresses for each GCP the difference between reference coordinate (from a total station or RTK GPS) and its corresponding coordinate from the orthophoto and elevation models. Unfortunately, this is no reliable measure of the accuracy of the entire model as reported calibration errors inevitably underestimate true errors. The reason is that the same GCP s are also used to georeference the model so that these points are no longer independent validation points. An elegant solution to this problem is a statistic named cross-validation. In cross-validation, a terrain model is calibrated by leaving out one GCP that is used as an independent validation point. This procedure is iterated many times, each time leaving out another GCP. The resulting cross-validation error is a much more reliable measure of accuracy. Let s look at an example. In the southern zone of the project area, calibration errors were 4 cm for planimetry (X and Y) and 5 cm for altimetry (Z). This is what would normally be reported by automated image processing algorithms. The cross-validation errors were 6 cm for planimetry and 13 cm for altimetry. How reliable is this? For the same zone, an independent set of over validation points, distributed along the highway, could be obtained from a related project. This allowed a detailed validation experiment, producing a validation error in Z of 11 cm. This is only slightly smaller than the reported cross-validation error but substantially larger than the calibration error. For other zones, comparable results were obtained. This demonstrates the usefulness of cross-validation as a reliable statistic for accuracy assessment. Visualization With an ever growing concern for public participation, no large infrastructure project can go without effective and open communication. And communication and visualization go hand in hand. Instead of reverting to standard communication strategies such as sketches, stills and pre-rendered animations, the Flemish Roads and Traffic agency chose to openly communicate this project using an interactive 3D visualization. The orthophoto and elevation models of the three sites were combined into a 3D environ- 22

19 ment using GeoID Virtual Surveyor Tools within the powerful Skyline TerraExplorer software. Models of the planned noise barriers as well road furniture (guard rails, lights) were imported and correctly positioned along the highways. In the resulting 3D environment, users can choose to freely navigate to any viewing point or fly or drive along predefined routes. Figure 1. Shaded relief of one project zone. Crossvalidation errors in altimetry are grey disks, with errors in centimeters, validation points are black dots, confidence bounds as a blue. Figure 2.
