Dronemetrex Accomplishes Mapping Project, Contributes to a Cleaner Australia

Adelaide-based DroneMetrex has successfully performed another project using its premier mapping system TopoDrone-100. This time the Client was one of the key players in recycling and waste management industry of Australia and DroneMetrex managed to make a humble contribution to the cleaner environment of the country.
The mapping project helped the Client solve lots of important issues and the TopoDrone-100 accuracy proved to be paramount in this respect. The Client is licensed by the Environment Protection Authority (EPA) to build the waste mounds to an absolute height of 26m above sea level (ASL). After several months, the compaction of the waste, due to it’s own weight and top-soil, reduced the height of these large waste mounds. This provided the opportunity for more waste to be added onto the same mound. Therefore, it became vitally important that the accurate height of the mounds is regularly monitored as this would ensure that the mounds are always under the absolute ASL height, which is a legal obligation. At the same time, monitoring the amount of waste mound compaction allowed the Client to financially benefit by adding additional waste to the same mound.
Secondly, the project also involved the mapping of the whole area owned by the Client, in order to be used as the base mapping for future planned expansion of the waste processing requirements. Importantly, the mapping needed to be accurate to compare Ownership with Occupation (cadastral boundary which is ownership versus the fencing on the presumed boundary which is occupation).
A high accurate photogrammetric mapping system TopoDrone-100 reliably mapped a waste recycling site covering the area of 4sq.km and captured 2,5cm GSD aerial imagery with 25mm absolute accuracy. The company specialists launched and landed from open paddocks, and the whole flight sortie took 60 min of flight. They measured by kinematic GPS survey 10 detailed features to use as the GCP’s for the photogrammetric processing. The data processing took 2 hours.
Tom Tadrowski, Executive Director of DroneMetrex, says: “Because the TopoDrone-100 uses our unique (patent-pending) Gyro-stabilised Active Mount (DMX-GAM), which houses a 24Mp digital camera with Zeiss lens, full-framed sensor and leaf-shutter, the imagery captured is "photogrammetry-ready". To explain; each image is near-nadir, no crab, and without the random geometric errors of all other digital camera systems. We then process with our own software in the pre-processing stage correcting for the known systematic errors. Once we have the photogrammetric aerial triangulation, and then the generation of the dense point-cloud, we treat this as our base product which allows us to further generate the DTM, DSM, digital orthophoto mosaic, contours and profiles. Because our TopoDrone data is proper photogrammetric data, we are able to use the stereo image pairs for accurate human "heads-up" 3D digitising of line features if required. The unique mapping accuracies of the TopoDrone enable us to confidently provide photogrammetric accurate data.”

This provides alternative solutions to costly data acquired from aircraft or similar airborne and/or vehicular platforms over areas that are not economically justified to be captured by such large aircraft, or may be difficult and/or dangerous for “manned” aircrafts or vehicles or ground survey teams. With the TopoDrones the company produces truly accurate mapping data – 25mm accuracy in height – reliably, repeatedly, accurately.
 

DroneMetrex Maps a Railway With Unsurpassed Accuracy From Its TopoDrone-100

August 15, 2013 – DroneMetrex has successfully performed a high-precision railway mapping project in Australia. The company’s in-house developed TopoDrone-100 flew and reliably mapped 0,5 km on each of the four sides of the approach to the crossing intersection of the railway and the bitumen road with the unsurpassed accuracy: the company’s UAV captured 2,5cm GSD aerial imagery with 25mm absolute accuracy in height.

DRONEMETREX MAPS A RAILWAY WITH UNSURPASSED ACCURACY FROM ITS TOPODRONE-100.


DroneMetrex has successfully performed a high-precision railway mapping project in Australia. The company’s in-house developed TopoDrone-100 flew and reliably mapped 0,5 km on each of the four sides of the approach to the crossing intersection of the railway and the bitumen road with the unsurpassed accuracy: the company’s UAV captured 2,5cm GSD aerial imagery with 25mm absolute accuracy in height. So far, no other manufacturer of drones has claimed such an accuracy, neither relative, nor absolute. DroneMetrex was able to achieve great results due to the fact that its TopoDrone-100 is a true photogrammetric mapping system which addresses geometric errors (tip, tilt, yaw, forward and lateral motion, blur) from the start and eliminates them right at the point of capturing the data.

The mapping project was aimed, in the first instance, at creating 3D “real world” for obscurity analysis when approaching an intersection from a train driver’s perspective, and from a vehicle driver’s perspective. Secondly, high accurate mapping was performed for future civil works involving repair as well as upgrading of the existing railway.

Traditionally such projects presuppose aerial photography, LiDAR and corridor mapping from large manned aircrafts, which was not economically justified in this particular case, since the project area was quite small. At the same time, conventional ground surveying techniques were either inapplicable, as it would mean temporarily closure of the railway in order to observe all health and safety standards.

Tom Tadrowski, Executive Director of DroneMetrex, commented in this respect: “The whole process of data capture took us only 2 hours and our TopoDrone-100 let us easily meet all the client’s requirements. The launches and landings happened from the nearby field, therefore no interference with rail movements, no disturbance for road traffic ever occurred – in fact, they didn’t even know we were there! As you can see, aerial mapping no longer needs to be time-consuming, no longer expensive and certainly should be readily available.†We have dramatically increased the productivity, data reliability and reduced the costs.”

The aerial photography was performed with 70% forward and 40% side overlap. Based on the captured data, DroneMetrex’ photogrammetrists produced very dense 3D point cloud, digital orthophotos and DTMs, as well as they performed 3D line mapping via photogrammetric 3D “heads-up” digitising. Mirahmad Chabok, Development Manager, said: “Because the photogrammetry from our accurate TopoDrones allows, we can match and produce a point cloud density of 1600 points per sq metre, i.e. 1 point per pixel!”

UAV Drones Collecting Data and playing James Bond Music

There’s no arguing that the topic of drones (also known as unmanned aerial vehicles  or UAV)  are a huge topic, particularly when it comes to data collection. Naturally, UAVs are also of concern when it comes to privacy. But you gotta admit that any technology that you can mashup to play a them from a James Bond movie has to be considered way cool! Here’s just another use for those drones you have locked in up in storage until the government lets you take them outside to fly a mission!  Thanks to the U of Pennsylvania engineers for this


NEW VIDEO GAME AIMS TO CREATE REALISTIC COMBAT DRONE SIMULATOR USING GOOGLE EARTH

Austin, TX, October 9, 2012 – A new game in development promises to leverage the technology of Google Earth to offer players the largest explorable map in video game history.  "Geoception", by Earthling Technology, allows players to command and control UAVs and other combat drones in a realistic manner, anywhere in the world.

Tactical scenarios and missions can be dynamically generated at any location on the globe, providing challenging targets such as armed personnel, moving vehicles, and rooftop sentry guns.  Successful completion of missions earns rewards and medals, with the ultimate goal being to establish total global security.

All game actors can be easily replaced with virtually any Sketchup/3D models of the player’s choosing, allowing a totally customizable gaming experience.  You can replace the drones with dragons, or the soldiers with Smurfs.  It’s your world, and your game.  Craft your own actor models in Sketchup, or choose from a wide selection of free models in 3DWarehouse – even zombies!

And with Google continuously improving the quality of their digital globe behind the scenes, the player is guaranteed an ever-improving game map and environment.  This new concept of "reality gaming" – i.e, gaming in a realistic model of the actual world we live in – truly has the potential to revolutionize the way people think of video games.
