2021-06-02
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.
With the development of self-driving technology, car manufacturers and self-driving solution providers pay more and more attention to the importance of lidar, because it can provide high-resolution, accurate and comprehensive information, and its complementarity with other sensors, such as radar, camera and so on. Laser radar plays an increasingly important role in sensor equipment, because of its unique technology to provide reliable, high-efficiency, high-precision three-dimensional data.
Suzhou Lingwei Intelligent Technology Co., Ltd. provides high-quality solid-state lidar sensors, lidar software services and complete lidar application solutions to global customers. The product has 700-line ultra-high resolution, 600 meters long effective detection distance and leading video fusion technology. The product model is rich, there are MEMS 1550nm high-end TitanM1 products, there are flash pure solid-state product TitanS2 series to meet the close detection low-speed exercise collision avoidance, the product is stable and reliable, high precision. Lingwei lidar products are mainly used in automatic driving, vehicle road collaboration, rail transit, three-dimensional mapping, industrial machine vision and other fields.
The main factors that limit the use of lidar are the maturity of the technology, imagination and price. With the breakthrough of lidar technology, the rapid development of the industry and the cross-border application range, lidar will become a low-cost, low-maintenance solution where it is necessary to obtain human or vehicle motion trajectory data. Accurate data can support decision-making in many scenarios.
Laser radar can be described as an important link in the field of automatic driving. The laser beam can accurately measure the relative distance between the edge of the object contour in the field of view and the device. These contour information form a point cloud and draw a 3D environmental map, and the accuracy can reach the centimeter level, thereby improving the measurement accuracy. The application of laser radar in automatic driving includes common functions such as unmanned positioning, exercisable area detection, lane marking line detection, obstacle detection, dynamic object tracking, obstacle classification and recognition.
The application of lidar in smart transportation can improve traffic congestion and safety. Comprehensive data on intersections, roundabouts, roads, highways, parking lots and toll booths can be provided to municipalities and government organizations. This data can help automate decision-making on critical processes, improve road safety, improve traffic and shorten commute times.
Laser radar has a strong ability to resist environmental interference, accurate ranging, long-distance detection, to ensure the safety of railway operation. More and more projects are landing lidar on rail transit, the main scenarios include: for rail intrusion detection, for rail transit obstacle detection, for urban rail transit survey, for shielding door foreign body scanning, for terrain tunnel deformation detection, for platform and train safety protection.
Using three-dimensional lidar measurement is a new method with high efficiency and high precision. Compared with the traditional measurement method, it is fast, low labor intensity and high precision. The large amount of data obtained by lidar scanning and the high density of data points can fully reflect the surface characteristics of the object, so that the volume can be calculated quite accurately, and the surface approximation error that is not easy to solve by conventional measurement methods.
LiDAR is becoming increasingly popular for smart cities, security and other industries. Because lidar can work 24 hours in most weather conditions while significantly reducing erroneous data, without obtaining data through biometrics to minimize user privacy issues. With the continuous breakthrough of software and hardware barriers, more and more industries will pay attention to this point.
