Problems solved by technology

However, because the vehicle is not a rectangular entity with a simple structure, there are hollow parts. If these hollow parts happen to come out between the infrared devices, a misjudgment will occur.
Based on this, there is a GPS-assisted judgment, which judges by simulating the positional relationship of the positioning points on the vehicle in the examination room; however, the application of GPS is limited in some occasions

Embodiment Construction

[0012] Below in conjunction with example the present invention will be further described.

[0013] The road test evaluation method based on the combination of Beidou positioning and digital modeling technology includes the following steps:

[0014] (1) Establish a model of the test site according to the set ratio compared with the actual test site; build a model of the test vehicle according to the same ratio compared with the actual test site;

[0015] (2) Set two positioning marks on the roof of the actual test vehicle, and mark the two positioning marks in the test vehicle model, and record them as two model reference points;

[0016] (3) Locate the two reference points through the Beidou positioning system, obtain the position and heading angle information of the two reference points relative to the actual test site, determine the corresponding positions of the two model reference points in the test site model, and calculate the test vehicle The position of the model in t...

Abstract

The invention discloses a road test judgment method based on a technology combining Beidou positioning with digital modeling. The method includes the processes of establishment of a test site model and a test vehicle model, Beidou positioning, conversion of vehicle conditions in the test site model, and judgment of test grades according to the geometrical relationship between the test vehicle model and the test site model. By the adoption of the road test judgment method based on the technology combining Beidou positioning with digital modeling, positions and relative directions of vehicles can be intelligently located, the vehicle position conditions can be accurately stimulated with the combination of the models, and accuracy of road test judgment is improved. In addition, a Beidou positioning system can be more easily accepted by domestic special users, such as troops.

Description

technical field [0001] The invention relates to a road test evaluation method based on the combination technology of Beidou positioning and digital modeling, which belongs to the automatic evaluation technology for driver examination. Background technique [0002] The current road test generally uses the infrared measurement method to judge the current touch bar and line. When the bar touches the line, the vehicle intercepts the communication between the infrared transmitter and the infrared receiver. However, since the vehicle is not a rectangular entity with a simple structure, there are hollowed out parts. If these hollowed out parts happen to come out between the infrared devices, a misjudgment will occur. Based on this, GPS-assisted judgment has emerged, which can be judged by simulating the positional relationship of the positioning points on the vehicle in the examination room; however, the application of GPS is limited in some occasions. Therefore, a new method is u...
