Method for establishing simulation experiment platform of road traffic virtual identifier marking

A simulation test and marking technology, applied in the field of the establishment of a simulation test platform, can solve the problems such as the lack of close connection of the actual application road, the lack of realism of the test, and the credibility of the impact evaluation, so as to make up for the failure to reflect the real road environment and solve the cost. High, simple to achieve the effect of the process

Problems solved by technology

Since the test scene is a virtual road scene, the test lacks a sense of reality and is not closely related to the actual application road. The gap between the evaluation of the test effect and the actual road use is too large, which affects the credibility of the evaluation.

Embodiment Construction

[0014] The method for establishing the simulated test platform of road traffic virtual signs and markings of the present invention is based on the real scene video of the road, and specifically includes the following steps:

[0015] First, the camera is placed at the driving position of the camera car to simulate the driver's field of vision, and the scene video of the actual road is shot at a constant speed as the original video. Specifically: arrange a tripod on the right side of the driving position, and then install the camera on the tripod so that the camera is just about 10 cm below the interior rearview mirror. Choose a digital camera to shoot a video of the test road. When the video is taken, the vehicle drives at a constant speed in the center of the lane as much as possible. When recording, mark the apparent height of the camera's viewpoint. At the same time, the shooting point of view is required to coincide with the driver's actual point of view as much as possible...

Abstract

The invention relates to the reasonable research on the arrangement of road traffic identifier markings, in particular to a method for establishing a simulation experiment platform of a road traffic virtual identifier marking, comprising the following steps: firstly, a camera is utilized to simulate the visual field of a driver and shoot the scene video of an actual road as the original video; secondly, the path tracking parameters of the camera are obtained; then, a drawn identifier marking line is added on to the original video by utilizing the function of adding a camera of Maya software to obtain the real scene video with virtual identifier marking as the simulation scene after video synthesis and rendering process; and finally, the simulation video is input into a simulation driving system and matched with a driving simulator, and then the simulation experiment on virtual identifier marking based on road real scene video can be carried out.

Description

technical field [0001] The invention relates to research on the rationality of setting road traffic sign markings, in particular to a method for establishing a simulation test platform for road traffic virtual sign markings. technical background [0002] Road traffic signs and markings play a very important role in the road traffic system. According to statistics, the investment of traffic signs and markings is less than 2% of the total cost of road construction, but the role it plays is irreplaceable. Relevant studies abroad also show that the correlation rate between signs and markings and accidents is as high as 72%, and reasonable setting of signs and markings can increase the transportation efficiency by 30%. On the premise of not changing the existing road alignment and carrying out large-scale civil engineering transformation, improving road traffic signs and markings to provide drivers with necessary traffic safety information is one of the effective ways to reduce ...
