Construction method of special marker in vehicle automatic driving virtual environment

Abstract

The invention provides a construction method of a special marker in vehicle automatic driving virtual environment. The method comprises the following steps of: step I: determining the type of a modelneeding to generate a special type marker, and acquiring corresponding model parameters; step II: calling an application program interface corresponding to the special type marker model, and executinga generation algorithm, thereby obtaining a marker object description compatible with a virtual scene; and step III: outputting the marker object to a memory. In addition, the invention also providesa construction method of vehicle automatic driving virtual environment based on the marker. By adopting the road generation algorithm in the construction method of the special marker of the invention, special markers such as roads and the like can be vividly simulated, and data acquisition and road adjustment in a simulation environment are facilitated. In addition, a virtual target object and aspecial type marker are generated in the invention through a program software to replace an acquisition process of a scene and the marker of the real world, thereby avoiding using expensive acquisition equipment and reducing the cost.

Description

technical field [0001] The present invention relates to the technical field of combination of pattern recognition and intelligent systems with vehicles, in particular to a construction method of markers in a virtual environment for automatic driving of vehicles and a virtual environment including the markers. Background technique [0002] With the improvement of people's living standards, vehicles such as cars have become the main means of transportation for people, and the intelligence of vehicles has increasingly made travel easier. In some cases, the vehicle can automatically perform the driving task, for example, an ordinary family car, bus, truck and other vehicles with the automatic driving function turned on, or it can also be an unmanned family car, bus, truck and other vehicles. When the vehicle is performing automatic driving, it needs to obtain the vehicle decision-making line according to the pre-configured vehicle decision-making planning algorithm, and then exe...

Problems solved by technology

At present, when building a virtual environment, the collection of road conditions or driving road scene data requires expensive collection equipment, or requires difficult collection methods such as driving around, or does not collect enough data due to extremely difficult occurrence of extreme events. data

Especially the special landmarks involved, such as: roads, lane lines, traffic signs, street lights, trees, etc., although these are common in daily life, they are difficult to simulate in the existing technology in the unmanned simulation environment. Lack of realistic simulation data
