Problems solved by technology

However, for some specific scenarios, it is difficult to reproduce stably, which is very important in the testing process of testing the control system of unmanned vehicles
For example, the test of vehicle collision risk and pedestrian collision risk can use dummy people and fake cars, but once a collision occurs, it is easy to cause damage to dummy people, fake cars and even unmanned vehicles, making the cost high and the test efficiency low
At the same time, it is difficult for this type of test method to control the precise movement of obstacles to achieve stable reproduction of the scene

Abstract

The embodiment of the invention discloses a test method and device, and equipment and a medium. The method includes: generating virtual scene data according to a test requirement and a current drivingstate data of a to-be-tested vehicle; combining the virtual scene data with actually measured scene data to form final scene data; and according to the final scene data, controlling the to-be-testedvehicle. Therefore, a problem that the scene reproduction cost is high and the test efficiency is low when the unmanned vehicle control system is tested at a specific scene is solved. A controllable obstacle can be injected into the vehicle control testing process; and precise controlling of an obstacle is realized and the specific scene is reproduced stably. Meanwhile, since the virtual obstacledoes not have maintenance and repairing problems, an objective of saving the test cost is achieved.

Description

technical field [0001] Embodiments of the present invention relate to vehicle driving control technologies, and in particular to a testing method, device, equipment and medium. Background technique [0002] Autonomous vehicle technology is constantly evolving, and both the hardware and software features required for vehicle control are continually being improved and updated. In order to ensure the safety of the vehicle, it is usually necessary to test various performances of the vehicle to test the ability of the vehicle to collect and identify environmental data, and to perform response control based on the identification results. [0003] The actual scene of vehicle driving is very complex and changeable, and the test process also requires comprehensive testing of each scene. However, for some specific scenarios, it is difficult to reproduce stably, which is very important in the testing process of testing the control system of unmanned vehicles. For example, the test of...
