The biggest advantage of laser radar, four systems, eight indicators

The distance is determined by measuring the time difference and phase difference of the laser signal, the angle is measured by horizontal rotation scanning, and a two-dimensional polar coordinate system is established according to these two parameters, and then the height information in three dimensions is obtained by obtaining different pitch angle signals.

There are many lidar parameters, what should we pay attention?

Angular resolution is the ability of the scanner to resolve the target. The smaller the angular resolution, the smaller the target can be resolved, and the finer the measured point cloud data. Generally, the angle measurement accuracy of the obstacle avoidance laser sensor is only about 0.1 °, while the angle resolution of the mapping laser sensor is generally 0.001 ° or even lower.

Lidar opens up new markets: from autonomous driving to vehicle-road collaboration

In 2020, new infrastructure has become an absolute hot spot for investment, entrepreneurship and society in China. As an indispensable part of the new infrastructure, intelligent transportation promotes each other with 5G base station construction, big data center and artificial intelligence. Road coordination is the foundation of intelligent transportation and smart city, which is closely related to people's life and attracts more people's attention.

Application of UAV in Lidar

Unmanned aerial vehicles include logistics unmanned aerial vehicles, surveying and mapping unmanned aerial vehicles and formation performance unmanned aerial vehicles. In the operation process, due to the complex and changeable environment of unmanned aerial vehicles and the difficulty of control, technology is needed to provide real-time and stable ranging and altitude setting flight functions for unmanned aerial vehicles, so that they can safely and freely complete flight work in changeable environment. Height setting is very important.

Application Scenarios of High Resolution Lidar

Laser radar is widely used in urban planning, road construction, aerospace and national defense because of its excellent mapping and detection capabilities. The earliest use of lidar dates back to the 1970 s, when NASA applied it to space exploration. No-load lidar only became popular in the 1980 s and 1990 s to generate accurate topographic maps.

Application of Lidar Technology in Building Facade Vectorization

With the development of economic construction, the state is vigorously promoting the transformation of urban buildings, supporting affordable housing projects, and supporting the infrastructure construction of urban old community transformation and shantytown transformation. Obtaining an accurate building elevation can ensure the consistency of the architectural transformation style of the whole region, which is of great significance to the construction, transformation and facade decoration of the building.

What is the solid-state lidar technology route?

MEMS (Micro Electro Mechanical Systems) is the abbreviation for MEMS and is the name used in the United States. It refers to the miniaturization and electronic design of mechanical mechanisms. Previously bulky mechanical structures could be integrated onto silicon-based chips through microelectronics technology, allowing for large-scale production. One dimensional vertical scanning can be achieved through MEMS micromirrors. The other light sources are fiber lasers, mainly due to the low repetition rate and high average repetition rate of 905nm tubes.
