Embodiment Construction

[0026] The vehicle of this embodiment is a self-driving car, which is equipped with a conventional laser sensor (Ibeo), a visual sensor (binocular vision camera), a position sensor (GPS), front and rear radars, and a main control computer (Nuvo-5095GC industrial computer) The composed automatic driving system can implement conventional sensor detection and driving control required for automatic driving.

[0027] see figure 1 , the self-driving car test scene construction method of the present embodiment includes the following steps S1-S3:

[0028] Step S1. Randomly combine narrow roads, curves, ramps, and straight roads to generate a virtual map, and at the ends of any two connected roads, control one of them to gradually change to converge to the other so as to realize the connection.

[0029] Since the road types can be divided into four types: narrow roads, curves, ramps, and straight roads, in order to ensure comprehensiveness, narrow roads, curves, ramps, and straight r...

Abstract

The invention relates to an automatic driving automobile test scene construction method and device and a storage medium. The method comprises the following steps: S1, randomly combining four types ofroads including a narrow road, a curve road, a ramp road and a straight road to generate a virtual map, and controlling one of the end parts of any two connected roads to gradually change to tend to the other road so as to realize connection; s2, specifying a departure place and a destination on the virtual map, and generating a driving path according to the departure place and the destination; and S3, randomly generating an obstacle on a road related to the driving path. According to the invention, the narrow lane, the bent lane, the ramp and the straight lane are randomly combined to ensurethe comprehensiveness of the road types in the test map, and the diversification of the types and positions of the obstacles is ensured by randomly generating the obstacles on the roads involved in the driving path, so that the purposes of enriching the test scenes and improving the diversity and variability of the test scenes are achieved.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to a method, device and storage medium for constructing a test scene of an automatic driving vehicle. Background technique [0002] Autonomous vehicles need to be tested before they are put into use. Existing test scenarios are often simulated manually with reference to car accidents. Comprehensiveness. Contents of the invention [0003] The present invention solves or partly solves the deficiencies in the prior art, and provides a method, device and storage medium for constructing an autonomous vehicle test scene. [0004] For this reason, a kind of self-driving car test scene construction method is provided, comprising the following steps: [0005] Step S1. Randomly combine narrow roads, curves, ramps, and straight roads to generate a virtual map, and at the ends of any two connected roads, control one of them to gradually change to converge to the other so as to real...
