On Dec. 28th, 2021, the 4th Jiangsu Artificial Intelligence Conference (JSAI2021) was successfully held in Nanjing. “Road Test Assessment System based on Machine Vision and HD Map” (hereinafter referred to as “Smart Road Test Assessment System”) of Duolun Technoligy was honored with “2021 Jiangsu Award of AI-based Innovative Products”.

According to Notice on Organizing Application Work of 2021 Jiangsu AI-based Innovative Products and Solutions (SGXCX No. 403(2021)) by the Industry and Information Technology Department of Jiangsu, this evaluation is aimed to promote deep integration of artificial intelligence and real economy. Through a series of processes including application by enterprises, recommendation by cities, formal examination, review by experts, review by the Department and announcement of the shortlist, “Smart Road Test Assessment System” of Duolun Technology was finally granted “2021 Jiangsu Award of AI-based Innovative Products”.

Equipped with cm-level RTK differential positioning chip, “Smart Road Test Assessment System” can prepare road mapping and 2D virtual model of the vehicle in advance. During driver training and testing, RTK positioning equipment on top of the vehicle can give high-precision positioning of the vehicle model in real time via affine transformation algorithm. Also, the system employs spatial data analysis and mining algorithm to judge geometric relations between the vehicle model and site model, and analyze and extract real-time events as much as possible to get the driver’s basic characteristic data of driving behavior. By inputting advanced characteristic data obtained from mathematical models into customized rules engines, it can draw a conclusion regarding a driver’s driving behavior characteristics.

Underpinned by video vision and digital modeling, Duolun Technology improves GPS signal positioning and expands the application scope of digital modeling by using video image recognition technology instead of a differential GPS positioning system. Thanks to this new technology, the system can precisely playback the test, identify operational problems during driving, and provide replaying evidence for disputed test results. Now the system is widely applied in automatic evaluation system of the driver's license test Subject 3 in various cities.

At present, the products of Duolun Technology are protected by more than 70 pieces of various intellectual property rights, with major honors including “First Prize of Science and Technology” awarded by Jiangsu Provincial Comprehensive Transportation Society, “Nanjing Innovative Products”, Jiangsu Province “Tengyun Jiashu” Award for Excellent Products, “Key New Technologies and Products to be Promoted in Jiangsu Province” and etc., thus demonstrating the product superiority of Duolun Technology.

The “Smart Road Test Assessment System”, which is independently developed by Duolun Technology, reduces manual supervision in road testing and standardizes the criteria of driver testing. It not only minimizes subjective factors in evaluation, realizing a fair, just and open test, but also achieves a remote supervision and intelligent evaluation, greatly improving test efficiency. It makes an important contribution to safe driving and road safety and laying a solid foundation for China’s development of road safety.
