Abstract

The invention provides a method, a device, equipment, a medium and a product for testing perception time delay, and relates to the technical field of intelligent transportation, in particular to the technical field of system testing. The specific implementation scheme is as follows: in response to determining that a target vehicle receives a sensing data set sent by roadside sensing equipment, determining a data receiving timestamp and a data acquisition timestamp corresponding to each piece of sensing data in the sensing data set; for each piece of sensing data in the sensing data set, determining a data delay corresponding to the sensing data based on the data receiving timestamp and the data acquisition timestamp corresponding to the sensing data; and generating a sensing data time delay test result based on the data time delay corresponding to each sensing data in the sensing data set. According to the implementation mode, the end-to-end time delay of the roadside sensing equipment can be tested, so that the time delay of the roadside sensing equipment can be controlled within a certain range based on a test result, and the transmission timeliness of sensing data is improved.

Description

technical field [0001] The present disclosure relates to the technical field of intelligent transportation, specifically the technical field of system testing. Background technique [0002] In the application scenario of intelligent transportation, the vehicle-road collaborative roadside perception system can realize the coordinated scheduling of people, vehicles, and roads through multiple components such as the traveler subsystem, the vehicle subsystem, the roadside subsystem, and the central subsystem. [0003] Among them, the roadside sensing device in the roadside subsystem will detect and identify the road traffic operation status, traffic participants, and traffic events, obtain sensing data, and send the sensing data to the roadside computing device, so that the roadside computing device The perception data is fused to generate a structured perception message. However, there will be a certain delay between the time when the roadside sensing device collects the sensi...
