• JRT Looks Forward To Meeting You At 2019 At The Russian International Hardware Show

  2019 / 10 / 15

  The Russian Hardware Tools Exhibition MITEX has been held since 1998 and is hosted by EUROEXPO. It is a large-scale professional international hardware tools exhibition in Russia. Its influence in Europe is second only to the Cologne Hardware Fair in Germany. It has been held for 21 consecutive times. The scale of the exhibition is large: the exhibition is a large-scale professional international hardware tools exhibition in Russia. There will be companies from all over the world participating in the exhibition. The exhibition will have great business opportunities and links and trading functions. Through the introduction of the product, the exhibitors of various countries can be presented in detail to show the functional characteristics of the products to reach most customers in the entire industry or market. Professionalism: The exhibition is held in Moscow, Russia. The exhibitors include Robert Bosch and Black & Decker, the world's top tool sourcing and distributors, and 3M Russia, a local quality buyer in Russia, as well as special booths for large Chinese companies. They are arranged at the International Pavilion and they are on display. Advantages of the exhibition hall: The Russian Hardware Tools Exhibition was held at the Moscow International Exhibition Center, occupying a large number of exhibition halls throughout the exhibition center. The Ruby Exhibition Center has 9 exhibition halls and multiple function rooms, with a total exhibition area of 150,000 square meters (90,000 square meters indoors and 60,000 square meters outdoor), which can be used for large-scale conferences, seminars and business presentations. And all pavilion architecture and engineering design meet the latest require

• JRT meets you at China International Hardware Show

  2019 / 10 / 10

  China International Hardware Show has been hailed as [the largest tool hardware exhibition in the world", and has gathered thousands of companies from all over the world. Through the exhibition, we can strengthen cooperation with exhibitors from all walks of life in the world, introduce new audience organization channels and means, and increase the organization and promotion of international emerging market audiences while maintaining the advantages of traditional European and American procurement channels. At the same time, strengthen domestic industrial fields and second and third tier cities. The market development efforts to maintain professional and domestic tool buyers and distributors continue to grow. JRT is exhibiting at this exhibition and welcomes your cooperation and exchange. Welcome to China international hardware show in Shanghai, Our booth number: 8.2K115.

• What are the specific applications of lidar in driverless driving?

  2019 / 09 / 29

  1. Positioning Positioning in unmanned driving for ten minutes is important. Only with real-time location information can the system make the next interpretation, decide where to go, and how to get there. There are many ways to position it now. Such as carrier phase difference technology (RTK), but RTK is still subject to signal interference. Especially in some cities, buildings and trees, as well as tunnels and tunnels, its signal is easily interrupted. At the same time, sensors such as cameras are also used to sense the external environment, construct an environmental model, and use the model to determine the location of the vehicle, but its dependence on the environment is relatively strong, such as backlighting or rain and snow, such positioning is prone to failure. Lidar relies on comparing the initial position of the vehicle with the high-precision map information to obtain a precise position. First, sensors such as GPS, IMU, and wheel speed give an initial (probably) position. Secondly, the local point cloud information of the lidar is extracted, and the vector features in the global coordinate system are obtained by combining the initial positions. Finally, the vector features of the previous step are matched with the feature information of the high-precision map to obtain accurate global positioning. Therefore, in terms of positioning, the use of laser radar has an unparalleled advantage in terms of accuracy and stability. 2. Detection and classification of obstacles Lidar does not rely on illumination, its viewing angle is 360 degrees, the calculation is relatively small, and it can be scanned in real time. It is generally used within 100 milliseconds. In the process of scanning, the laser radar first identifies obstacles, knows the position of the obstacle in space, and then classifies according to the existing obstacles. For example, cars and people, we divide th
