Vehicle speed detection
Determining of vehicle speed by using signal analysis on engine speed acoustic
Moving vehicle speed is usually determined by using Radar, Photo Radar, Drone Radar, LIDAR Speedometer Clocks, Average Speed Computers, Aircraft or Video frame methods, etc.
In this solution, an audio-based vehicle speed calculation method is presented, which has the capability of calculating the speed as well as traveled distance and estimating gear shift points with high accuracy.
Based on the frequency analysis of an audio signal, the method shows satisfactory performance in counting engine rpm at any given moment. According to the peaks in this parameter, it has become possible to determine gear shifts.
