If the road is covered with snow, put a lot of leaves or debris, flooded with muddy water, the driver-a man at least, by indirect signs, can still figure out how to drive. And an unmanned vehicle, without data on road markings and the boundaries of the roadway – no. The new WaveSense technology is designed to address this and even more complex orientation problems where there are no guidelines.
The WaveSense concept is to build an alternative road map using ground scans beneath them. If we drill the soil, we will get a core with a diameter of 4 sq. Cm. And a length of 3 m, with a unique combination of stones, minerals, sand and impurities in it. Modern georadar allows you to do the same, get a personal “fingerprint” of the selected point, but without excavation. If we scan a certain area, we will be able to compile its soil map from position-marks. Then we include in any place the WaveSense georadar, we study the current label, compare it with the database and find out our coordinates.
The greater depth of scanning guarantees the reliability of positioning, even if the upper layers are working, changing the asphalt, bubbling flood, etc., at a depth of 1 m and more all is stable. Tests showed that when driving at speeds of up to 100 km / h, the WaveSense system determines the location on the map with an accuracy of 1-2 cm, despite the presence of interference from snow or debris. That's ready orientation system for drones, as an alternative or addition to existing sets of sensors.
Yes, initially you will have to drive along roads and compile their ground maps. And to take into account that on the steel bridges, over the network of communications of shallow deposition and in other cases the system will fail. But it does not require much energy and collects 8 times less data per unit of time than the camera of the drones – WaveSense installations can be cheaply equipped with any car. Now the authors of the development are looking for ways of the most profitable commercial implementation. It is already clear that this will not be a social and charitable undertaking, like Google Maps, no, it will be a decision for the business, which will affect only the key highways of the planet.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
