| description | Disclosed is crash detection using smartphone sensor data. A method implemented in a smartphone associated with a transportation apparatus to detect a crash of the transportation apparatus, comprisesreceiving a signal generated in time domain by a sensor of the smartphone in response to an event triggered by motion of the smartphone. The method further comprises transforming the signal to a delaydomain to generate a two-dimensional representation of the signal in the delay domain. The method further comprises processing the two-dimensional representation using a Hough transform to select lines from the two-dimensional representation having a parameter greater than or equal to a predetermined threshold. The method further comprises determining a pattern associated with the selected lines,comparing the pattern to a predetermined pattern indicating crash event of the transportation apparatus, and determining based on the comparison whether the event indicates crash event of the transportation apparatus.
