Historical story unmanned aerial vehicle-through myth

Nowadays, in the streets of big cities, you can often hear the buzzing sound, and there is a quadrotor flying overhead. This is usually the more and more small drones that have caused a lot of trouble. In addition to traditional TV stations, film photography and more and more advertisements, small drones have been used for weddings. From time to time, they also come into everyone's sight in controversial ways such as sending rings and entering the White House, or various teams announce their ideas and products. So, what exactly is a small drone?

In the movie, the adventurers released a small flying machine, which used multiple lasers to scan the cave in all directions, and at the same time explored the open unknown area to reconstruct the structure of the whole cave in real time. This technology, which I have mentioned in many articles, is called simultaneity localization and mapping technology, or SLAM for short, and it is one of the core technologies of UAV today. He is used in the videos of various drones that are often screened in the circle of friends. The technical details and current progress will be introduced in detail in later articles.

In fact, SLAM is not far away from us. For example, the sweeping robot on Taobao has applied this technology. The significance of SLAM is very far-reaching. For example, on the anniversary of the Wenchuan earthquake a few days ago, many children in the author's circle of friends expressed their hope that the next earthquake (after all, the earthquake is inevitable) will not only be brave PLA armed police soldiers, but also drones and unmanned vehicles. Scanning the disaster area, looking for the lost people and evaluating the disaster situation are all inseparable from SLAM technology.
