VR / AR has also ignited in recent years, and the market prospects are considerable. VR all-in-one, smart glasses and other products have been launched, and AR glasses and AR headsets are also widely used.
In games that use AR headsets, the spatial sensing positioning technology used will use laser pointer radar and many supporting optical sensors. Through SLAM technology (real-time positioning and map construction), they can accurately locate their own three-dimensional space. Location to enhance the real experience in the game.
As the population of large cities continues to grow, the city's traffic also becomes more congested, which requires future traffic to be "smarter". The rapid development of the Internet of Things, sensors, and artificial intelligence has made these a reality. Various technologies such as information technology, sensing technology, and communication technology are widely used in the field of transportation.
Lidar is useful in many places. For example, millimeter-wave radar can accurately detect lane-level and millisecond-level data. This detection is microscopic, and it is also real-time and accurate. It can be used for real-time sensor control of signal lights. , Adaptive control and green wave control are also the basis for the realization of connected vehicle-road collaboration in the future.
In recent years, environmental issues have received widespread attention, and the protection of the marine environment has become a consensus. The marine laser pointer radar, as an advanced marine exploration and monitoring method, has become the mainstream.
Lidar and marine life-related applications are mainly reflected in two aspects: fishery resource surveys and marine ecological environment monitoring. The former often uses blue-green pulsed light as the excitation light source. The identification and extraction of laser echo signals can be used to obtain the fish distribution area and density information, and the fish species can be identified by combining polarization analysis. The latter often uses marine laser fluorescence radar. Through the detection and analysis of the spectral signals such as the fluorescence emitted by the laser-induced target, the species and concentration distribution information of marine plankton and chlorophyll are obtained.
Summary: As a new technology, lidar is a new technology. In addition to the above-mentioned fields, there is still more room to expand in the future, and different scene requirements are not the same. For laser pointer radar, it is a bit obvious, but also has disadvantages, such as The influence of weather factors is large, and the spatial search range is narrow. At present, there is still room for the application of lidar in unmanned driving. As the technology matures, the future market is expected.
