AI Technical Summary

Technical Problem

In traffic management at modern road intersections, it is difficult for a single sensor to fully and accurately perceive and track the status of all traffic targets, making it difficult for the traffic management system to make timely and effective decisions.

Method used

The multi-sensor data fusion method is adopted, including obtaining the data and GPS information of multiple sensors, performing pre-processing and further data processing, synchronizing the data using precision time protocols, establishing a fusion coordinate system, and filtering and merging the target information collected by the sensor through target overlap.

Benefits of technology

Through the integration of multi-sensor data, the accuracy and real-time data are improved, and intuitive traffic scene display is generated, helping traffic managers make more reasonable and timely judgments and decisions, and improving traffic management efficiency and decision-making support capabilities.

Abstract

The present invention relates to a multi-sensor data fusion method, device, equipment and medium, including: obtaining data and GPS information of multiple sensors such as binocular cameras and radars, preprocessing as input data, the preprocessing includes one or more of image color space conversion, filtering and denoising, and data decryption; further processing the preprocessed data, the processing includes one or more of target detection and tracking, coordinate system conversion, target UID allocation, and bird's-eye view projection; using the precision time protocol (PTP) to synchronize the processed data of multiple sensors to keep the time consistent; selecting the center point of the road intersection and recording GPS information, establishing a fusion coordinate system, calculating the sensor and target position information according to the GPS information of the sensor, mapping it to the fusion coordinate system, screening and merging the target according to the overlap threshold, and associating information such as speed and distance with UID. The present invention realizes modeling and display of the entire intersection, providing a reliable basis for traffic management decisions.
