During the scanning process, the lidar system will scan various distance points, and based on these points, a 3D image of the surrounding environment can be calculated. Laser scanners use a deflection mirror to deflect the laser pointer, which allows them to achieve a very wide field of view. Most current UAV lidar systems can rotate around an axis and provide 360-degree visibility. And can achieve a very high data rate, more than one million points per second distance.
The working principle of the lidar sensor. Launch laser pulse; record echo signal; distance measurement (time of flight x speed of light); retrieve plane position and altitude; accurately calculate echo position. UAV lidar sensor uses. UAV anti-collision radar sensor. In the lidar sensor, a single device integrates multiple independent components and will generate key ranging data for precise positioning and safe navigation. Lidar sensors have obstacle detection capabilities in a wide field of view, making them ideal for sensing and avoiding solutions. Lidar is the leading technology for car collision avoidance and driverless cars.
Anti-collision technology has now penetrated into the field of consumer drones, including the highly innovative DJI. Ground and surface image lidar sensors. The latest lidar sensors have integrated optical altimeter technology, which can provide accurate distance measurement above ground level while also meeting UAV manufacturers’ requirements for size, weight, and cost. Agriculture and forestry can use lidar to check the growth of plants such as leaves and crops. In addition, the surface area (for example, forest canopy part) can be removed to observe the surface area.
Lidar structure inspection. The best green laser pointer radar sensor has powerful built-in signal processing, large field of view and multi-segment measurement functions, which can generate critical distance data and perform efficient obstacle detection to achieve safe navigation when performing structural inspections. Lidar sensor at night. Lidar sensors, also known as laser scans, can operate in low contrast or dark conditions, even at night. Lidar, multispectral, and taking measurement images are all closely related technologies. In some areas and in some cases, the above three images are required to perform a comprehensive analysis of terrain, vegetation or structure.
