Recently, as evaluated and announced by Nanjing Municipal Bureau of Industry and Information Technology, the “Road Test Judging System Based on the Integration of Machine Vision and High-Precision Map” (hereinafter referred to as “Intelligent Test System for Subject Three”) independently researched and developed by Duolun Technology has been awarded the honorary title of “2021 Nanjing Innovative Product”.

The selection aimed to accelerate the promotion and industrialization of innovative products and create “Created in Nanjing” series of products and brands. It was developed in the areas of eight industry chains, including software and information services, artificial intelligence, intelligent manufacturing equipment, integrated circuits, smart grids, rail transportation, and new energy vehicles in accordance with the Administrative Measures for Evaluation of Innovative Products in Nanjing (on Trial) (NCXCPTGB[2020] No.1). The list was finally publicized after the expert review, oral defense of project and on-site evaluation.

The Intelligent Test System for Subject Three independently developed by Dolan Technology can map the 2D virtual models of sites and vehicles in advance based on centimeter-level RTK differential positioning. When a vehicle is used in testing and training, the RTK positioning equipment installed on the roof of the vehicle, combined with affine transformation algorithms, allows the system to precisely locate the vehicle model in a virtual scene in real time; the spatial data analysis and mining algorithm enable the system to define the geometric relationship between the vehicle model and the site model, and analyze and extract real-time events, thus acquiring the driver’s basic behavior features; and the advanced feature data from mathematical modeling and tailored rule engines make it possible for the system to reach conclusions about the driver’s driving behavior features.

At the same time, the product can use machine vision technology to obtain the information of surrounding vehicles, pedestrians and road environment, and deeply integrate with the high-precision map, so as to obtain the information on the vehicle’s perception of the surrounding environment. The nearly ten patented technologies used in the product demonstrate Duolun Technology’s corporate strength in independent research and development and industrialized application.

At present, the driving behavior detection method based on high-precision positioning and digital modeling technology has been widely applied to the automatic judging system for drivers’ test and the intelligent coaching system of driver training robots. It can significantly improve the automatic judging rate of computers, and effectively solve the current problems of low automatic judging rate and irregular manual judging in the test of subject three for motor vehicle drivers. At the same time, it can provide powerful support for the analysis of drivers’ driving behaviors, and the intelligent assessment of drivers’ driving skills and safety awareness.

Technology drives innovation, and innovation drives development. In the future, Duolun Technology will continue to research, develop and iterate its products, so as to help achieve a fair and just test for drivers, and improve the efficiency of the test while contributing its technological power to improving drivers’ safety awareness and building the road environment for safe driving and travel.
