Extensional Smartphone Probe for Road Bump Detection

摘要: When a wide area disaster like an earthquake is occurred, immediate monitoring and sharing of traffic situation road conditions are important for the quick rescue operation at area. A bump one kind condition which needed to sharing. But currently, because detection done by human visual confirmation mechanical measuring surface shapes using profile meter, it needs use many resources, long lead time special equipment. In this paper, method proposed that can be more easily, named Bump Recorder. That extensional smartphone probe only put on vehicle dashboard, driven as usual. At first, prototype Recorder in used pedometer, principle actual measurement result, explained, was measured Niigataken Chuetsu-oki Earthquake 2007. And next, first generation three-dimensional accelerometer installed smartphone, logic experiment result explained. last, second gyro sensor,
