According to foreign media reports, the drone car launched by the Finnish Technical Research Center (VTT), Marilyn, has excellent "visual" capabilities in foggy days and even snowy days, enabling uninterrupted navigation in bad weather conditions. . The vehicle can detect pedestrians on the road in foggy weather and avoid traffic accidents.
This is mainly due to the laser radar on the top of the vehicle, which can detect far more wavelengths than the human eye. With the continuous improvement of this technology, the autonomous driving technology will take a big step forward, and the vehicle system will not be stopped by the fog.
Marilyn uses the new 1550 nanowave lidar and its artificial intelligence to enhance the functionality of in-vehicle sensing devices. In addition, the vehicle uses a built-in software module designed to filter the point cloud and evaluate the reliability of the scanning device to achieve the following in-vehicle functions: lifting the lidar in heavy fog and powder snow conditions The "visual" function, the near-infrared spectral band and the vehicle's ability to detect pedestrians.
MatTI KuTIla, project manager for VTT's RobotCar Crew team, said: "Although the Marilyn model has a visual range of only 30 meters in dense fog, the new lidar allows the vehicle to move slowly rather than stop."
The vehicle is also equipped with a conventional type of vehicle radar and laser radar, but the above-mentioned equipment has limited ability to detect non-metallic obstacles, the resolution of the image is not high, and the ability to recognize the shape of the target is weak.
KuTIla emphasizes: "Marilyn has optimized the performance of various types of sensors, using a combination of radar and lidar technology to improve the safety of autonomous vehicles. Although there are still many obstacles in the development process, a large technology has been achieved. progress."
He said: "There is still some distance from the all-weather driving of unmanned vehicles. However, the company is one step closer to realizing the above dream. If the current technological progress is compared to the 42-kilometer marathon, then the company has already reached the end. Going for about 10 kilometers."

GP5800 is highly integrated, medium-capacity GPON OLT for operators, ISPs, enterprises and park applications.The product follows the ITU-T G.984/G.988 technical standard,The communication industry standard of the People's Republic of China "Access Network Technical Requirements - Gigabit Passive Optical Network (GPON)" and China Telecom's GPON equipment technical requirements CTC2.0 standard, can be compatible with G/XG/XGS three modes at the same time. Among them, the asymmetric system (2.5Gbps uplink, 10Gbps downlink) is called XGPON, and the symmetrical system (10Gbps uplink, 10Gbps downlink) is called XGSPON. The product has good openness, strong compatibility, high reliability, complete software functions, and cooperates with the optical network unit (ONU) to provide users with access to various integrated services such as broadband, voice, video, and monitoring. It can be widely used in the construction of access networks such as operator FTTH/C access, VPN, government and enterprise park access, campus network access, etc., to meet the rapidly growing business needs. XG(S)-PON OLT provides higher bandwidth, application scenarios, business configuration and operation and maintenance are fully synchronized and inherited from GPON. GP5810 OLT is only 1U in height, easy to install and maintain, and saves space. The equipment adopts the industry's advanced technology to provide customers with reliable solutions, with efficient bandwidth utilization and Ethernet service support capabilities, helping operators to provide users with reliable service quality. Supporting mixed networking of different types of ONUs can save a lot of costs for operators.
