Only a few years ago, the drone detection system also required the cooperation of aircraft, large LIDAR sensors, and crew to complete the image capture. Through the airborne LIDAR sensor and complex software, the LIDAR images are quickly processed in the clouds to provide users with decision-making reference. With the rapid development of LIDAR sensors, this phenomenon has been greatly changed.
It is understood that the field of UAV LIDAR is continuing to maintain rapid growth, especially in the past two years. In a short period of time, the world’s best aircraft LIDAR sensor manufacturers have designed a variety of LIDAR sensor products for small drones.
The output power of these UAV LIDAR sensors is excellent, and as more and more manufacturers enter this field, these sensors are constantly being improved. In the next few years, we will see most of the LIDAR sensors used in the field of unmanned aerial vehicles (UAVs).
The working principle of LIDAR sensor
1. Emit laser pulses;
2. Record the echo signal;
3. Distance measurement (time of flight x speed of light);
4. Retrieve the position and height of the plane;
5. Accurately calculate the echo position.
Features of LIDAR:
High: high scanning speed, high angular resolution;
Convenient: all the way to transmit and all the way to receive, the structure is simple and easy to use;
Low: low power consumption, small size, low weight;
Fine: the accuracy of mapping at the centimeter level;
Province: a batch price of one hundred yuan;
Long: long service life, can work 24 hours a day;
Wide: a wide range of applications.
