vehicle related data acquirement system for improving enhancing accuracy of detection

摘要

When a pair of laser signals emitted in such a manner as to be spaced apart in the longitudinal direction with the same width of a lane are emitted, the amount of data to be utilized for vehicle data detection is increased by emitting a plurality of pairs of laser signals, It is possible to greatly increase the accuracy and reliability of detection, simplify installation, maintenance and maintenance, reduce cost, and reduce the vehicle speed of each of the detected vehicle data and the first set value TH1 And more particularly, to a vehicle data detection system capable of significantly increasing the accuracy and reliability of detection and significantly reducing complaints caused by erroneous data detection by accurately detecting errors and malfunctions that occurred during vehicle data detection.;
