Roadside device

Abstract

The invention provides a roadside device. The roadside device comprises a plurality of roadside supports arranged on one side or two sides of a road; the plurality of sensors are used for detecting a road and are distributed on the plurality of roadside brackets, and the detection areas of any one and / or the plurality of sensors of the adjacent roadside brackets in the longitudinal direction of the road are overlapped; the acquisition module is used for receiving data sent by the plurality of sensors respectively; the first sensing module is used for determining respective first sensing data of the plurality of sensors based on the data output by the acquisition module; the second sensing module is used for determining respective second sensing data of the plurality of overlapping regions based on the output of the first sensing module; the parameter determination module is used for determining space fusion parameters and / or time fusion parameters of a plurality of sensors for detecting the overlapping regions based on the second sensing data of the overlapping regions for each region of the overlapping regions; the monitoring module is used for monitoring the road based on the output of the first sensing module and the output of the parameter determination module, and the real condition of the road can be reflected more accurately.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a roadside device. Background technique [0002] With the rapid development of social economy, intelligent transportation is an important means to realize road safety monitoring. However, the road traffic environment is becoming more and more complex, and the requirements for road traffic management are getting higher and higher. The existing road management methods can no longer meet the needs of intelligent management and diversified travel services. In order to achieve fine road management and control, multi-source traffic information holographic perception and high-quality traffic data extraction technologies are urgently needed. [0003] In related technologies, although multi-source traffic information can be obtained, there is an urgent need for a more effective way to obtain and process multi-source traffic information to accurately reflect the real si...

Problems solved by technology

[0004] The invention provides a roadside device. On the one hand, it can realize the correction of time and space calibration of different sensors, effectively solve the problem that the data sensed by different sensors are not synchronized in time and space after the sensors have been running for a period of time, and improve The accuracy of subsequent data fusion is improved, so that the real situation of the road can be more accurately reflected, and the intelligent management and operation level of the road can be improved.
