The lidar-based technology used to create the world’s first laser maps a region with an accuracy of one meter.
It is the first time the technology has been used for such a purpose, and the team of scientists and engineers is using it to create a new type of mapping system that uses the lasers to detect and track vehicles, according to a report in the online journal Nature.
The researchers, led by Nanyang Technological University’s (NTU) Technology Development Center, are developing the new system using a laser that can track and measure objects, not just objects in the sky.
Instead of the traditional lidars, the laser system relies on a combination of light and sound to track objects.
Its use will allow scientists to develop more accurate maps of large areas, such as urban areas, the report said.
This new technology has the potential to improve the accuracy of mapping in urban areas by using the same lasers to track buildings and vehicles, said NTU researcher Cheng Zhang, who is part of the research team.
“In the future, we could see a new generation of maps of urban areas,” Zhang said.
“By using the lidar, we can make the mapping more precise and better.”
A lot of lidar research is focused on the Earth’s surface.
It can detect subtle changes in brightness, or the amount of light reflected from an object.
Lidars also work well in very low-light environments, where objects are invisible to the naked eye, the team reported.
Using the new technology, the researchers are also working on a system that will detect small changes in the light that is reflected off the surface of the Earth.
That could be useful for remote sensing applications.
In a demonstration of the new lidar system, researchers measured the distance between a pair of lasers and a set of buildings in downtown Singapore.
They found that the laser beam, which is used to produce the maps, was capable of mapping only about 50 centimeters in a vertical plane.
But the team used sound to detect objects in a 360-degree, 3-D map, Zhang said in the report.
The team found that this laser, while detecting objects in low-resolution, provided a good map.
Scientists are developing more precise maps of the same areas.
Because of its unique ability to detect subtle variations in brightness and the amount reflected, the technology is ideal for detecting changes in human activity, Zhang and his team noted in the Nature paper.
Previous research has shown that lidar devices can also detect changes in temperature, which helps the scientists track people and objects.
The team of researchers said their work could help other researchers, especially in areas that are hard to track, such an airport or highway.
If lidar can be used to map the surface, the mapping technology could help better predict earthquakes and tsunamis, which could help reduce the risks of a major disaster.
Although the technology works well in low light, it could also be used for remote-sensing applications, Zhang noted in his paper.
“Using this method, we will be able to use lidar to detect small fluctuations in brightness,” he said.
