Laser detection and measurement. More widely known as LiDAR (from the same term RADAR). It is a sensing technology that uses laser pointer pulses to measure the distance to the ground. Using this technology can obtain three-dimensional information of the surface shape and surface features. Lidar technology helps professional cartographers and scientists to be more precise. Accurately and flexibly measure and understand natural and artificial environments. Earlier, lidar was limited to government and military applications. With the advancement of technology and the reduction of manufacturing cost of lidar, it has widely penetrated into industrial and commercial fields. The main application areas of lidar technology include: mining, forestry, archaeology, geology, seismology, topographic surveying and power corridor maps. In addition, laser pointer detection and measurement also include applications in the field of civil engineering. Including transportation, city maps and planning. Infrastructure projects and road planning, etc.
At present, civil engineering and planning are the main sources of revenue for laser detection and measurement systems. The lidar market is classified according to product type. Including: airborne lidar, ground lidar, mobile lidar and short-range lidar. However, technological innovation has increased the cost-benefit ratio of terrestrial lidar and mobile lidar systems. In addition, the lidar market can also be classified according to its hardware composition. Inertial navigation system, laser diode. Cameras and MEMS mirrors, etc. Currently, there are no potential substitutes for lidar technology.
In the industry, one way to reduce costs is to eliminate mechanical rotating structures and use semiconductor technology to fundamentally reduce the cost of laser pointer radars. One way is to reduce the number of lidar lines and use multiple low-line lidar combinations. Previously, the domestic manufacturer Sagitar Juchuang demonstrated a multi-rider coupling solution for highways at the 2017 Asian Consumer Electronics Show, including four 16-lane riders, and the price is one-fourth of the 64-line rider. In the future, the cost of vehicle-mounted lidar will be greatly reduced, and large-scale commercial applications are expected. You are the deputy director of the transmission room of State Grid X Gate Electric Power Company You Xiaohua: (Foreign body entanglement) Mainly plastic film, kite string, festive balloons, sunshade nets, green gauze nets, etc.. Foreign bodies from different materials have different melting points Cut directly. (Laser radiation) The high temperature is 300, the power cord is basically aluminum, and the melting point of aluminum is 400 degrees, so there is no harm to the body material.
