An Effective Method of Automatic Classification of Drive Recorder Data Using Acceleration Waveform
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
Drive recorders have been used more frequently in Japan on the transportation vehicles such as taxicabs, buses and trucks than before. The drive recorder, however, can record a large number of "non-hazardous data" which are not the accident or near-accident data when the car passes the undulation or bumps on the road. The authors will show a new method of automatic classification of the drive recorder data into some categories including "accidents," "near-accidents," "bound" and so on using the waveforms of the acceleration data, which is much more effective than the current similar methods.
