TRIGGER DETECTION METHOD, APPARATUS AND SYSTEM

WIPO Patent Application WO/2020/211658

A1

Disclosed are a trigger detection method, apparatus and system. The system comprises a road surface detection apparatus for detecting, by means of a first sensor buried in a target detection area on a road surface, an event of a vehicle passing through the target detection area; a roadside detection apparatus for detecting, by means of a second sensor mounted on a roadside device and capable of covering the target detection area, the event of a vehicle passing through the target detection area; and a fusion algorithm processing apparatus for determining, according to the fusion of a road surface detection result from the road surface detection apparatus and a roadside detection result from the roadside detection apparatus, whether there is a vehicle passing through the target detection area, and generating a trigger signal according to a determination result. By means of the embodiments of the present application, the false detection rate and the missing detection rate in a trigger detection phase can be reduced, thereby improving the accuracy of license plate recognition and enabling senseless payment to be more fully applied in an expressway scenario.
