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

[0015] 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:

[0016] First, place the camera at the driving position of the camera car, simulate the driver's field of vision, and shoot the scene video of the actual road 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, so...

Abstract

The invention relates to research of setting reasonability of road traffic virtual signs and marks, in particular to an establishing method of a simulation test platform of the road traffic virtual signs and marks. The method comprises the following steps: first, shooting a scene video of an actual road by simulating the view of a driver by a vidicon as an original video; second, obtaining path tracking parameters of the vidicon; then, adding drawn signs and marks to the original video by an adding vidicon function by Maya software, and obtaining a real scene video with virtual signs and marks through video synthesis and rendering as a simulating scene; and finally, inputting the simulating video into a simulating driving system to be matched with a driving simulator, so that the simulation test of the virtual signs and marks based on the 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 research abroad also shows 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 reduc...
