Road data acquisition and simulation scene establishment integrated system and method

Abstract

The invention relates to a road data acquisition and simulation scene establishment integrated system. The integrated system comprises a sensor acquisition unit, a data fusion center and a road environment analog simulation platform which are connected in sequence. The sensor acquisition unit comprises: an assembly A which is a vehicle front-view camera and a millimeter-wave radar fusion group; anassembly B which is a laser radar group arranged at the half-vehicle-height position and comprises at least six 110-degree sub laser radar sensors; an assembly C which is a laser radar group arrangedon the roof and comprises three laser radars; and an assembly D which is an IMU and GPS group arranged in the middle of the vehicle. The collected environment data is used for scene analog simulationand generating a corresponding test case. The system is used for solving the problems that: in the prior art, the cost of collecting vehicle road tests is high, the vehicle road tests are not coupledwith a built simulation environment, and an environment scene cannot be automatically generated. The system can widely cover potential types of driving scenes possibly encountered by automatic driving vehicles, and greatly reduces kilometers needing road testing.

Description

technical field [0001] The invention relates to the field of data collection of road objects, in particular to an integrated system and method for road data collection and simulation scene establishment. Background technique [0002] In recent years, the rapid development of intelligent driving technology and road test evaluation standards has put forward higher requirements for all aspects of intelligent driving road tests. In the process of data collection, the perception, storage and data synchronization processing of scene objects around the road need high-quality assurance; in the process of scene simulation using existing data, the automation and integration of the simulation process and the authenticity and accuracy of the simulated environment Degree requirements are getting higher and higher. Therefore, a highly adaptable, standardized and reliable acquisition device is the guarantee for the safety of autonomous driving technology and the basis of the road scene te...
