Description

Technical Field

[0001] This invention relates to the fields of automated driving test evaluation, driving training, electronic map application and image recognition technology, specifically to a driving test and training system and method based on general electronic maps and visual judgment. Background Technology

[0002] Currently, most motor vehicle driving test systems use a combination of high-precision positioning equipment and dedicated electronic mapping maps to achieve vehicle location and test evaluation. These systems have the following problems: High-precision mapping of the examination venue is required, which involves large upfront investment, long construction period, and high maintenance costs. Specialized equipment and maps cannot be reused on ordinary roads or training grounds; Candidates are unable to use the same automated evaluation system as in the examination room during their daily training, resulting in a disconnect between training and examination.

[0003] Therefore, it is of great significance to develop a driver's test and training system that does not require high-precision maps, is low in cost, and can be automatically evaluated directly on general-purpose equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a driver's license test and training system and method based on general electronic maps and visual judgment, solving the problems of high cost, reliance on high-precision maps, and inability to popularize training in traditional driver's license test systems.

[0005] 1. System Composition A driver's license test and training system based on general electronic maps and visual judgment includes: Image acquisition module It includes vehicle-mounted cameras and fixed site cameras, used to collect images of vehicle posture, wheel position, road markings, edge lines, traffic signs and traffic lights in real time.

[0006] General electronic map module Load and run ordinary civilian navigation electronic maps, without the need for high-precision survey maps, to display vehicle location and driving trajectory.

[0007] Visual judgment module The collected images are analyzed to identify demerit points in driving tests or training, including crossing lines, the vehicle body going out of bounds, improper parking, and incorrect use of lights.

[0008] Display terminal It is used for devices such as mobile phones, tablets, or in-vehicle navigation systems to simultaneously display general electronic maps, real-time images, vehicle locations, demerit points, and evaluation results.

[0009] Control module It connects to the image acquisition module, the general electronic map module, the visual judgment module, and the display terminal respectively to realize data processing, logic control, and automatic scoring.

[0010] 2. Working Methods A driving test and training method based on general electronic maps and visual judgment includes the following steps: Real-time images of vehicles and road environment are collected using vehicle-mounted cameras and site cameras; Use and load ordinary civilian general-purpose electronic maps, without using high-precision surveying maps specifically for examination rooms; Visual recognition is performed on the collected images to determine the points deducted in driving tests or training. The vehicle location, real-time images, deduction results, and evaluation information are displayed synchronously on the general electronic map interface; The system automatically completes the scoring, recording, and prompting of driver's license tests or training based on visual recognition results.

[0011] 3. Core Innovation Points Visual image judgment is used to replace high-precision maps in the scoring process; It can directly use general civilian electronic maps, eliminating the need for surveying and mapping and resulting in extremely low costs; Images, maps, and evaluation results are displayed simultaneously on mobile phones and other common terminals. It is applicable to both driving test part 2 and driving test part 3, as well as daily training, and has strong versatility. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the embodiments.

[0014] System workflow: Turn on the vehicle-mounted camera and the site camera to capture real-time images of vehicles, wheels, and road markings; Open the universal navigation map on your phone or tablet and connect to the system; The visual judgment module identifies in real time whether the wheels are on the line, whether the body extends beyond the edge line, whether the parking is in place, and whether the lights are being used correctly. The recognition results are displayed on the map interface in real time, and the system automatically prompts and records when deductions occur; After the exam or training session, the system automatically generates a total score and evaluation report.
