Abstract

Sposób i urządzenie do mierzenia prędkości pojazdu, zawierające: zapewnienie czujnika laserowego skonfigurowanego do tworzenia płaszczyzny wykrywania między podłożem a górną krawędzią koła pojazdu (S110); emitowanie wielu wiązek laserowych pod różnymi kątami do każdego z kół przy zadanej częstotliwości skanowania, gdy co najmniej jedno z kół zostanie wykryte w momencie wchodzenia w płaszczyznę wykrywania; odbieranie informacji o wykryciu uzyskanych przez czujnik laserowy, przy czym informacja o wykryciu zawiera pierwsze odległości każdego z kół od położenia, w którym wiązki laserowe są emitowane w różnych momentach i kąt emisji lasera odpowiadający każdej z pierwszej odległości; oraz obliczanie prędkości przemieszczania się każdego z kół w oparciu o pierwsze odległości w różnych momentach i kąt emisji lasera odpowiadający każdej z pierwszej odległości. Poprawiony może być wskaźnik dokładności pomiaru prędkości.A method and apparatus for measuring vehicle speed, comprising: providing a laser sensor configured to form a detection plane between the ground and an upper edge of a vehicle wheel (S110); emitting a plurality of laser beams at different angles to each of the wheels at a predetermined scanning frequency when at least one of the wheels is detected while entering the detection plane; receiving detection information obtained by the laser sensor, the detection information including the first distances of each of the wheels from the position at which the laser beams are emitted at different times and the laser emission angle corresponding to each of the first distance; and computing the speed of travel of each of the wheels based on the first distances at different times and the laser emission angle corresponding to each of the first distance. The accuracy of the speed measurement may be improved.
