Abstract

The invention discloses an automatic driving education trolley testing method and system based on a simulation scene, and the method specifically comprises the steps: building a simulation scene based on a high-precision semantic map, and configuring a simulation education trolley and a dynamic obstacle in the simulation scene; setting up hardware equipment, wherein the hardware equipment comprises visual equipment and a real education trolley, and the real education trolley can run on the visual equipment; enabling the hardware equipment to interact with simulation scene information so that a real education trolley and a simulation education trolley run synchronously, absolutely accurate position, obstacle and sensor information in simulation is provided for an automatic driving algorithm, and the problem of experiment difficulty caused by off-site interference is avoided; a user can design a test scene (road network, traffic flow, traffic light and the like) by himself / herself, the teaching content is richer and more flexible, and the cost of platform building is reduced; and finally, in the method, the real education trolley only moves in a small range, so that the safety of practical teaching is greatly improved.

Description

technical field [0001] The invention belongs to the field of an automatic driving teaching platform, and in particular relates to a test method and system for an automatic driving education car based on a simulation scene. Background technique [0002] The development of the automotive autonomous driving industry is facing a large talent gap. From R&D and design to production and maintenance, a large number of scientific research and technical personnel are required. However, domestic colleges and universities do not yet have supporting models, courses and experimental methods from personnel training to teaching systems. The autonomous driving education platform mainly includes autonomous driving vehicles, supporting sensors, and test sites. Each part requires considerable cost. Problems such as hardware equipment damage and excessive scene interference information have brought unnecessary troubles to teaching. Therefore, introducing simulation information into the autonomou...
