Title:
VEHICLE-ROAD COLLABORATION-BASED SENSED ROADSIDE TEST DATA QUALITY EVALUATING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/021871
Kind Code:
A1
Abstract:
The present invention relates to the technical field of vehicle-road collaboration, and provides a vehicle-road collaboration-based sensed roadside test data quality evaluating method. The vehicle-road collaboration-based sensed roadside test data quality evaluating method involves an adaptive fusion regression trajectory quality evaluation model, the adaptive fusion regression model consisting of two networks, i.e., evaluation and correction networks. The method comprises the following execution steps: S1, calculating related indexes of trajectory rationality and fluctuation of roadside vehicle trajectory data, and inputting the indexes into the evaluation network for fusion regression calculation to obtain a quality evaluation result. According to the vehicle-road collaboration-based sensed roadside test data quality evaluating method provided by the present invention, trajectory data quality can be effectively represented; for a multi-vehicle interaction scenario, although the correlation between a vehicle interaction rationality index and trajectory quality is weak and the index has a limited range of application, using the vehicle interaction rationality index as a supplement of other evaluation indexes can be considered, such that a better effect of vehicle-road collaboration-based sensed roadside test data quality evaluation is realized.
